We usually have at our homes tons of powerful and very cheep materials to use in Math classroom: the shopping aid leaflets!

We can organize a school party and ask children to plan the shopping for it: choose what is needed, decide the suitable quantity, compare products and choose the best offers, verify not to spend more than the given budget. Consider also the money spent for travelling to the supermarket.

Pay attention to the calendar for the party-date and offers’ validity and think about perishable goods.

Different groups could work on different supermarket leaflets and decide where to buy what in order to save as much money as possible.

Consider promotional gadgets and points: they worth while or they’re unuseful objects for us or our party? Lots of reasoning and counting and problem solving…all linked to real life!

Today I brought some pinecones .... we count how many bracts (the part that contains pine nuts) are there and how they are arranged .....

Let's make a drawing of what we saw .....

What do you remember ? Think of the arguments that we have studied in class;)

Skills are:
Team work; understand the delivery; Orient themselves in space; create a graph; track between the knowledge possessed those really solve the problem

Now compare your work with that of their classmates .... pinecone was bigger? Smaller? You got different results?

And now ...... have you found a mathematical relationship between the numbers that you obtained by counting?,,,,,,,, Yeah, right! The Fibonacci sequence !!! Even in a pine cone is math !!!

I used this article with my students to face a real world problem, to inform them and discuss with them. At the same time I highlighted the fact that the graphics and the table are really usefull to sum up data and they make them more "readable". Finally I wanted them to understand that all the knowledge provided by the school is going to create part of the culture they are going in their adult life.

According to me we need to begin by needs of the children. It’s means to know the interestes of the students. So the kids can built a house of one bird.
The kids to know geometric shapes can build a bird house plan in 2D on the cardboard.Then they cut the shapes out and make a house in 3D. The kids are engaged, they are happy to make an house for the bird country. Then they can think their house and his shapes.They can know what is the sides, the vertices, the angle and found the perimeter.
Then I can say to use their imagination to make other houses using different shapes.

These are some of the workshop images on symmetries that my class with a third (16 years-old) we realized within "BergamoScienza 2016". A really exciting experience for me but especially for the guys!
The workshop aims at stimulating children to watch symmetries around them: in nature, in art, in everyday objects, in letters and in geometric figures. Divided in small groups, the participants are encouraged to spot line, point and rotational symmetries by using mirrors and sheets of paper.
Mirrors are especially suitable for a playful approach, as they can be used as an axis of symmetry creating simple reflections, or to complete partially drawn figures. With two incident mirrors, the number of reflected images depends on the angle they form; with more mirrors you can make simple optical machines that create astonishing images. Symmetries can also be observed by folding and colouring paper to make flexagons.

In Greece we are familiar to earthquakes. Recently we had a big one. Every year in schools we have simulations about teachers' and students' reactions in case of an earthquake.
So we can show them an image of a seismograph and teach a chapter of geometry.
Ask the students to find the epicenter.
I create an image (see below) or we can project a short video about earthquakes.
The epicenter of an earthquake is a point on Earth's surface directly above the earthquake;s origin. A seismograph can be used to determine the distance to the epicenter of an earthquake. Seismographs needed three different places to locate an earthquake's epicenter. Use the seismographs readings from locations A,B and C to find the epicenter of an earthquake.

The epicenter is 7 miles away from A(-2 , 2,5)

The epicenter is 4 miles away from B(4 , 6)

The epicenter is 7 miles away from A(3 , -2,5). I upload the solution too

The question is: which types of number describe this picture?

I imagine using this picture to talk about rational and irrational numbers. If the rectangle's sides are rational, then the semicircumference's length is equal to an irrational number.

mirjana_jovanovic_ns — 2016-10-29 18:25:58 UTC

- I always use dice and coins for probability.
- Ratio, proportion, similarity: Let the students measure the ratio of sides of A4 paper format, and then A5 format. Is it the same (approximately)? Estimate and calculate the area A0 paper format. Calculate the ratio of sides of A format papers. Are there any other rectangles with the same property....

Some of my students learn music and one of the activities I intent to propose them is to find Maths in a musical score.

I believe they will easily say that there are fractions on a score. I think it´s a good way to explain them where to use the sum of fractions on their everyday life.

This is a pavement of an ancient building in my town, that usually students see when they go to conferences, expositions and other similar activities. Once it was the public library and every student studied at its side.
After showing only the picture on the right, I would ask them: what can you see? is there any geometrical figure? great part of them would answer they can see cubes. Can you calculate the area on the floor occupied by each cube if I only give you one the size of one segment? At first they would answer they can't. Later I will show them the other figure and make them think about what they can know about angles; they would easily get that each rhombus is made up of 2 equilateral triangles and so it is possible to calculate almost everything.

On some stretches of the Italian highways, the average speed is controlled between two points. If the average speed is greater than the maximum allowed, you are fined. Similar methods are used in many countries
The Lagrange's theorem guarantees that if the average speed is greater than the maximum, there was at least an instant in which the limit was exceeded.

What does math have to do with home decorating? In order to figure out what you'll spend, you first have to know what you need. Understanding some basic geometry can help you.
Figuring area: Squares and rectangles

Imagine you're planning to buy new carpeting for your home. You're going to put down carpeting in the living room, bedroom, and hallway, but not in the bathroom. You could try to guess at how much carpet you might need to cover these rooms, but you're better off figuring out exactly what you need. To determine how much carpet you'll need, you'll use this simple formula:

A = L x W

Or in other words, "area equals length times width." This formula is used to determine the area of a rectangle or square. In the floor plan below, all of the floor space (as well as the walls and ceilings) is made up of squares or rectangles, so this formula will work for figuring the area you need to carpet.

Start by figuring the total area of the floor plan. When you're done, you can deduct the area of the bathroom, since you don't want to carpet that room. To figure out the total area of the floor plan, you'll need to know the total length and width. The total length of the floor plan shown above is 12 feet plus 10 feet, or 22 feet. The total width is 7 feet plus 5 feet, or 12 feet. Plug these numbers into your equation to get the total area of the floor plan:

A = 22 feet x 12 feet
A = 264 square feet
The total area of your floor plan is 264 square feet. Now you need to figure out the area of the bathroom so you can deduct it from the total area. The bathroom is 7 feet long and 5 feet wide, so it has an area of 35 square feet. Deducting the area of the bathroom from the total area (264 minus 35) leaves you with 229 square feet to carpet.

Maths in everyday life

More math can be found in the kitchen than anywhere else in the house. Cooking and baking are sciences all their own and can be some of the most rewarding (and delicious) ways of introducing children to mathematics. After all, recipes are really just mathematical algorithms or self-contained step-by-step sets of operations to be performed. The proof is in the pudding!

Working in the kitchen requires a wide range of mathematical knowledge, including but not limited to:

measuring ingredients to follow a recipe

multiplying / dividing fractions to account for more or less than a single batch

converting a recipe from metric (mL) to US standard units (teaspoon, tablespoon, cups)

calculating cooking time per each item and adjusting accordingly

calculating pounds per hour of required cooking time

understanding ratios and proportions, particularly in baking (ex. the recipe calls for 1 egg and 2 cups of flour, then the ratio of eggs to flour is 1:2).

Following a recipe can sometimes be tricky, especially if conversions are necessary. We Americans follow our own set of rules when it comes to most forms of measurement. Conversions make it a bit more difficult to follow recipes from other countries as they most likely use Celsius and the metric system.

Last year, while studying conic sections I brought one of my class to an ice cream shop near our school. We had a good italian ice cream and I asked for some empty cones to explain conic sections using a cutter to show them circle, ellipse, parabola and hyperbole

When I have to explain interest account to my students, I usually show them the credit cards and talk with them about risky using of credit cards.

I would show this picture before I start algebra and equations. This picture emphasises the need to collect like terms, to group together the same teams and that when changing sides they have to change gears, change sign.

The picture is the outcome of an activity I did 2 years ago with 7 years old class. Everything started after I and my pupils had watched a bike competition passed along the road in front of our school (children had lot of fun cheering for the bikers)

Fractions can be used to slide a cake into equal pieces and to share it with your loved ones. :)

One day I ask my children of the 5-th grade to estimate how many children or cars can fit in the school yard or I come to a classroom and i ask if they can calculate how many children must be in this room and if there is some room left for me taking into account that there are 2 m3 for one child) .

Math is everywhere ,if we go to the market we need math,if we go on a trip we need math,if we have a problem we need math.

Lisbon tours are traditionally paved with small blocks of limestone, basalt and other materials. The knapsacks take advantage of the limestone diameters system, with the aid of a hammer, to make small adjustments in the shape of the stone. Diaclases occur in all types of rocks, particularly hard rocks, and are no more than fractures along which there was no considerable movement. These fractures are formed by rupture as a result of a stress field applied to the rock material. They intersect in several directions, some of them leading to a network of fractures that facilitates the separation of the rock into blocks.
Knitters use molds to mark zones of different colors, repeating these motifs in a linear sequence (friezes) or in the two dimensions of the plane (patterns). The geometry of the XX century proves that there are a limited number of possible symmetries in the plane: 7 for the friezes and 17 for the patterns. A study of young Portuguese students, encouraged by the Portuguese Society of Mathematics (www.spm.pt), registered 5 types of friezes and 11 types of patterns on the Lisbon sidewalks. A project is underway between the Municipal chamber ofLisbon and the Portuguese Society of Mathematics, which aims to increase the geometric richness of the Lisbon sidewalk, completing it with the missing types of symmetries.
Step on the math and have fun discovering the symmetry of the rides you tread.

A topic where students can understand the connection between maths and real world is Operational Research.
For example I use the following video when I introduce the topic on O.R. in a CLIL lesson

I studied with my students Batman equations, to show them how to use equations and disequations to calculate domains of the functions. It has been a very interestingwork .

My students have done the weighing of the ingredients of a cake recipe, by choice, on groups, and making home, with these amounts, the actual cake.
