Article excerpt

1. Fold two 3"x 5" index cards in the middle, and tape them to

make 4 walls of a box.

2. How many dimensions can you measure using sugar cubes?

[ILLUSTRATION OMITTED]

OBJECTIVE

To measure a box in1,2, and 3 dimensions. To calculate area and volume by multiplying lengths.

LAB NOTES

Introduction: Ask students to identify each dimension below as YOU act it out. Then call out dimensions for THEM to act out.

1-dimension = Width, Length, Height or Depth: Pantomime stretching out invisible string.

2-dimensions =Area: Pantomime wiping an invisible, flat surface.

3-dimensions = Volume: Move hands in all three directions to occupy 3-D space.

Step 1. Fold the cards evenly in half. Match and secure edges with tape. Prop open into a "box."

Step 3. All dimensions come out about even. Students can stack sugar cubes to find answers, or multiply the sides to find area and volume.

EVALUATION
