Fraction games

Frosty fractions - game for 2 players - add fractions (halves, quarters, eighths) by converting fractions to those with common denominator. If the answer is an improper fraction it needs to be converted to a mixed number.

Melvin's make a match - match fractions to pictures - they start easy then get harder including equivalent fractions.

Dolphin racing - choose the biggest fraction to race your dolphin and move it the furthest each go (2 levels)

Tug team fractions - compare fractions using <, > and =

Dirt bike proportions - play with up to 4 player (you join a game or create one for others to join) - equivalent fractions

Ratio blaster - finding equal ratios

Bridge builders - use what you know about equivalent fraction etc to help fill the gaps in the path (it gets harder!)

Triplets - match equivalent fractions and pictures of fractions (each round gets harder!)

Escape from fraction manor - solving fraction puzzles

Spring flowers - a game for 1 or 2 player - using halves, quarters and eighths

Maths in the kitchen

Recipe Maths

There is lots of maths that can be done when using recipes and baking:

1. Weigh ingredients

2. Calculate quantities e.g. If you wanted to make twice as many flapjacks, how much butter would you need? How much does the oats and sugar weight altogether?

3. Calculate ratios e.g. What is the ratio between the sugar and the butter?

4. Use time e.g. If I put the flapjacks into the oven at 4:30, what time will they be ready?



Fruit Kebabs

1. Observe and copy – Make a fruit kebab the same as another one.

2. Repeated patterns – Make or continue a fruit pattern on the kebab.

3. Fractions – What fraction of the kebab is strawberry? Make a fruit kebab where half is grapes etc.

4. Ratio – What is the ratio of orange to melon? Etc.

5. Proportion – What proportion is strawberry? Etc.

6. Multiplication – How many grapes would you need for 5 kebabs? Etc.

7. Subtraction – If I eat 3 bits of fruit how many will I have left? Etc.
