This problem encouraged you to work as a group, discussing and sharing different calculation strategies. There may be several different ways of working out the answer to a particular calculation; some are more efficient than others. Can you find different ways of working out the answer to the questions? Look at different types of questions, such as the ones given in the problem. Are the same methods always the most efficient?
William and Conner from St Patrick's R.C. Primary School submitted their solution:
William and Conner tackled these problems by splitting the numbers into more familiar-and easier to handle- numbers. They then dealt with these separately and combined the answers.
Ben, Aeron, Isla and Emily School from St Mary Redcliffe Primary explained how they worked out their answers to the calculations on the cards:
The Maths Group at St Teresa's in Surrey had some slightly different methods:
Very well done. I wonder which method you prefer in each case? Or perhaps you have a method that you think works even better for you?
