How to use these worksheets
Short and often beats long and rare: one sheet, or even half a sheet, a few times a week is plenty. Let your child use counters, fingers or a number line at first, then check the answers together with the answer key and talk about any mistakes. Facts that were tricky are worth revisiting a few days later.
