About this resource
Description
Before a child can add, they have to see that a number is made of smaller numbers. Six is two apples and four more apples. Ten is five and five. Using this Decomposing Numbers Assessment Worksheet, Kindergarten students look at a row of apples split into two sides, count each side, and write the two numbers that make the whole. Breaking a number apart this way is the foundation of every addition fact a child will learn, and it is exactly what Kindergarten standards ask students to show.
The Decomposing Numbers Assessment Worksheet is a two page printable. Page one holds four picture problems for the numbers 6, 9, 7 and 10. Each problem shows a group of apples on each side of a plus sign, with the total already printed in the last box, so the child counts the two sides and fills in the two missing parts. Page two is the answer key. Print it, hand out counters or real snacks, and let students build the same numbers with objects before they write. It works as a quick check at the end of a unit or as a warm up on any morning.
What’s Included
- A two page PDF worksheet built for Kindergarten
- Four picture problems that decompose 6, 9, 7 and 10 into two parts
- Big, clearly spaced apple pictures a young child can count one at a time
- Large answer boxes sized for beginning handwriting
- A complete answer key on the final page
Three Reasons This Helps Kids
- Counting a picture and writing the matching number connects what a child sees to the symbols they write, which is how number sense actually forms.
- Seeing that 5 and 5 both make 10, and that 6 and 3 make 9, gives children the number pairs they will lean on for mental addition later.
- Every problem has one correct pair of numbers, so a teacher can score it quickly and see at a glance which numbers a child still needs to practice.
Ideas for Teachers and Parents
- Use this kindergarten addition worksheet as a pre test, then again two weeks later to show growth.
- Give each child ten counters and ask them to find a different way to break the same number apart.
- Cover one side of the apples and ask how many are hiding, which turns the page into a missing addend game.
- Send it home as homework with a note asking families to count snacks the same way at the table.
