About this method

Units and parts

Cut one amount into equal shares. One number tells you what a share is worth.

In this one. Choose the number of units so that every fraction in the question lands on whole units — then each "fraction of" is just counting boxes, and the unknown group is the leftover.

In allone share

How to spot it

A single amount is split by a ratio, a fraction or a percentage. One extra number gives you the leftover, the difference, or the value of one share.

Common mistake

Children match the given number to the wrong number of shares, using the whole bar when the number covers only the leftover or the difference between two people's shares.
