What does this page ask my child to do?

It asks the child to build the numbers 18, 13, and 12, then write how many tens and ones each number has.

How should I introduce the first problem?

Say the number together, point to the model, then ask how many tens there are before counting the ones.

Is this worksheet right for a 6-year-old?

It is a good match for many 6-year-olds who can count to 20 and are starting to learn teen-number place value.

What should I do if the tens and ones get switched?

Pause and use one number at a time, covering part of the page if needed so the child can focus on the tens first and the ones second.

Can we reuse this page after it is finished?

Yes, you can place it in a dry-erase sleeve or print another copy and have the child explain each answer out loud.

Learning Outcomes

Teen numbers → Identify tens and ones → Record 18, 13, and 12 as 1 ten with leftover ones.

Place value models → Connect digits to quantities → Explain what the tens digit and ones digit show in each number.

Writing fields → Practice number representation → Fill in tens and ones counts after looking at each model.

1st Grade Math

English Counting & Number Sense Kindergarten Readiness 6 years old

Kids often stall when a number has two digits because they are still learning what each digit is doing. This page keeps the task small and concrete: build 18, 13, and 12, then use the writing fields to show how many tens and ones are in each number.

This is a good fit when a first grader can count to 20 and is ready to look more closely at teen numbers. The clear models give a starting point, so the work is not just copying numerals. The child can see that 18 has 1 ten and 8 ones, 13 has 1 ten and 3 ones, and 12 has 1 ten and 2 ones.

Sit together for the first problem and say the number out loud before writing. Ask, “How many tens?” and “How many ones?” Keep the pace gentle. If the ones place gets mixed up, cover the tens for a moment and count only the ones. For a warm-up before this page, counting and drawing circles gives extra one-by-one counting practice without adding place value yet.

After finishing, read each completed line back in a full sentence, such as “18 is 1 ten and 8 ones.” That quick read-back helps connect the model, the written number, and the place value words. If the child is comfortable, follow with finding missing numbers to practice number order around teen numbers in a different way.
