Great Activity

Topic: Angles

Grade: 5,6

Objective: The students will determine the number
of degrees for each angle of each pattern block by using the right angle
of the square as a reference.

Introduction: Have the students examine the pattern
blocks and discuss the definition of the various shapes. Stress that
the square has four right angles, 90 degrees.

Activity:

1. Have the students work individually with his or
her own set of pattern blocks.

2. Have the student make a chart to record their
data: the shape, the number of angles and the degree of the angles.

3. Have the student write a brief description of
how he/she determined the angle.

Closure: Have the students measure their angle to
check their accuracy and then record the measurement on their chart.

Assessment: The students would turn in their data
chart with their recorded data, measurements, and the description
of their strategy.
