Identifying & Counting to 20 is a free printable kindergarten mathematics worksheet that helps students identify missing numbers in counting sequences from 1 to 20. The 20-item worksheet includes 18 multiple-choice questions and 2 fill-in-the-blank questions, with examples such as finding the number between 15 and 17 or completing a sequence that begins with 13 and 14. Students use the numbers around each blank to determine the next or missing number, strengthening one-to-one counting, number order, and recognition of consecutive numbers. The varied response formats give teachers a quick way to check whether students can apply counting skills independently rather than only recite numbers aloud. The worksheet includes a complete answer key and is suitable for kindergarten practice, classwork, review, or a short formative assessment.

FAQs

What does the Identifying & Counting to 20 worksheet cover?

This kindergarten worksheet focuses on identifying missing consecutive numbers in sequences up to 20. Students solve 18 multiple-choice items and 2 fill-in-the-blank items, using the numbers before and after each blank to determine the correct number.

How can I use this worksheet to teach counting sequences to 20?

First, model how to count forward and use a number line to locate a missing number between two known numbers, such as 15, __, 17. Then have students explain why the missing number comes next before completing the multiple-choice items, and use the two fill-in-the-blank sequences as a brief independent check.

What mistakes should I watch for when students complete this worksheet?

Students may choose a number already shown in the sequence, skip a number when counting forward, or select the number after the missing value instead of the value itself. In the fill-in-the-blank items, watch for students who can recognize an isolated number but do not yet connect consecutive numbers such as 12, 13, 14.

How do I assign and grade this counting worksheet?

On Wayground, assign Identifying & Counting to 20 as a printable PDF or as a digital quiz, and use its complete answer key to check the 18 multiple-choice and 2 fill-in-the-blank responses. Printable submissions can also be graded by scanning student work with the Wayground for Teachers app.

How can I differentiate this worksheet for my students?

Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the number sequences and answer choices are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language when those options support students completing the counting and fill-in-the-blank items.
