Perimeter, Area, and Volume: Tips and Tricks

  • On the board, draw various examples of parallel, perpendicular, and intersecting lines. Have students distinguish among them. Then have students label and name a point on a line, a line segment, a ray, and an angle.
  • To help students identify different types of polygons, prepare sets of index cards with a figure on one side and its name on the reverse side. Have students work in pairs and name each figure.
  • When discussing solid figures, have solid figure models available in the classroom for students to handle.
  • Using solid figure models, have students identify each face, tell whether it is a polygon, and identify the polygon.
  • Introduce the concept of area and volume by modeling. Have students use unit squares to find the area and unit cubes to find the volume. This will help students remember that area is measured in square units, and volume is measured in cubic units.
