Square Game
We will look at a pair of ‘games’ involving squares in a rectangle and investigate some questions and create some puzzles connected to the games.

Also, Arizona Association of Teachers of Mathematics

Grid Fun
In this session we will explore a number of mathematical explorations on grid paper. Dave will take requests for activities suitable for various age ranges.

Grid Session Notes

Here are some Cartiasian coded pictures:

There are various ways to play “battleship” to reinforce the relation between coordinates and points.
Here is one description:
Geogebra Battleship

Another activity I did not get to was making one figure and then scaling it up my labeling points and then multiplying the coordinates of each point by a number (say 10). You can use this to transfer
a picture a student draws on graph paper to a much larger version for a classroom wall.

There are so many things that can be done here…
Explore areas of tilted squares… Get Pythagorean theorem.

Perimiter vs area for edge-connected, simply-connected (or not) grid regions.
