# Wednesday 13th May – Year 2 Maths Intervention Group

Today in maths, we are going to work out the related subtraction fact for an addition fact and vice versa.   Work through the first two slides to show you what to do, before attempting the third slide. If needed do the calculations with resources or jottings to aid your understanding.

When you add two numbers and get an answer. if you take away one number from the answer you will go back to the beginning.
