Math - Geometry

Our next unit in Math will be Geometry. It is unit 3 in the Math Makes Sense 5 text book.

Using a Protractor

We use protractors to measure angles.

Here is a video tutorial from the Khan Academy on how to use a protractor:

Here is an interactive activity where you can get some practice using a protractor:

Don't forget there are also virtual protractors available at the Virtual Manipulatives websites that were mentioned in an earlier post:
