There are two sets of ten questions on each of the four pages of these resources, which can be used as a quick assessment as to how well addition has been learnt. The questions cover addition of two single digit numbers. There are several stages to go through when learning these facts. Firstly, to use number lines or fingers to count on. Secondly, to realise it is usually better to start with the larger number. Thirdly, to begin to internalise some of the facts so that they are known. Fourthly, to know them all 'off by heart'. You will know when your child has reached this fourth stage when it only takes them 10 seconds to complete the 10 questions! Year 1 addition: Brainwhizz challenge
