Word problems and strategies

I learnt how to use different strategies to solve equations using all four operations (addition, subtraction, multiplication and divison). A strategie is a plan to complete a task.

Some of our equations:

Our first equation was 84-7. We used four different strategies to solve this equation. One of our strategies was the number line. We started off at 77 and then added 3 to get to a tidy number which was 80. Then added 4 to get to 84.

Our next equation was 1.5-0.885. We used 3 different strategies to solve this question. One of our strategies was place value. We first started at 0.885 and then added 0.005 to make 0.900. Then added 0.010 to get to 1.0. After that I added 0.5 which made 1.5.

Our third equation was 88÷8. To solve this question we used 3 different strategies. Multiplucation was one of the stratergies. We times 8 by 10 wich makes 80. Then added 8 by multiplying 1 by 8.

I enjoyed this activity because I learnt some new strategies to solve different equations.

  1. Hello Te Raumati,

    These are some awesome strategies you have used and shown. What other strategies do you think you could use, and how would you show it?

    1. Hi Bella,

      Interesting question you asked. One strategy I can think of is counting on and I would use it for an easy addition equation. What strategies you know that can solve a multiplication equation?

    2. Hello Te Raumati,

      That's an awesome reply. I know that repeated addition and place value can solve multiplication problems e.g. 13x65: 65x10=650, 65x3=195. 195+650=845. What was the problem you struggled with, and why do you think you struggled with that equation?
