Strategies of Solving

We learnt about the different strategies of solving equations.

First, we were answering questions based on addition and subtraction. My group knew that a number line could help with both, addition and subtraction, so we showed that. Written algorithm was also one strategy.

The first question, was 84 - 7. With the number line, we got the answer of 77. We check if this was correct by adding 3 to 77 because we knew that that was going to make 80. Then, we added four more because if you take three away from seven you get four left. This made 84, and we knew that 77 was the correct answer.

The next set of questions were based on division and multiplication. The first question was asking what 5x5 was. The strategies we used were: skip counting in 5's, repeated addition and written algorithm. 5x5 means that you need to skip 5, five times. We knew that 5x5 = 25, so we did that.

I enjoyed this activity, but found some of them difficult.
