MPM1D1 - Day 4 Order of Operations & Pythagorean Theorem

We had an assembly today so it was a shortened period. I had thought that it might be a good day to try a visual pattern but decided against it.

Instead we started with our first Which One Doesn't Belong. I decided to use the one below only because my students have seen cards a lot this week. They see them every day to determine where they sit and they saw them when we played integer solitaire. I was curious to see if any of them would make a connection back to the game about black being positive and red being negative. It turns out nobody did.

In our discussion yesterday about multiplying and dividing integers, order of operations came up. They all seemed to know the rules so I went over them fairly quickly but we did spend a bit of time talking about exponents. I gave them a few questions to try and then we took them up.

We also went over the Pythagorean Theorem. They knew how to find the length of the hypotenuse from yesterday's work so we worked through an example of finding one of the legs. I gave them some order of operations and Pythagorean Theorem questions for homework.


  1. I am doing review of skills. Division by zero came up. Also looked at the question "What's the last digit of 7^43?" Lots of great discussion. First test is no calculator.
    Keep doing great things!

  2. Those are some great discusison topics. I love having those conversations.

    Thanks for the comment.
