my maths

I have been  working hard on my maths and this is what I have been doing

WALT: make a tidy ten

• I learned to make  a tidy ten by using what I know
• Most challenging was using what I know
• Next step is to use what I know and not do 21 + 8 + 2 = because I can do 21 + 9 + 1 = so I can use what I know

I am in the yellow group the circus and I have been working on number lines and doing these it is things: 21+34+18= 73

_+1_+8_+ 30_+10_+3_
21 22   30     60   70   73
