Describe Shapes
- Grade:
- 1
- Subject:
- Math
This geometry lesson covers identifying two-dimensional shapes by their attributes. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will describe the attributes of a shape that are always true and sometimes true, and then match various shapes to the correct bin. Shapes identified are triangles, rectangles, squares, circles, pentagons, and hexagons.
Use a Property of Triangles to Solve for Unknown Angles
- Grade:
- 4
- Subject:
- Math
This measurement and geometry lesson focuses on using a property of triangles to solve for unknown angles. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students list the given angle measurements, then solve for the unknown angle by adding the given angle measurements and subtracting the sum from 180 degrees. Finally, they interpret the measurement of the angle. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
