Cram

Cram is a visual game played on a grid of squares. 4×4 or 6×6 are common, but encourage your students to try other (even irregular) board sizes. Two players compete, placing 2×1 rectangles onto the grid. The last player to successfully place a piece wins.
Here is a sample Cram game played on a 4×4 grid. Eventually, red cannot make a move.

Sprouts

Sprouts is a dot and line game played with just paper and pencil. Students draw a small set of dots to begin (even two dots is enough). The object is to continue connecting those dots with lines.
  1. Connect two dots with a line (curvy is fine).
  2. Put a new dot somewhere on that line.
  3. Repeat.
  4. Each dot can only have three lines connected to it.
  5. Lines may never cross each other.
  6. You lose when you can’t draw another line.
Sproutimation
In this sample, there is only one dot remaining in the end with fewer than three connections, so the player cannot make a new line.

Starting a New Unit- Stretching and Shrinking

Common Core Standards for this Unit:
  • 7.RP.A.2 Recognize and represent proportional relationships between quantities.
  • 7.RP.A.2b Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
  • 7.RP.A.3 Use proportional relationships to solve multistep ratio and percent problems.
Goals for this Unit:
  • Similar Figures Understand what it means for figures to be similar.
- Identify similar figures by comparing corresponding sides and angles
- Use scale factors and ratios to describe relationships among the side lengths, perimeters, and areas of similar figures          
- Use algebraic rules to produce similar figures
- Recognize when a rule shrinks or enlarges a figure
  • Reasoning With Similar Figures Develop strategies for using similar figures to solve problems
- Predict the ways that stretching or shrinking a figure will affect side lengths, angle measures, perimeters, and areas
- Use scale factors or ratios to find missing side lengths in a pair of similar figures
- Use similarity to solve real-world problems
