Children have learned in Kindergarten to identify, name, and describe a variety of plane shapes such as circles, squares, triangles, and rectangles as well as recognize solid shapes such as spheres, cubes, and pyramids. In this unit, mathematicians will extend that knowledge to compare shapes, and determine how they are alike and different, by describing their geometric attributes and properties. In learning about solid shapes, with the addition of rectangular prisms, cones, and cylinders, children are taught to recognize them from different perspectives and orientations.
Children will get to compose and decompose plane and solid shapes, and make patterns with plane and solid shapes. As they combine figures, they will develop a better understanding of part-whole relationships as well as the properties of the original and composite shapes. This will also build a background for learning about measurement and properties of geometry such as congruence and symmetry at higher grades.
The mathematical concepts in geometry can be related to objects in the real world, so children are encouraged to use basic shapes and spatial reasoning to model objects in their environment. As part of a Researcher’s Workshop connection, students will design a community park using geometric plane and solid shapes. They will work collaboratively on a team to create a blueprint of their park and a 3-dimentional model.
