Ading Using Tidy Numbers

Today, we have learn to solve addition problems by first adding a tidy number and then subtract a small number to compensate. Room 12 have been doing this worksheet for this whole week. Here is a example for worksheet.

      +1
43+29=72
43+30=73
73-1=72
The answer for that problem is 72. We learnt these strategies so we can work it out in real life.
