By the end of year 3 children are expected to be able to subtract a single digit from any 2-digit number. Knowing the patterns involved can make this much easier and this worksheet looks at these patterns.
The number sentence has three missing digits and children are asked to write a digit in each box so that the calculation is correct. There is a limited number of possible correct answers and the second part of the page looks at finding all of them. This is a fairly straightforward page as there is no adjusting or decomposition involved. Look for a logical, well ordered way of working for the second part of the question so that all possible answers are found.
