From Wikipedia, the free encyclopedia

International maritime signal flags are various flags used to communicate with ships. The principal system of flags and associated codes is the International Code of Signals. Various navies have flag systems with additional flags and codes, and other flags are used in special uses, or have historical significance.

There are various methods by which the flags can be used as signals:

A series of flags can spell out a message, each flag representing a letter.

Individual flags have specific and standard meanings; for example, diving support vessels raise the "A" flag indicating their inability to move from their current location because they have a diver underwater and to warn other vessels to keep clear to avoid endangering the diver(s) with their propellers.

One or more flags form a code word whose meaning can be looked up in a code book held by both parties. An example is the Popham numeric code used at the Battle of Trafalgar.

In yacht racing and dinghy racing, flags have other meanings; for example, the P flag is used as the "preparatory" flag to indicate an imminent start, and the S flag means "shortened course" (for more details see Race signals).

NATO uses the same flags, with a few unique to warships, alone or in short sets to communicate various unclassified messages. The NATO usage generally differs from the international meanings, and therefore warships will fly the Code/answer flag above the signal to indicate it should be read using the international meaning.

During the Allied occupations of Axis countries after World War II, use and display of those nations' national flags was banned.[citation needed ] In order to comply with the international legal requirement that a ship identify its registry by displaying the appropriate national ensign, swallow-tailed versions of the C, D, and E signal flags were designated as, respectively, provisional German, Okinawan, and Japanese civil ensigns. Being swallowtails, they are commonly referred to as the " C-pennant" (German: C-Doppelstander), " D-pennant", and " E-pennant".[citation needed ]

The signal flags for M, T, V and X are respectively similar to the flags of Scotland, France, the Saint Patrick's saltire and the flag of Finland.

Letter flags (with ICS meaning)

Notes

Substitute or repeater flags allow messages with duplicate characters to be signaled without the need for multiple sets of flags.

The four NATO substitute flags are as follows:

First substitute

Second substitute

Third substitute

Fourth substitute

The International Code of Signals includes only the first three of these substitute flags. To illustrate their use, here are some messages and the way they would be encoded:

Fun LEGO computer coding for kids! Technology is a huge part of our lives today. My son loves his iPad and although we monitor his use of it, it's a part of our home. We also love LEGO activities and have tons of fun building neat contraptions and gadgets with our bricks. We have played around with a couple of fun ways to do computer coding with LEGO® with and without a computer.

FUN LEGO CODING ACTIVITIES FOR KIDS!

LEGO CODING FOR LEARNING

Computer coding with LEGO® is a great introduction to the world of coding using a favorite building toy. Yes, you can teach young kids about computer coding, especially if they are highly interested in computers and how they work.

My son was astounded to hear that a person actually wrote/designed the Minecraft game. We even had to use the iPad to lookup more about this guy. With the realization that my son could very well make his own game someday, he was pretty interested to learn more about computer coding.

How can you combine computer coding and LEGO®?

There are a few ways you can combine computer coding with LEGO® for the younger crowd or depending on the skill level. My son is kindergarten age and is also highly interested to learn more at this time. You can test out the world of computer coding on and off the computer.
Looking for easy to print activities, and inexpensive problem-based challenges? We have you covered... Click below to get your brick binary code activity.
LEGO CODING GAMES

I was introduced to Bits and Bricks, an online computer coding game made by LEGO® . It is part of the Hour of Code initiative aimed towards kids as young as 5 and 6, to get them excited about computer coding. Hour of Code is a global project reaching millions of kids. You can find many versions of Hour of Code to try out. Of course, the LEGO® lovers that we are, we enjoyed working with Bit the Bot.

BINARY ALPHABET

Our computers don't read the letter A like we read the letter A. The computer has a special code called the binary alphabet where each letter, both upper and lower case is assigned a set of numbers containing 1's and 0's.

My son first encountered this at school, but it was an activity for an older grade. He was curious so I read up on the binary alphabet and showed him how it worked. Mom has some learning to do too! We made a computer coding Christmas ornament. You can also take a base plate and LEGO® bricks and play around with the binary alphabet.

BUILD MINI LEGO ROBOTS

LEGO coding doesn't have to be just about the computer. Grab a bin of LEGO® pieces including the neat, super tiny pieces and see if you can make your Bit the Bot from Bricks and Bits mentioned above. Can you use your LEGO bricks to make a robot?

DIY LEGO CODING ALGORITHM GAME

You have a robot made, now make a coding game for it. Create a world with obstacles or an algorithm game. Make movement cards including forward, right turn, and left turn. Set a challenge with a start and a finish, and code your Bot to get through the obstacle course.

Layout the direction cards to plot the movement of the robot then try out your code and see if you are right! Create a new challenge and try again. It's a fun way to play with code and LEGO®! Read more about algorithms here ( and look for a FREE game printable).

Introduction: Cardboard Cryptex Safe!

A cryptex is a portable vault used to hide messages and valuables. Most cryptexes are built from robust materials such as metal and wood. However, a cryptex can also be built out of cardboard. A cardboard cryptex is easier to build than a metal or wooden one. Obviously, a cardboard cryptex is just for show and is not intended to be used as a real safe, but it is a cool craft to make, and it will show off one's gluing skills!

Step 1: A Video Overview

Here's a short little video that gives you an idea of how to build the cryptex. I also have more videos on my blog @ denialmedia.ca

Step 2: Tools and Materials

Materials:

Cardboard (about 1mm thick, I used a Special K Cereal box)

Two cardboard tubes (toilet paper tubes, it's not disgusting when its used for crafts!)

Slightly bendy cardboard (I used a Cheerios box)

Paper

Hot glue sticks (2-3)

Tools:

Glue stick

Hot glue gun

Compass (The one that draws circles)

Scissors

Exact-o knife or similar (dollar stores have cheap alternatives)

Box cutter

Step 3: Cutting the Cardboard

We're going to start this project off by cutting some cardboard circles:
The following dimensions are diameters. The radii are bracketed and underlined.
Circles:

2 80mm (40mm radius) circles

4 80mm (40mm radius) circles with 45mm (22.5mm radius) holes

4 79mm (39.5mm radius) circles with 45mm (22.5mm radius) holes

4 80mm (40mm radius) circles with 65mm (32.5mm radius) holes

4 62mm (31mm radius) circles with 45mm (22.5mm radius) holes

1 80mm (40mm radius) circle with a 45mm (22.5mm radius) hole

1 80mm (40mm radius) circle with a 44mm (22mm radius) hole

1 43mm (21.5mm radius) circle

1 42mm (21mm radius) circle

Be sure to mark a center hole on the circles (with the compass) as they are needed later.
Some circles need to have holes inside them. I found it best to go over the outside of the hole with an Exact-o knife first, then finish it off with the box cutter.

We are also going to need to cut some cardboard strips out of slightly flexible cardboard. The length for each strip is 251.3mm, but I opted to trim each strip after I glued it on.
Strips:

2 25mm wide strips

4 20mm wide strips

We will also need several small rectangles for the teeth of the key:
Teeth:

Step 4: Constructing the Key

The key of the cryptex is the part that slides into the base of the cryptex. It is also the part that has teeth (adding the teeth will come later).

Here are the cardboard parts to make the key:

80mm circle

80mm circle with 44mm hole

42mm circle

25mm strip

114mm tube

First start with the 80mm circle. Take the back side (the part with any text or pictures) and use your compass to draw a 42mm circle in the center. Hot glue the 42mm cardboard circle onto the back of the 80mm circle where you have just drawn the same size circle.

Take a cardboard tube and mark 25mm from the bottom. Then fit and glue is snugly over the 42mm circle that is glued to the 80mm one.

Then, glue the 80mm circle with the 44mm hole on to the 25mm mark you made on the cardboard tube.

Lastly, wrap the 25mm wide strip around the two 80mm circles and glue it on.

Step 5: Building the Base

The base is very similar to the key of the cryptex.

Here are the parts you will need:

80mm circle

80mm circle with 45mm hole

43mm circle

25mm strip

114mm tube with 10cm slot

Just like the key, center the 43mm circle onto the backside of the 80mm circle and glue it on. Use a ruler and cut a slot parallel to the tube. Cut a bit off the tube (~5 mm) so you end up with a 10mm gap in your tube. The tube should fit smoothly over the key of the cryptex.

Fit the 80mm circle with the 45mm hole onto the tube and sand the hole until the tube fits with no problems. Glue the ring 25mm from the bottom of the tube.

Then fit the tube over the 43mm circle that is glued onto the 80mm circle and glue the tube on. As before, cover up the 25mm gap with a 25mm strip of cardboard.

Step 6: Constructing the Rings and Spacers

The rings are constructed from three circles and each come with a spacer.

Here are the parts to building four rings:

4 62mm circles with 45mm holes (spacer, notched)

4 79mm circles with 45mm holes (notched)

4 80mm circles with 45mm holes (notched)

4 80mm circles with 65mm holes

4 20mm strips

The notched parts have 10x10mm notches cut out which line up once the ring is constructed.

Start by gluing the 80mm circle with 65mm hole on to the 79mm circle with the 45mm hole. This outer circle is used to hide the spacer. Cut out the 10x10mm notch that is illustrated in the photos above. Do this step four times.

Use the circles you just built to trace and cut out notches from the 80mm circles with 45mm holes. Glue the 20mm strips around the 79mm circles. Then, glue the 80mm circles with 45mm holes onto the other side of the strips, making sure the notches are lined up. This gives you a completed ring.

The spacers are the 62mm circles with 45mm holes and they also have notches cut out. They will be glued onto the base and will fit within the 80mm circles with the 65mm holes. That way, the rings can turn, but the spacers will keep them from rubbing up too much.

Three of the four spacers are optional! The only one you really need is the outermost one, however, adding all 4 spacers would mean less friction between the rings.

Step 7: Adding Teeth to the Key

The key will have teeth that will lock onto the base of the cryptex if any of the rings are rotated the wrong way.

You will need 8 13x9mm cardboard rectangles to build the 4 teeth.

Take your ring and mark out a 9mm line parallel to the tube of the key. Then put the rings and spacers onto the base in the order of ring, spacer, ring, and so on... Lining up the key with the base would give you the location to put the keys. They keys go into the inside area of the rings, the edges that are closer to the key. Take a look at the pictures to give you an idea. The key should be able to slide in with the teeth, but the teeth should not be crushed by the rings or spacers.

Glue the teeth in two layers, adding one rectangle first, then the second one on top.

Step 8: Assembly

Now it is time to put everything together! Make sure the rings and the key fit smoothly onto the base, if they don't, sand them down with some sandpaper (this creates a nice finish on the edges as well!). Be sure to mark out where the notches are on the rings, or you will have a hard time opening the cryptex later!

Take the base and put on a ring (spacer side up). Then put a spacer and glue it on. Repeat this pattern until you have four rings and four spacers on the base. The rings should spin freely; they should also have a spacer keeping the last ring from falling off. They key should slide in easily as well. Putting the key in and messing around the letters would lock the cryptex and it should not open until the letters are returned to where the notches match the teeth on the key. In essence, the cryptex is finished!

Step 9: Decorating With Paper

I added some paper strips to cover up the rings, base, and key. I added the letters before I cut out the paper, but after I applied it to the cryptex, I discovered that the pencil-drawn letters were barely visible. Highlighting them with a red sharpie did the trick.

I have teamed up with Post-it® Brand to create a fun learning activity that helps to make math facts stick in a fun engaging way.

You have probably heard of the term Summer Slide; it usually refers to the loss of reading skills children can face if they don't read over the summer. It turns out this happens with math skills too, especially math facts. Things like times tables that are still encouraged to know by heart, I always think of these as math's equivalent of sight words.

Over the summer many children, mine included, are encouraged by their teachers to go online and work on math facts. There are some great math programs that can help children but it's STILL screen time. New research conducted by the Post-it® Brand revealed that 85% of Generation Z (that's our kids) learn best from a mix of methods including writing down what they are learning. Check out this infographic!

Gather your materials. You will need some Post-it® Super Sticky Notes in various colors and sizes (these vibrant colors are Post-it® Super Sticky Notes from the World of Color Miami and Rio de Janeiro collections), a marker, and a wall!

Start by deciding what your message will be. I decided on "You are rad!" I wanted to keep it simple as we fit this activity into a pretty busy summer day and I'd rather a short, fun activity (that he will want to repeat) than forcing him into something - no one learns well when they are forced into it.

Next, give each letter a corresponding number.

Write out a decoder list with every letter of the alphabet. Make sure that the numbers you assigned the letters in your message are paired up with the correct letter.

Write out math equations on Post-it® Super Sticky Notes that give answers with the letters you need. For example, if the letter Y is in my message corresponded to the number 18 I would write 6×3 or 9×2 and use that Post-it® Super Sticky Note in place of the Y.

Place the Post-it® Super Sticky Notes with equations in order on your wall.

Add a note about what to do and the decoder sheet and invite your mathematician to the activity. Provide them with more Post-it® Super Sticky Notes to write the message and or answers to the equations on and stick up on the wall. In addition, provide them with Post-it® Flags to mark any equations they have trouble solving so that you can go back to them!

I think I should have written a longer message because this kid blew through it!

He completed the math equations, found the letters using the decoder, wrote the letters down on new Post-it® Super Sticky Notes and popped it all on the wall.

When I asked him what he thought (my kids are the harshest reviewers!) he loved it. It was just the right amount of movement, writing, and math. I love that my children have the option to use online tools to improve these ever important skills, but I am so happy that simple materials like Post-it® Super Sticky Notes can help me create hands-on activities in no time to provide a balance.

This activity proved to be a great way to make math facts "stick"!, Post-it® Brand is encouraging people nationwide, especially Gen Z students, to write down goals, aspirations, and more, as a way to make them stick and accomplish tasks, both big and small in the new school year. How do you help your kids Make it Stick? Join me in sharing with @Postit Brand on social media and using the hashtag, #MakeitStick.

As I mentioned above, this post is sponsored by Post-it® Brand, although the content and opinions are mine.
Make sure to keep up with all the ways to help your Gen Z kids learn by heading over to www.post-it.com/study and by following Post-it® Brand on Twitter, Instagram, Facebook and Pinterest!

Code Relay Game

Required:

paper and pencil for each patrol

Instructions:

Need an open field up to 200 yards long, depending on group sizes.
Create a simple code for numbers equalling letters, such as the example below. One leader is the Code Keeper.

Create coded messages - one for each group, but all should have about the same number of letters. Possibly easier for younger groups, such as duplicated letters or slightly shorter messages.

All group leaders gather with the game leader at one spot. 20 yards away stands another member of each group. 20 yards further stands another member. And so on for as many members are in the largest group. The last member in each group needs a paper and pencil. 20 yards past this last person stands the Code Keeper with the simple code.

To start the game, each group leader is given his group's coded message. As soon as he gets the message, his teammate 20 yards away runs to him. The group leader tells him as many of the numbers as he wants.
Then the member runs back to his starting point while the next in line runs to meet him. He relays the numbers then returns to the group leader for more numbers.
The 2nd member relays to the 3rd and so on until the last group member gets the numbers. He runs to the Code Keeper and tells each number. For each number, the Code Keeper tells him the corresponding letter which he writes down.

When the group has all the numbers transferred and decoded, the entire group gathers at the group leader and yells out the message in unison.

Groups with fewer members have less chance to mis-translate, but the last member must run further.
Groups may try to memorize many numbers or do them one at a time to be safe.

An example message (each member would run a little over 1/3 mile)
17, 21, 17, 10, 7, 7, 6, 21, 8, 13, 21, 8, 3, 13, 21, 19
W E W I L L B E P R E P A R E D

An example Code:
A - 3
B - 6
C - 9
D - 19
E - 21
F - 22
G - 14
H - 1
I - 10
J - 23
K - 4
L - 7
M - 11
N - 2
O - 5
P - 8
Q - 12
R - 13
S - 25
