Microteaching BOOPPPS Lesson Plan - Transformations

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); familiarize ourselves with the TI-Nspire.
Teaching Objectives: TWBAT have a group work together to ensure that all concepts are understood; familiarize ourselves with the TI-Nspire if we can get them.
Pre-test: Sara’s group activity. Show some pictures of graphs, ask about what kinds of transformations; play with TI-Nspire, what happens if a>1; 0< a <1
Participatory Activity:
Materials: TI-Nspire, back-up: 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?
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.
