To review, we discuss customary units. What country uses customary units? Student response: United States. So far we have learned about customary units of length. Someone raise your hands and tell me the customary units of length. Student response: yard, foot, inch, and mile. Those are the units of length to measure how long something is in length. Yesterday, we talked about customary units of capacity. That means how much a container can hold. What are some customary units of capacity? Student response: gallons, pints, quarts, and cups.

I let the students know that in today's lesson, we will talk about customary units of weight. When you are taking a test or measuring something, you have to know the correct customary units to use. If you are measuring length, you would not say that "this is one pint" because pint does not go with length. Pint is a unit of measure for capacity.

In today's lesson, I share information about customary units of weight using the following site.

I find that using different instructional strategies keep the students interested in the lesson.

On the screen, the units of weight are displayed: ounces, pounds, and tons. Which unit is the smallest? Student response: ounce. In the video, what did they say weighed about an ounce? Student response: a slice of bread. I tell the students to think back to when they have held a slice of bread. This is familiar to everyone. You know about how heavy the bread feels in your hand. That is about 1 ounce. I go on to remind them that in the video, it told us that a loaf of bread would be weighed in pounds because you have several pieces of bread together. The last unit of measure is tons. How many pounds does it take to make a ton? Student response: 2,000 pounds. I told the students to think about a car because a car if very heavy. C an anyone think of something else that can be weighed in tons? Student response: truck, rocket, and elephant. It is very important to measure things in the right units. For example, if we were going to measure a car, we wouldn't want to measure it in pounds because it is too heavy. But, as they state in the video, if we take the car pieces apart, such as the door or tire, we can then weigh those individual items in pounds. Collectively, the car would be weighed in tons.

I let the students know that they will work in pairs to practice the skill further.

Exploring volume science is fun and easy to set up for kids! We enjoy using everyday items to test out our science ideas. So many classic science experiments can be done around the house! Grab some different size bowls, water, rice and something to measure with and get started! Make sure to check out our water absorption activity with sponges too!

Volume Science Experiment Set Up

This quick and easy volume science experiment is part of our A-Z STEM science for kids month. Science, technology, engineering, and math are so important for children to explore even at an early age! STEM can be quick and playful like this simple experiment. What is STEM?. Make sure to read and find out.
SUPPLIES
different size bowls, water, food coloring

rice or other dried filler {we have lots of sensory bin filler ideas and non food fillers too!}

1 Cup Measuring Cup, Large container to catch the spills

Put all your containers in a large bin so you don't have to worry about water everywhere! I measured 1 cup of water into each container. Add food coloring as desired.

Volume Science Experimenting

Let the volume science experimenting begin! I measured one cup of water into each container. I did this before I called him over so he wouldn't know it was the same amount of water in each container.

I chose an interesting mix of shapes and sizes so we could really check out the idea behind Volume! Add color. I picked out 6 containers, so he could make a rainbow and practice color mixing too.

What is Volume? For our volume science experiment, we went with a simple definition which is the amount of space something occupies. This definition is perfect for checking out what the same measurement of water looks like in different size containers.

He guessed that the yellow water container had the most volume. He was quite surprised when we dumped each container back into the measuring cup. They all head the same amount of water but looked different! He wanted to do more, so I set out three mason jars of different sizes.

He poured and measured 2 cups of water into each one. After the second one {medium sized} jar, he guessed the smallest one would overflow! We talked about the volume being "too much" for the smallest container.

Volume science on a basic level can be easy and fun for kids to explore!

Want more volume science? What about solids? Will the same thing happen? Let's see. This time he wanted to measure the rice into the same containers {thoroughly dried!} Then he wanted to pour each one back into the measuring cup.

Somewhat messy, but that's what the bin is for! We also repeated the three mason jar experiment but was surprised that the middle jar came closer to overflowing. He of course guessed the smallest jar would overflow as well.

Encourage exploration with hands-on volume science experiments. Ask questions. Compare results. Discover new things!

This activity allows manipulation and investigation of various types of angles. The online protractor tool can be used to practice measuring angles. It can be used at a variety of different grade levels. At its most basic for teaching about types of angles, acute, obtuse or reflex. For more advanced use to create angle problems in which the missing letter angle values have to be found. You can click and drag the handles to change the angles and the values will updated.

The controls

The mode control is used to it selects the type of angle problem.

Next to this is number of lines. But please note this control is disabled for both 'one' and 'intersect' modes.

the random button sets each angle to a random value

the equals button make all the angles equal.

the Protractor button when clicked will show or hide a protractor

Paper can select spots, squares or none for the background.

Use the angles display to choose whether to show or hide angles

In all the modes individual angles can be shown or hidden for example click the angle (a). Notice when the value is hidden the angle value next to the angle arc is replaced by the corresponding letter.

The handles at the end of each line can be clicked and dragged to change the angle.

Mode 'one' Identifying angle types.

The initial mode is unique in that there is only one angle. This mode is great for identifying various types of angles. Click the angle type ctrl to either show or hide the type. So now you can change the angle by dragging a handle or clicking dice for a random value. The angle types definitions are listed in the glossary below.

Complementary Angles mode

In this mode a complementary angle is shown, complementary angles add up to 90° Initially the 90° is split by just one line but this can be changed by selecting a different number of lines. A standard school problem is to have one missing angle that needs to be calculated. You can produce infinite such problems by selecting calculate from angles display, now press dice for a new problem.

Supplementary Angles mode

Supplementary angles are angles that add up to 180°. This mode behaves exactly the same as the previous.

Angles at a point mode

The angles at a point add up to 360°. In this mode press = button to make all the angles equal. This can be good way to start a problem followed by small adjustments to the lines by dragging.

Angles at intersecting lines mode

The final mode deals with angles produced by an intersection of two lines. If you have selected calculate you will notice that only one angle is given and all the other 3 can be worked out using the vertically opposite rule, or spotting the supplementary angles.

Angles Glossary

Acute Angle

Any angle that is less than 90°

Right Angle

An angle that is 90°

Obtuse Angle

An angle greater than 90° but less than 180°

Straight Angle

An angle of 180° which makes a straight line

Reflex Angle

An angle greater than 180°

Related activities

The interactive clock angles activity can also be used in explaining angles.

We have learned about fractions, and fractions on a number line, so now I want to show you a tool we use all the time that shows us fractions on a number line and also helps us measure.....a ruler.
Here we discuss why we need rulers and what they are used for. I invite students to share some of the ways they use rulers and have used them before.

There are 2 ways that we are going to think about measuring things today: in standard units and non-standard units.

I discuss the differences between standard units (mm, cm, in) and non-standard units (a cube, paperclip, whistle, and so on) and introduce the Anchor Chart that helps students see how they can use these items to estimate length. I want to ensure students have tangible things that they can associate with different standard units (MP5).
