Maths with Lego Bricks

Addition,substraction, multiplication and division are easy  if you can use Lego bricks.

Maths lesson in grade four.

Playing with mathematics.

Here are some games to motivate students with mathematics.

1. Addition using LEGO. 

2 tens and 6 units + 1 ten and 5 units...

= 3 tens and 11 units

then, we group the units: 4 tens and 1 unit.

2. Paper fortune teller + dice.

We write multiplications on the fotune teller paper and roll the dice...

3. Plastic cups. 

They are perfect to represent HUNDREDS, TENS and UNITS. 

4. Mental calculation.

I use popsicle sticks to match a pair of students...

I say a number, then roll the dice and we add it or substract it. 

The fastest student passes to the next round.

Maths Club

Fourth grade students learn how to build solids that meet certain conditions. They try, analyse different solutions, draw conclusions and generalize - all this with Lego blocks during maths club activities.

Fractions

Learning fractions can be sweet and funny. Fourth grade students are doing simple calculations with fractions using chocolate squares and then Lego blocks.

From Least to Greatest

Today we have made a very fun game in math class, in second grade.

  

First, in pairs, we have measured our partner.

Second, we have written down on a paper the centimetres that we exceed one metre, for example, if you are 1 metre and 25 centimetres tall, you write down 25 on a piece of paper. 

Third, we have used the numbers written on the papers to order ourselves from "least to highest". .

Fourth, we have reflected on the result: 

the numbers were well ordered, however, we were not properly ordered by height. Surely we have not measured our partners well.

Disassembling Tens

In the pictures you can see second grade students working in groups of four: they are using Lego in order to assemble and disassemble numbers in UNITS AND TENS,

TASK 1: 

Student number 1 thinks of a number: i.e. 34

Student number 2 represents the number with Lego blocks. 

                      In this example, he needs three towers of ten  (TENS) and four units.

Student number 3 disassembles one of TENS.

Student number 4 says how many TENS and UNITS there are.

                      In this case, there are 2 TENS and 14 UNITS.

TASK 2: 

Student 1 thinks of a number with TENS and UNITS.

Student 2 thinks of another number with TEN and UNITS.

Student 3 makes the ADDITION.

                      He must bear in mind that if the number of units is bigger than ten, he will have to         assemble a new tower. 

Student 4 says the result, 

GEOMETRIC BODIES

Today, in second grade, we have worked collaboratively. The challenge we were asked was how to convert

GEOMETRIC SHAPES

into geometric bodies.

It is a very difficult  to turn a flat shape into a three-dimensional body

First, draw the flat shape. Then, we took a geometric body and thought about the relationship between flat shape and geometric body. And finally, we try to make bodies in three dimensions. For example, you can get a cube (geometric body) with six squares (flat figure).

Here you have the development of some geometric bodies:

Geometric shapes

Today, I have worked with my students geometric figures in a fun way. We made groups and each group had a rubber band that they used to create the figure, each of the students was a vertex.

LEGO Maths

 During this lesson students learnt  by fractions, they had fun creating some tasks given my the teacher. Others had to create their own . They studied more by this tast rather than by paper task.
