Make the Number

Kindergarten·K.OA.A.3

Find pairs of numbers that add up to the target. Tap a number, then tap its partner — and watch the pairs link. Aligned to Common Core K.OA.A.3 — decompose numbers less than or equal to 10 into pairs in more than one way.

About this activity

A target appears — say 5 — and children find the number pairs that add up to it, like 1 and 4 or 2 and 3, tapping one number, then its partner, to link the pair. It's an interactive Kindergarten number-matching game that plays right in the browser — no install, no account.

The big idea is that one number can be made in more than one way. With a target of 7, children might link 0 and 7, then 3 and 4, discovering that the same total has several partner pairs. Because the activity asks for the pairs that make the target rather than a single right answer, it quietly builds the part-part-whole sense that all later addition rests on.

It is aligned to Common Core K.OA.A.3 — decomposing numbers less than or equal to 10 into pairs in more than one way. No timer, no score — just calm, playful practice.

What's inside this activity

  • Designed for Grade K learners (ages about 5–6)
  • Common Core strand: Operations & Algebraic Thinking
  • Aligned to Common Core standard K.OA.A.3

How to play

Look at the target number for the round, such as 6.

Tap a number, then tap its partner that adds up to the target, and watch the pair link.

Find all the pairs that make the target — there is no timer and no score, so take your time.

What your child practices

  • Find two numbers that add up to a target up to 10
  • Discover more than one pair that makes the same number
  • Build part-part-whole understanding of small numbers
  • Match a number to its partner that completes the total

Learning goals
