The goals of the class:
1. Correctly stretch and shrink figures on a coordinate graph using rules.
2. Identify similar figures and imposters.
The students were exposed to the character Mug Wump in Investigation 2.1 in their text. Students were introduced to the vocabulary: rule, proportion, scale factor, similar, and imposter.
We graphed the first mug wump coordinates together then I showed how to apply the rule to the other wumps. Students then worked on their own creating data points and graphing the characters.
The students final task was to complete the plotting and find out which wumps are imposters and which are similar to the original, Mug Wump.
