Outcomes
4.GS1.03
Identify benchmark angles (i.e., straight angle, right angle, half a right angle), using a reference tool (e.g., paper and fasteners, pattern blocks, straws), and compare other angles to these benchmarks
4.GS1.04
Relate the names of the benchmark angles to their measures in degrees (e.g., a right angle is 90ยบ)
