Take one cookie off a plate of five and most five-year-olds know at once that something changed, yet saying “now there are four” takes a little more. This kindergarten one less worksheet works on that step. Each of the three rows starts with a model: 5 yo-yos, then 4 yellow horns (the page calls them trumpets), then 3 umbrellas. Below each model, three boxes hold different amounts, and your child ticks the box that has one less. The PDF has two pages, the worksheet and its answer key.
