Building Familiarity with Degrees and Angles (Background knowledge)

Desmos Laser Challenge Kids adjust the angles of the mirrors and lasers to hit the targets.

Estimating Angles  Kids practice estimating the sizes of different angles. I’ve found they enjoy playing around with this for about 10 minutes.

Leveled Practice: Wagon Wheels Kids practice finding angle measures around a point. Builds numerical fluency working with the number 360.

Building Proficiency with the Coordinate Plane (Background knowledge) 

Desmos Battle Boat Kids partner up, swap laptops, and build proficiency by playing battleship.	Desmos Polygraph Points Kids play a polygraph game (think Guess Who but with math images) designed to elicit vocabulary related to ]the coordinate plane.	Leveled Practice: Plotting and Naming Coordinates Simple, straight forward practice. Source for projecting examples: https://www.bossmaths.com/g7a/	Desmos Pumpkin Carving Students carve a virtual pumpkin by plotting points. (~15 min)
Open Middle Problems #1: Graphing Points on a Coordinate Plane(source)	Write a letter: How to Plot Points Kids synthesize their learning by writing a note to a friend summarizing the steps for plotting points and creating an example.	Desmos Target Practice Kids practice graphing points by trying to hit targets.	Quadrilaterals and Coordinates Kids reason about distance on the coordinate plane and characteristics of special quadrilaterals to figure out coordinates of vertices. (No grid or labels, so kids really need to think about the structure of the plane!)

Describing, Visualizing, and Applying Rigid Transformations

(8.G.A.1, 8.G.A.2, 8.G.A.3)

Transforming Rabbits Kids describe the rigid transformation that takes Rabbit A to Rabbit B. Tracing paper necessary. Turn into a game!	How to get there? Kids figure out how to get from one triangle to another by applying rigid transformations.	Identify the Transformation Quick basic practice identifying types of transformations.	Congruent Halves These puzzles develop kids’ visualization skills, reinforce the idea of congruence, and rotations.
Desmos Rigid Transformation Golf Kids have to figure out how to use a sequence of transformations to move the pre-image to the image without hitting the obstacles. (Usually fun!)	Notes on Rigid Transformations Kids complete a graphic organizer with examples, definitions, and tips of all three types of transformations. (You could also have kids do this idea without the graphic organizer.)	Aaron’s Designs Kids practice drawing reflections and rotations, and describing translations on the coordinate plane.	Mini Transformation Art Project Kids rotate, reflect, and translate a picture in the coordinate plane. More examples to share with kids here.
