Teaching the concept of fractions
Age of students:
- 8-10 years old
- According to the size of the class
Different sized paper plates, markers/felt pens or colouring pencils/crayons
Description of the tool:
- Children watch the video Peg + Cat The Pizza
Problem by Jennifer Oxley
- Discuss with them the different pizza toppings which Pete and his friend put on their pizza.
- What do they notice about the shape of the pizza?
- Divide the class in small groups and give each group a large paper plate each. Tell them that now it is their turn to make pizza.
- Ask them to pretend this is their pizza base, so they should colour it in red.
- Give them 4 small paper plates each and ask them to colour one orange, one pink, one red and one green.
- Ask them to cut the pink plate in half, the red one in 4 pieces, the orange one in 3 pieces and the green one in 8 pieces.
Therefore – Pink = 1/2
- Red = 1/4
- Orange = 1/3
- Green = 1/8
- Discuss with them what they mean
In groups children experiment with mixing and matching the plates. Imagine these are the ingredients they will be putting on their pizza.
- Therefore one group might have ¼ of the red
- plate and ½ of the pink plate on the pizza
base. The paper plates symbolising pizza
- Red could be peperoni or tomatoes, pink could be
sausages or ham, yellow could be cheese and green could be peas.
- Allow the children to experiment with the different fractions and equivalencies.
As a conclusion to the lesson, children could watch the youtube video Pete the cat and the perfect pizza. This could be followed by a comprehension test.
Ask the children to write an exit note and stick it
on the board.
