Great Maths in Year 1 – Using what we know

By 02/06/2018Maths, Year 1

Great maths from Year 1.  They are all using number facts that they know to solve other problems.

If you know 4 + 3 = 7 then you also know 40 + 30 = 70

If you know 7 – 2 = 5.  What is 70 – 20?

Why not tell Mrs. Whyman and explain to her how you know.

What other problems could you solve like this?
