Activities at Home
- Use grid paper to create congruent shapes.
- Identify, describe, and classify different household objects as solid figures.
- Identify angles that are less than, equal to and greater than right angles.
- Use tangrams to make plane figures.
- Cut pieces of yarn to make line segments. Measure each segment in inches (to the nearest quarter inch) and centimeters.
- Go stargazing and make imaginary line segments by connecting the stars (points). Create geometric shapes.
