QuestioningWhat question(s) could you ask yourself to helpyou understand if two shapes are similar? Are the shapes the same? If so, they are similar
Thinking Strategies:Can you visualize and summarize what it means for two shapes to be similar? Basically, similar means “same shape, but could be different sizes”
ReflectionLook at your list of congruent items. What shapes are the congruent items? Why are they the same size? What would you have to do to two similar shaped items to make them congruent.
Making ConnectionsDo you see any congruent shapes in our classroom?
Did You Know?Congruent:Why such a funny word thatbasically means "equal"?Probably because they wouldonly be "equal" if laid on top ofeach other. Anyway it comesfrom Latin congruere, "to agree".So the shapes "agree"
Investigating Congruent Shapes In this investigation: 2. Each student will receive a card with a two-dimensional shape on it. 3. Your task is to find a student who has a card with a two-dimensional shape that is congruent to the shape on your card. 4. Be ready to explain why you think your shapes are congruent and (if not) why they aren’t congruent. cardWe will do this 3 times.
ReflectionIdentify a thinking strategy(visualizing, inferring,summarizing, connections,schema, questioning,…) thathelps you understand whatmakes two shapes congruentand explain how this strategyhelps you understand.
