Mrs Lacey wanted to make some cakes for 3NL. However the ingredient list was written in fractions!
Baking Investigation-
Fruit and chocolate
flapjacks
Here are the ingredients I bought:
Oats
– the bag weighs 500g
Butter
– the packs weigh 240g
Raisins
– the bag weighs 120g
Chocolate
chips – there were 56 in the bag
Cherries
– there were 60 in the bag
Flour
– the bag weighs 1kg
Sugar
– the bag weighs 1kg
Here are the amounts of each ingredient that I need to use:
Oats
– I need 3/5 of the bag
Butter
– I need 1 ½ packs
Raisins
– I need 5/6 of the bag
Chocolate
chips – I need 5/8 of the bag
Cherries
– I need 1/12 of the bag
Flour
– I need 1/10 of the bag
Sugar
– I need 3/20 of the bag
The children came to the rescue and did a fraction investigation to solve Mrs Lacey's problem and work out the ingredients she needed.
We then got to eat the delicious cakes and biscuits - Mmmm....
