**Materials Needed:** Pattern Blocks

### Procedures for Students to follow:

- Using the pattern blocks, decide if either one block has an obtuse, acute, or right angle.
- Place this information in table form and be sure to state which shape you are referring to.
- Next form a right angle, obtuse, and acute angle using toothpicks.
- Glue the toothpicks to construction paper and label each angle.

#### Assessment:

- Take a grade over table.
- Have students find at least 3 acute, obtuse, and right angles around the classroom.
- Take a grade on the toothpick exercise.

#### Miscellaneous teacher notes on assembling this activity:

The toothpick exercise does not have to be used.
