Geo Jammin' - Day 2, Lesson 5: Eeny, Meeny, Miney, Mo
Students, in groups, use song lyrics and math to descrie two and three dimensional shapes.
Curated OER
Geo Jammin' - Day 3, Lesson 9: Attribute Attitude
Second graders read poetry and build their vocabulary through use of the puppet Geo George.
Curated OER
Geo Jammin' - Day 4, Lesson 13: Where, Oh Where, Can the Geo Be?
Learners listen to a story "My Crazy Dream" with an intent to identify shapes in ordinary objects. They raise their hands when they've heard an object whose shape they can identify. They discuss their findings.
