Task Description: This week we are learning to subtract numbers using different strategies. I learnt how to use many different ways to add and subtract math questions. I figured out how to use reversibility to turn a subtraction question into a addition question. This is one example of what i’m talking about: 21 – 7 = 14 so if you use reversibility and turn it into a addition question it would be 14 + 7 = 21. You can see I used the same numbers but turned the subtraction into addition and moved the numbers around for it to make sense. I found it a very useful strategy to use when I came across a question like this. I had loads of fun being able to work each question with some of my friends help. Hope you like my post check it out down below. Tyy <3
