Teaching tips and what to try next

Made for kindergartners who can count to 20 from 1 and are learning to start the count anywhere. Hopping along a number path taped to the floor, one step back for before and one step forward for after, turns the idea into movement. When the teen rows feel easy, try Counting Forward from Any Number or the bigger range in Before, After and Between Numbers to 120.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Kindergartners learn to count forward from any number, not just from 1. Knowing that 14 comes right after 13, or that 8 comes just before 9, shows that a child understands the counting sequence instead of reciting it from the start. This kindergarten worksheet practices numbers that come before, after and between, all within 20.

The page has three short parts with six rows each. In the Before part, a number sits in a box and children write the number that comes just before it. In the After part, they write the number that comes just after. In the Between part, two numbers sit on either side of an empty box, and children fill in the number in the middle. Every number on the page is from 1 to 20, and the rows mix small numbers with teen numbers. Each of the ten versions has new rows and its own answer key.

How to use it: say each row out loud together, like a short counting chant: "12, 13." For before, it can help to count up from a smaller number until you reach the number in the box. A number line or a strip of paper numbered 1 to 20 lets your child point and check. Keep the first few sessions short and praise careful counting.

The answer key shows every missing number. For more counting on, try our Missing Numbers 1-20 worksheet. For one step up or down, try our One More, One Less worksheet.
