Mrs. Prokop’s 2nd through 5th grade math students at St. Mary’s Catholic learned about 2D and 3D shapes. These students have used manipulatives and visual representations throughout the year to build conceptual understanding in mathematics.
Graphic Organizers for 2D and 3D Shapes
For example, 2nd grade students explored the attributes of both 2D and 3D shapes and recorded their findings on graphic organizers. They manipulated 2D (two-dimensional) figures in order to discover the number of
The students manipulated 3D (three-dimensional) figures to discover how many
- faces, and
- vertices each figure has.
After exploration with manipulatives, the 3rd, 4th, and 5th grade students created flip books to show fractions through twelfths that are equivalent to 1/2.
