Place Value

LI. To learn how to use the 'one for ten, ten for one' canon. This week for maths we learnt how to use the one to ten, ten to one canon to answer subtraction equations. I learnt how to answer subtraction equations by using the one for ten, ten for one strategy I also  learnt it by using the place value strategy. I learnt it because if there ever is a maths test while I'm in university to cover the whole year I'd be able to do it because I learnt it in school. If we are using the one for ten, ten for one canon the only answers are ten and one.
