Congruent / Similar Shape Cards
Cut apart 16 cards with 8 congruent pairs of geometric shapes, then have your class match the cards which show congruent shapes. There are no directions or information on the page so use your imagination to create a fun activity. Tip:...
Curated OER
Similar Situations
Students explore intersecting lines. In this intersecting lines activity, students investigate shapes consisting of parallel, perpendicular, and similar lines. Students investigate these lines in shapes around them.
