In Owls class this week, we have been working hard to master subtracting two 2 digit numbers. We found it tricky when we had to exchange one 10 for ten 1s. We started the week using base 10 to help us solve our number sentences practically and by the end of the week we were drawing the number pictorially and get quicker and quicker with our calculations.
Well done for persevering with a tricky concept!
