CMath Vo abulary solid figure: a figure that has 3 dimensions: length, width, and height
flat surface: a surface that slides
curved surface: a surface that rolls
2 Write the name of each solid figure. c 2. Have students match the solid figures to
real-life objects
ab
Explain the number of flat and curved
cube rectangular prism cone surfaces the solid figures have.
d e f Cubes, pyramids, and rectangular prisms
have flat surfaces.
cylinder sphere pyramid Spheres, cones, and cylinders have
curved surfaces.
Solids with a flat surface slide.
Solids with a curved surface roll. 3. Check Point
Some solids slide and roll.
The table shows the solids that can slide, roll, or slide and roll. Summarize the lesson by asking questions
about flat and curved surfaces.
Example: Which figures have both flat and
curved surfaces? Cones and cylinders.
