This challenging worksheet pushes kindergartners to think more carefully about number order across the full 0 to 20 range. Part A offers four multiple-choice questions, asking which number comes right after 15, the missing number in 8, 9, ___, 11, what comes just before 20, and a count backward from 14, 13. Children must compare four answer choices and pick the best one.

Part B is a five-question fill-in-the-blank set including 2 more than 16, the number between 4 and 6, and counting on from 11, 12, 13. Switching between choosing and writing answers builds the flexible counting and one-more, one-less thinking kindergartners will rely on for early addition.
