I really like this graphing practice Desmos Activity created by @rnhung. The premiss is simple. You see a target "stuck" to a wall a distance away and have to throw a dart to hit the bullseye. You get three "throws" which basically means you have three chances to determine the coordinates of the bullseye. I like how there are no scales so there is definitely some guess work and estimation needed and the visual of the dart hitting the target is great.

I saw this in a presentation from @ddmeyer last year but thanks to @MathyCathy I was pleasantly reminded of it. If you're not sure what the deal is, then, as it was suggested in the comments, try to determine the area using more than one method.

Modified from a task shared by @ddmeyer, this is one of my favorite ways to end an introductory unit on linear relationships and slope. Today, ALL THREE CLASSES that tackled this task called my bluff with lovely math to support! #BigShapeIsNotATriangleYenca #iteachmath #MTBoS 💚 pic.twitter.com/6uHl7hHEwN— Cathy Yenca (@mathycathy) November 21, 2019
I love games that help kids practice their basic math skills. In this post, @mathforlove presents two simple dice games. 1) Roll three dice, add two then multiply by the other. The total is your points and 2) Roll three dice. Make a two digit number with the digits of two of them then divide by the other. The answer is your points (rounded down to the nearest whole number + with 10 bonus points if it divides evenly). See all the details at the link below.Curriculum Tags: Gr7, Gr8

This is a cool little clip showing a student misconception about measuring angles. I think it's important to anticipate these kinds of mistakes so that you can have something ready to say to them to help move them forward.
