last week we have been doing counting up, it is basically a number line (the e.g. is on the maths board).
1.make sure the largest number is first.
2.draw a number.
3.place the two numbers at the sides.
4.use number bonds to get to the next ten e.g. 28-30(2+).
5.Do a big jump e.g. 30-60(30+).
6.Add extra units e.g. 60-73(17+).
7.Add your jumps together 2+30+17=49
