*Math 8* – **Who Gets There Faster, Jim or Stan?**

Today I worked on giving most of the instructions/prompts verbally. I thought it would be prudent to write down the numbers required though. Maybe I should have tried it without the writing.

And a nice solution below…

While several groups clued in that distance/speed is time, lots of groups used equivalent ratios for their solution, which I was fine with. The reasoning would be something like “Jim goes 9km in 2hrs, 13.5 km in 3hrs, and over 11km in 2.5 hours…”

The next problem was simply stated: **I have a rectangular prism with side lengths 8, 9 and 12. What is the furthest distance from one point to another?** One solution is shown below. Once students were able to picture the vector they needed, many were able to find the correct answer. I liked this problem because it had a low floor – all groups were able to find some diagonals using the Pythagorean Theorem.

I was very proud of this lesson, both for what I had planned and on what students were doing. Virtually all the students were engaged and accountable. Even border kids who typically sit back a bit were interested in working on possible solutions.
