About this resource
Description
Knowing which two numbers go together to make a total is the heart of early addition, and this Matching Number Pairs Worksheet turns that idea into a quick sorting game. First graders who can see at a glance that 3 and 6 make 9, or that 4 and 6 make 10, stop counting on their fingers and start recalling facts. Sums of nine and ten matter most of all, because ten is the number students later use to break apart every harder problem they meet.
This printable Matching Number Pairs Worksheet gives students a box of eight number pairs and two labeled columns, one headed 9 and one headed 10. Students add each pair, decide which sum it makes, and write it on a line in the matching column. The pairs in the box are deliberately mixed up, so a student cannot sort them by position and has to add every one. A short second section follows with three missing number equations, including 10 + 0 = 10, so students also meet the idea that adding zero changes nothing. This addition to ten worksheet works well as morning work, a math center, or a fast check before a unit test.
What’s Included
- One printable page with a box of eight number pairs
- Two labeled sorting columns, one for sums of 9 and one for sums of 10
- Four roomy writing lines in each column
- Three missing number equations at the bottom of the page
- A complete answer key
Three Reasons This Helps Kids
- Sorting by sum makes students add on purpose instead of copying an answer.
- Sums of 9 and 10 sit right beside each other, so students notice how close the two totals are.
- The missing number equations ask the same facts backward, which is how fact fluency is really tested.
Ideas for Teachers and Parents
- Work the first pair together out loud before students begin on their own.
- Give students counters or a ten frame to build any pair they are unsure of.
- Ask students to add one more pair of their own to each column when they finish.
- Read the sorted column aloud as a chant to build recall.
