Bridge: Hopefully we can lead in from Sara’s group who discuss translations. Transformations are everywhere: small child -> stretched child, smiley face -> stretched to oval face, motorcycle to transformer
Learning Objectives: SWBAT graph y=af(x); y=1/f(x); y=-af(x); y=f(-ax)
Teaching Objectives: TWBAT have a group work together to ensure that all concepts are understood
Pre-test: Sara’s group activity. Show some pictures of graphs, ask about what kinds of transformations
Participatory Activity:
Materials: peg board, graph paper
1.) graph 1; given transformation instructions, what will the graph look like afterwards?
2.) graph 1b; given the transformation, what was the transformation instructions?
3.) graph 1 and 1b by using TI-Nsprie, let student see how their answers are.
Post-test:
have each group set up a graph using the peg boards, and a set of instructions; pass graph to R and instructions L. following those instructions, transform the given graph.
Summary: review of the transformation rules and translation rules.
