KS1 Maths Quiz - Year 2 Calculation - Addition (Questions)

This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 6 and 7 in year 2. Specifically this quiz is aimed at the section dealing with addition of numbers including: a two-digit number and ones, a two-digit number and tens, two two-digit numbers and three one-digit numbers.

Calculating totals means looking at the numbers in an addition calculation and thinking about a sensible way to add them together. When three one-digit numbers are to be added, for example in the calculation 5 + 7 + 5, it might make sense to add the 5 and 5 to make 10, before adding on the 7. If two two-digit numbers are to be added, such as 12 + 13, adding the 2 and 3 to make 5 and then adding the two tens to make 20 might be wise. The same sort of logic applies when adding a two-digit number and a one-digit number. Recognising that additions can be completed in any order could help with this.

KS1 Maths Quiz - Year 2 Calculation - Addition (Answers)
1. What is 10 + 9 + 10?
 [ ] 11 [ ] 39 [ ] 19 [x] 29
Adding the 10 and 10 up first, then adding the 9 might have helped
2. What is the total of 2, 15 and 3?
 [x] 20 [ ] 19 [ ] 25 [ ] 15
Additions can be done in any order - putting the 15 first could be useful
3. What is 10 + 27 + 10?
 [ ] 45 [ ] 37 [x] 47 [ ] 54
Starting with 27 and counting up in tens is a good option to try
4. What is 23 + 45?
 [ ] 75 [x] 68 [ ] 65 [ ] 57
Partitioning means splitting up the tens and units, making this addition easier
5. What is 3 + 9 + 4?
 [x] 16 [ ] 15 [ ] 21 [ ] 19
Adding up in any order will give the same answer
6. What is the total of 7 and 26?
 [ ] 34 [ ] 43 [ ] 23 [x] 33
Starting with the larger number and counting on might be a good plan
7. What is 30 and 48 added together?
 [ ] 87 [x] 78 [ ] 76 [ ] 68
Adding the 30 and 40 first and then adding on the units is a good strategy here
8. What is the sum of 27 and 43?
 [x] 70 [ ] 80 [ ] 60 [ ] 56
Using the number bond of 7 and 3 might be useful
9. What is 8 + 9 + 7?
 [ ] 26 [ ] 25 [ ] 23 [x] 24
Trying to make 10 and then counting on, or using a near double of 7 + 7 could have helped
10. When adding numbers together...
 [ ] you should always put the largest number first [ ] you should always put the smallest number first [ ] you should guess the answer [x] you can add them in any order
Addition calculations can be done in any order, but subtractions cannot
