Number Sense Practice & Worksheets
Free, interactive practice for the first math skills — counting, skip counting, number bonds and even/odd — grades K–2. Big tap-to-answer buttons, picture models, and a printable worksheet for every skill.
Practice all of number sense
This mixed review moves between counting, skip counting, number bonds and even/odd so the youngest learners build all four together.
The foundation of everything else
Number sense is where math begins. Counting builds the number order; Skip Counting turns that into the patterns behind the times tables; Number Bonds make the make-a-ten trick automatic for fast addition; and Even & Odd starts the thinking that leads to multiples and division. A few minutes a day here pays off across every later topic.
By grade
- Kindergarten: counting to 100 and bonds to 10.
- Grade 1: skip counting and even/odd.
- Grade 2: skip counting by 2s and 5s, bonds to 20 and 100.
How to help at home
Keep it short and playful. Count everyday things aloud (stairs, toys), ask “what comes next?”, and quiz the bonds to ten in spare moments. The picture models — number cards, ten-frames and paired dots — let a child see the answer rather than just hear it.

Frequently asked questions
Is this practice free?
Yes — all practice and worksheets are free, no sign-up, and no ads inside the practice.
What is number sense?
An early, flexible feel for numbers — their order, how they break apart and combine, and patterns like odd and even. It underpins all later arithmetic.
Where should my child start?
With counting, then number bonds and skip counting — they lead straight into addition and the times tables.
Why are number bonds to ten important?
They power the make-a-ten strategy, which makes adding and subtracting within 20 fast and reliable.
Is this suitable for a kindergartener?
Yes — the easy levels use large tap-to-answer buttons with no time pressure.
Can I print worksheets?
Yes — each skill page has a print button for a fresh 20-question sheet with an answer key.
