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 twodigit number and ones, a twodigit number and tens, two twodigit numbers and three onedigit numbers.
Calculating totals means looking at the numbers in an addition calculation and thinking about a sensible way to add them together. When three onedigit 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 twodigit 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 twodigit number and a onedigit number. Recognising that additions can be completed in any order could help with this.














Adding the 10 and 10 up first, then adding the 9 might have helped

Additions can be done in any order  putting the 15 first could be useful


Starting with 27 and counting up in tens is a good option to try

Partitioning means splitting up the tens and units, making this addition easier


Adding up in any order will give the same answer

Starting with the larger number and counting on might be a good plan


Adding the 30 and 40 first and then adding on the units is a good strategy here

Using the number bond of 7 and 3 might be useful


Trying to make 10 and then counting on, or using a near double of 7 + 7 could have helped

Addition calculations can be done in any order, but subtractions cannot
