Week 2 maths teacher lesson

We used add and subtract to solve our answer. We break down the numbers
 to make the wholes then the left over numbers. For example 2 .80 + 3. 97=
2+3= 5,  first you make the whole for the tens. So 80 + something equal 1
whole.So you take out the 20 to make 1 whole and the leaf over is 70. Then
you add the 77 and altogether you add 5 wholes + 1 wholes + 77= The answer
 is 6.77 .
