## Explain

Have students convene to share their findings. Some students may have reached different results depending on which way they measured (which directional orientation they started with). See if the students can figure out why their numbers are different.

Ensure that students understand that the sun is directly overhead in the middle of the day (this is the right angle).

Explain that the sun rises in the east and moves through the acute angles in the morning, passes the right angle around noon and moves through the obtuse angles in the afternoon and evening.

Ask students to write down an obtuse angle that they might see from the sun in the afternoon.
