Teaching tips and what to try next

Fits kindergartners who count small groups reliably and are moving toward 20. The circle pictures are the real test, since there is no natural start, so a pencil tick on the first dot saves a lot of recounting. Afterward, try sorting and counting in Sort and Count Shapes or practice reading groups quickly with Counting Tally Marks to 20.

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

Counting a neat row of dots is one thing, but counting dots arranged in a circle takes a plan. Kindergartners are expected to count as many as 20 objects arranged in a line, a rectangular array or a circle, and to know where they started so nothing gets counted twice. This kindergarten worksheet gives practice with all three arrangements.

The page has eight pictures. Three show dots in a straight line, from 6 to 12 dots. Three show dots in rows and columns, like an egg carton, with 2 to 4 rows. Two show dots placed around a circle, with 8 to 20 dots. Next to each picture is a box where children write how many dots they counted. The pictures are mixed on the page, so children have to choose a counting plan each time. Each of the ten versions has new pictures and its own answer key.

How to use it: for the lines, have your child touch each dot as they say a number. For the arrays, count one row at a time, left to right. For the circles, the trick is to mark the starting dot with a small pencil tick and stop when you get back to it. Ask your child to count each picture twice and check that both counts match.

The answer key gives the number of dots in each picture. For ten-frame counting, try our Count to 20 With Ten-Frames worksheet. For smaller groups, try our Counting Objects to 10 worksheet.
