Worksheet directions

Grade 6 • Guided Practice • Work with your teacher or a partner. Discuss the model or strategy, then complete each problem.

Sample questions

1. A trapezoid has parallel bases 9 cm and 5 cm and height 4 cm. Draw a second congruent copy to form a parallelogram. Use it to explain the trapezoid’s area.
2. A student uses only the longer base 10 cm and height 5 cm to get area 50 cm² for a trapezoid whose shorter base is 6 cm. Explain why this overcounts and find the correct area.
3. All measurements are in centimeters. Split this trapezoid into a rectangle and triangles, then find its area. Show your component areas.
4. A student uses only the longer base 13 cm and height 5 cm to get area 65 cm² for a trapezoid whose shorter base is 6 cm. Explain why this overcounts and find the correct area.
5. A trapezoid has parallel bases 12 cm and 5 cm and height 4 cm. Draw a second congruent copy to form a parallelogram. Use it to explain the trapezoid’s area.
