A Dreamer's Cloak
Learners listen to the teacher read "A Dreamer's Cloak." They examine the difference between squares and circles and create their own cloak by using a paper bag and different shapes.
Curated OER
Line and Shape Game
Learners play the "space-breaker" game, in which they are required to create a picture using shapes or lines called out to them) to reinforce the concept of geometric shape and line.
Curated OER
Polygon Mobiles
Students explore a variety of shapes and angles and create mobiles with information about a selected polygon. Both common and "not-so common" polygons are examined.
Curated OER
Visual Patterns in Tessellations
Students explore tessellations as well as various types of polygon. Students examine tessellating patterns in the world around them. Students examine tessellations by creating their own tessellations and completing the included worksheet.
