The Big Idea: This week, we will begin learning about GEOMETRY and reviewing ANGLES. Here are the specifics:
- Describe quadrilaterals by their attributes
- Classify triangles as obtuse, right, or acute
- Distinguish between rays, line segments, lines, points, and angles
- Classify lines as perpendicular, parallel, and intersecting
- Find lines of symmetry in shapes and images
- Review measuring angles, joining and separating angles, and classifying angles as right, obtuse, or acute.
