In our 2D Geometry unit, we’ve recently been identifying 4 types of angles:

• acute (less than 90 degrees)
• obtuse (more than 90 degrees)
• right (equal to 90 degrees)
• straight (exactly 180 degrees)

We decided to go on a scavenger hunt around our classroom to find examples of each type of angle. Students then worked together to made a pic collage to show their findings. We had a lot of fun! Have a peek.

What kind of angles can you find around your house?
