Objective:

Teaching the concept of fractions

Time needed:

• 45 minutes

Age of students:

• 8-10 years old

Groups size:

• According to the size of the class

Materials needed:

• 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
  ingredients.
• 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.
