This week in 2C we have been focussing on subtraction in Maths lessons. We have been practicing subtracting a one digit number from a 2 digit number. In order to secure this knowledge, we repeated our subtractions using lots of different methods and resources including 10 frames, number lines, 100 squares and counters. We also looked at related facts. One child said,
‘I know that 10 – 7 = 3, so I know that 20 – 17 = 3.
Help at home by practicing counting backwards from 10, 20 and 100!
