How to use the number sense practice
- Sit with your child. For kindergarten, read each question together or tap Read to me.
- Pick one skill. If you are not sure, start with counting the objects and move down the table.
- Let them point. Touching each object while counting stops double counting.
- Read the hint when an answer is wrong. It shows a quicker way, like counting by 5s along a full row.
- Stop at 10 questions. Short, happy rounds beat long ones. Come back tomorrow for the next round.
What number sense means
Number sense is a feel for numbers. A child with good number sense knows that 8 is close to 10, that 8 is 5 and 3, and that 18 is 10 and 8 more.
It grows from counting real things, seeing patterns like ten frames and dice, and talking about numbers. These skills make adding and subtracting much easier later.
Pictures in the questions
Most questions are pictures. Dots, stars and squares are for counting. Ten frames are two rows of 5 squares with counters in them, the way many classrooms show numbers to 10.
Number bonds show a whole in the top circle and two parts below it. The hundreds chart questions show a small piece of the chart with one number hidden.
How answers are marked
- Numbers are typed into one box. On a phone, a big number pad appears.
- Choices, such as even or odd, more or fewer, and ordinal numbers, use big buttons.
- Quick look questions ask your child to see the number without counting. Encourage a fast guess, then check.
- Estimating asks for a sensible guess, like about 20, not the exact count.
A sensible order for practice
Number sense builds from kindergarten to grade 2. This order follows the US Common Core and the NCERT books:
- Count the objects, ten frames and quick looks (K.CC.B.4, K.CC.B.5): how many, to 10 and then to 20.
- More and fewer, and number bonds (K.CC.C.6, K.OA.A.3): comparing groups and splitting numbers.
- Teen numbers and counting to 120 (K.NBT.A.1, 1.NBT.A.1): 10 and some more, and the counting sequence.
- Number line and hundreds chart (1.NBT.C.5, 2.MD.B.6): where numbers live, and 10 more or less.
- Skip counting, even and odd, and patterns (2.NBT.A.2, 2.OA.C.3): the first steps towards multiplication.
When a skill won’t stick
- Counting the same object twice: move each object to one side as it is counted, or cross it off on paper.
- Getting stuck at 29 or 39: practice “crossing a ten” on the hundreds chart. After 29 comes 30, the next ten.
- Writing 41 for fourteen: show 14 as a full ten frame and 4 more. The ten comes first.
- Mixing up more and fewer: line the two groups up and match them one to one. The group with some left over has more.
- Guessing on number bonds: use 10 real objects and split them between two hands.
A 10-minute routine
- Minutes 1–2: count something real together: stairs, spoons or toy cars.
- Minutes 3–8: one round of 10 questions on the current skill.
- Minutes 9–10: one pattern on the hundreds chart, like counting by 10s.
Number sense by grade
| Grade | What children practice | Standard |
|---|---|---|
| Kindergarten | Count to 100 by 1s and 10s, count objects to 20, compare groups, bonds to 10 | K.CC, K.OA.A.3 |
| Grade 1 | Count to 120, teen numbers, 10 more and 10 less | 1.NBT.A.1, 1.NBT.C.5 |
| Grade 2 | Skip count by 5s, 10s and 100s, even and odd, number lines to 100 | 2.NBT.A.2, 2.OA.C.3, 2.MD.B.6 |
In India, number sense runs through the NCERT Joyful Mathematics books in classes 1 and 2, with counting, numbers to 99 and patterns.

How can my child practice number sense online for free?
Use the practice tool at the top of this page. Pick a skill, such as counting objects or ten frames, and answer 10 questions one at a time. Every answer is marked straight away.
My child can’t read yet. Can they still use it?
Yes. Tap Read to me and the question is read aloud. Most questions are pictures with a number to type or a big button to tap.
Which skill should my child start with?
Start with counting the objects and ten frames. Then move on to teen numbers, counting to 120, before and after, and number bonds.
What is number sense?

What grade is this practice for?
Kindergarten to grade 2. Counting, ten frames and quick looks suit kindergarten. Teen numbers, counting to 120 and number bonds suit grade 1, and skip counting and number patterns suit grade 2.
Can teachers link to one skill?
Yes. Add ?skill= to the address, for example /number-sense/practice/?skill=frame for ten frames. Every child gets their own random questions, with no login.
