WALT: Use appropriate strategies to solve problems.
We had to do a broken calculator task. There were only two numbers (4&5) and a minus and times symbol. I had to use lots of strategies like mixing times and minus equations. For example, to get 5 I went 5x4-5-5. Here are my answers and my strategies.
I know this calculator made you think "outside the box" a bit, Ana. But your basic fact knowledge of your "4s" and "5s" really helped you. Maybe now you could try a few more different broken calculators using different number groups.
