This All vs. Only Some lesson plan also includes:
All shapes have certain defining attributes that set them apart from others. In order to understand this, young mathematicians look at examples and non-examples of triangles, rectangles, and squares, working as a whole class to create definitions of each shape. To demonstrate their understanding of these new definitions, children are given a worksheet and asked to color a series of shapes according to their classification. This resource would serve perfectly as the introductory lesson to a primary grade geometry unit.
- Examples and non-examples of each shape clearly demonstrate their defining attributes
- Suggestions are included for modifying the lesson to meet the needs of all learners
- Teacher must prepare sentence frames to support children with the lesson's academic language
