Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands and Geoboards. Through this engaging activity, they will begin to understand and identify the simple fraction of one half as they place two triangles together to make one square. To further their understanding of the basic figures within two-dimensional shapes, learners create shapes using Wikki Stixs. To complete the lesson, the class creates three-dimensional figures such as a cube with marshmallows and toothpicks. Included are extension and family connection activities. Please note that modeling and support will be needed for your youngsters to independently create shapes using hands-on materials as indicated in the lesson.
