Year 3 mental arithmetic: Sets 13 and 14

Two more sets of mental arithmetic questions suitable for Year 3 children. There are plenty of word problems this week which some children find much harder than just being given a sum to work out.

Perhaps one of the hardest types of question is the’ finding the number half way between’. Another tricky type of question is the ‘I think of a number and subtract’ type. This is difficult because finding the answer does not necessarily involve carrying out the operation spoken in the question. For example, I think of a number and subtract 12. The answer is 20. The answer can be found by adding (not subtracting) 20 and 12. Watch for the common error of answering 8 for this question.
