Proportion and ratio

Proportion of oranges to apples

Understanding and working with proportion and ratio are core maths skills that your child will be taught in KS2, and probably at some stage they'll come home with homework to help reinforce learning in this area.

Proportion tells us about a portion or part in relation to a whole whilst a ratio compares values, telling us how much of one thing there is compared to another thing. These are topics that children only start learning about in Year 6 and you might well be asked to help your child solve problems involving proportion, scale a recipe up or down, or present a ratio problem using different methods.

Once you've read our guides and are confident in your own understanding of the concepts, try printing out some teacher-created worksheets to help your child solve proportion problems and solve ratio problems. Make learning fun by solving proportion puzzles, play a game of Proportion dominoes or mix some evil potions (but make sure you get the ratio of ingredients right).

Ratio and proportion questions may well pop up in KS2 SATs, so make sure your child has mastered these tricky skills and watch their confidence grow.
