Maths Quiz - Year 1 Numbers - Missing Numbers (Answers)
This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 5 and 6 in year 1. Specifically this quiz is aimed at the section dealing with working out missing numbers in number sentences.
Finding the missing number in a number sentence such as 7 = ? - 9 will require an understanding of the symbols used and what they mean, as well as an understanding of how subtraction and addition work and how they are related to each other. To find the missing number in the above sentence, for example, understanding that '=' means 'is the same as' should help to work out that 16 - 9 gives an answer of 7.
