Patterns for Algebraic Thinking

**Number Cruncher**-- Students can easily see patterns, using a two-column table and when they know the machine's rule, they can type it in and check their answer.

**Function Machine**-- Students must create their own tables to record inputs and output.

**Shape Pan Balance**-- uses a balance scale to compare the weights of different shapes.

**Patterns in Math: People Patterns**-- See if you can extend the row of smartly dressed people -- chose your level of play. Then have students share the reasoning process.
