Addition Quiz for Kids: Free Online Quiz, Timed Test and 100 Practice Questions

An addition quiz is a short set of adding questions that checks how quickly and correctly a child can find a sum. Use the free addition quiz below: pick a level from Pre-K to 3rd grade, try a 1-minute timed test, see instant feedback and stars, and print a quiz with an answer key.

Every addition quiz above is made fresh each time, so your child never gets the same questions twice. It works on phones, tablets and computers, with no sign-up and no download.

How Does This Addition Quiz Work?

The tool turns addition practice into a short game. Kids answer one question at a time and get a score at the end. Here is how to use it:

• Pick a level: ten levels go from adding within 5 with pictures up to 3-digit addition for 3rd grade.
• Pick a question type: “Find the sum” (4 + 3 = ?), “Missing number” (4 + ? = 7) or a mix of both.
• Pick the length: 5, 10 or 20 questions, or the 1-minute timed test to see how many addition problems your child can solve in 60 seconds.
• Answer and learn: a correct answer turns green. A wrong answer turns red and the correct sum is shown straight away, so kids learn from every mistake.
• See the score: kids get a score, up to three stars and a short “practise again” list of the facts they missed.
• Print it: the print button makes a 20-question addition test on paper with a separate answer key page. Choose “Save as PDF” in the print window to keep it.

Which Addition Quiz Level Is Right for Your Child?

Start one level below where you think your child is. An easy first quiz builds confidence, and you can move up as soon as they score three stars. The levels follow what kids usually learn in each grade, based on the Common Core standards for operations and algebraic thinking.

Quiz level	Grade	What kids practise	Example
Adding within 5 (with dots)	Pre-K	Counting objects to find a total	2 + 1 = 3
Adding within 10	Kindergarten	Basic addition facts to 10	6 + 3 = 9
Make 10	Kindergarten	Pairs that make ten (number bonds of 10)	7 + 3 = 10
Adding within 20	1st grade	Addition facts to 20, counting on	8 + 7 = 15
Doubles and near doubles	1st grade	Mental math with doubles	6 + 7 = 13
Adding three numbers	1st grade	Grouping numbers to make it easier	4 + 6 + 3 = 13
Adding tens	2nd grade	Place value with tens	40 + 30 = 70
2-digit, no regrouping	2nd grade	Adding ones and tens separately	34 + 25 = 59
2-digit, with regrouping	2nd grade	Carrying a ten	38 + 47 = 85
3-digit addition	3rd grade	Adding hundreds, tens and ones	356 + 278 = 634

39 + 44 = ?	83	57 + 35 = ?	92
68 + 24 = ?	92	45 + 45 = ?	90

The first eight questions in this addition quiz need no regrouping. The rest ask kids to carry a ten, which is the main 2nd grade addition skill.

Addition Quiz for Grade 3 (3-Digit Addition)

Question	Answer	Question	Answer
120 + 230 = ?	350	305 + 402 = ?	707
214 + 163 = ?	377	341 + 258 = ?	599
156 + 127 = ?	283	238 + 145 = ?	383
409 + 276 = ?	685	367 + 218 = ?	585
185 + 146 = ?	331	274 + 159 = ?	433
358 + 267 = ?	625	476 + 385 = ?	861
299 + 301 = ?	600	520 + 280 = ?	800
645 + 238 = ?	883	712 + 189 = ?	901
463 + 379 = ?	842	588 + 256 = ?	844
395 + 405 = ?	800	250 + 250 = ?	500

In a 3rd grade addition quiz, ask kids to estimate first. If 356 + 278 is “about 600”, an answer of 934 is clearly wrong. This habit builds strong math skills.

Word problems help kids see where addition is used in real life. Ask your child to say the number sentence first, such as “4 + 3 = 7”, before giving the answer.

What Addition Strategies Help Kids Answer Faster?

Speed in an addition quiz does not come from rushing. It comes from knowing smart strategies, so kids can find a sum in their head instead of counting every object. Teach these one at a time:

Strategy	How it works	Example	Best for
Counting on	Start with the bigger number and count up	8 + 3: say “8… 9, 10, 11”	Pre-K and K
Make 10	Break a number to make a ten first	8 + 5 = 8 + 2 + 3 = 13	K and 1st grade
Doubles	Learn doubles by heart	6 + 6 = 12	1st grade
Near doubles	Use a double, then add 1	6 + 7 = 6 + 6 + 1 = 13	1st grade
Number line	Jump forward on a line	25 + 10: jump from 25 to 35	1st and 2nd grade
Place value	Add tens, then ones	34 + 25 = 50 + 9 = 59	2nd grade
Regrouping (carrying)	When ones make 10 or more, carry a ten	38 + 47: 8 + 7 = 15, write 5, carry 1	2nd and 3rd grade

If your child struggles with “make 10”, spend a few days on number bonds first. For 2-digit addition, a strong grip on place value makes regrouping much easier to understand.

Addition Facts Table: Sums from 0 to 10

This addition facts table shows every basic addition fact from 0 + 0 to 10 + 10. Find one number in the left column and the other in the top row. The box where they meet is the sum. Kids who know these facts by heart do much better in any addition test.

+	0	1	2	3	4	5	6	7	8	9	10
0	0	1	2	3	4	5	6	7	8	9	10
1	1	2	3	4	5	6	7	8	9	10	11
2	2	3	4	5	6	7	8	9	10	11	12
3	3	4	5	6	7	8	9	10	11	12	13
4	4	5	6	7	8	9	10	11	12	13	14
5	5	6	7	8	9	10	11	12	13	14	15
6	6	7	8	9	10	11	12	13	14	15	16
7	7	8	9	10	11	12	13	14	15	16	17
8	8	9	10	11	12	13	14	15	16	17	18
9	9	10	11	12	13	14	15	16	17	18	19
10	10	11	12	13	14	15	16	17	18	19	20

• Look for patterns: each row goes up by one, and the doubles run in a diagonal line.
• Turn-around facts: 3 + 5 and 5 + 3 give the same sum, so kids really only need to learn about half the table.
• Learn in small groups: master +0, +1 and +2 first, then doubles, then make 10, then the rest.

What Is a Good Score on an Addition Timed Test?

An addition timed test checks fact fluency, which means answering quickly and correctly. Use these goals for the 1-minute timed test as a friendly guide, not a strict rule. Every child learns at their own pace.

Grade	Quiz level	Good 1-minute goal	Next step
Kindergarten	Adding within 10	8–12 correct	Move to make 10
1st grade	Adding within 20	15–20 correct	Try doubles and three numbers
2nd grade	2-digit, no regrouping	10–15 correct	Move to regrouping
3rd grade	3-digit addition	6–10 correct	Try word problems

The best goal is beating your own score. Write today’s result on a sticky note and try to add one or two more correct answers next week.

Common Addition Mistakes and How to Fix Them

Mistake	Example	Quick fix
Counting the first number again	5 + 3: counts “5, 6, 7” and says 7	Say the first number, then count on: “5… 6, 7, 8”
Forgetting to carry	38 + 47 = 75	Circle the ones first; if they make 10 or more, write the 1 above the tens
Lining up digits wrongly	45 + 3 written as 45 + 30	Use squared paper or a place value chart
Guessing when rushed	Random answers on a timed test	Go back to untimed practice for a few days
Mixing up + and −	7 − 2 answered as 9	Say the sign out loud before answering

Most mistakes in an addition quiz are small habits, not a lack of ability. Fix one habit at a time and the score will follow.

From My Classroom

In my eight years of teaching, addition was where many of my slow learners first lost their confidence in math. They could count objects, but timed addition tests made them freeze.

What helped most was taking the pressure off. We began with addition quizzes of only five questions, all at a level they could already do, and I praised effort before speed. Once they felt safe, I taught one strategy at a time, starting with counting on and then making ten.

I often paired a confident child with one who was still learning, and both of them improved as they explained their thinking to each other. Only when a child could answer comfortably did we try a timed test, and even then the goal was to beat their own score, never a classmate’s. That is why this addition quiz shows the right answer straight away and lets kids practise the facts they missed.

How Can You Make Addition Practice Fun?

• Dice addition: roll two dice and add the numbers. The first to reach 50 wins.
• Card game: flip two playing cards (ace = 1, picture cards = 10) and race to say the sum.
• Shopping game: give items prices up to 20 cents and let kids add up the bill.
• Star chart: collect the stars from each quiz and give a small reward at 20 stars.
• Swap roles: let your child quiz you and catch your “mistakes”.
• Hundreds chart jumps: use a hundreds chart to add tens by jumping down a row.

What Should Kids Practise After an Addition Quiz?

Score	What it means	Next step
90–100% (3 stars)	Facts at this level are strong	Move up one level or try the 1-minute timed test
70–89% (2 stars)	Almost there	Practise the missed facts, then take a new addition quiz
40–69% (1 star)	Still learning	Use objects, fingers or a number line and stay at this level
Below 40%	Level is too hard right now	Move down one level and build confidence first
