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.
