Back to School. Mental Math. Random Subtraction Sum Generator
This ingenious Powerpoint provides a subtraction sum generator for younger children. Simply click on the highlighted button and a random sum will appear. Give your students time to answer the question before clicking on the sum to reveal the answer. One more click on the answer returns you to the sum generator page. All sums use numbers from 1 to 9, making it suitable for younger children.

Ideal for whole class mental math sessions.

You can even edit the resource to input your own choice of sums. I am happy to answer any questions on this resource and explain how to edit it if you wish to do so. Please feel free to contact me through the TES site or by email at
