Geometric Glossary
Fourth graders use drawing and paint tools to identify, draw and state several geometric terms.
Curated OER
Similar or Not?
Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.
