Walt: solve addition problems by first adding a tidy number and then subtracting a small number to compensate.
This is my worksheet. You have to work out the equation by using tidy numbers and a number line. I have learnt a lot. Developing these strategies helps me work on my adding, number lines and tidy numbers. I want to work on my numbers because I want to add numbers very quickly so I don't take forever to figure it out.
