Welcome to my math blog! The purpose of this blog is to help you stay informed about our learning and experiences that have taken place during our math class. I have also included links your child (and you) may want to use in order to supplement math learning in 5th grade.

### Angles

Yesterday, my classes worked with the universal symbols that are used in geometry.  During that activity, they proved their understanding on acute, obtuse, and right angles.  Therefore, I decided to use our time today applying our knowledge of angles, instead of taking notes that are unnecessary.

I gave the students an activity from the AIMS Education Foundation called "Flight Paths."  Basically, students use a ruler to connect three cities and form an angle.  Once the angle was formed, I demonstrated using an index card to determine whether the angle was acute, obtuse, or a right angle.  You can watch this demonstration on my video:  Angles.

I did not ask the students to find the exact measurement of each angle, this is not a 5th grade TEK.  Instead, I asked them to label the angle <90 degrees, >90 degrees, or 90 degrees.

The kids really enjoyed this activity!  There was not a moment off task!  The most challenging part of the activity was finding the cities on the map.  I like when they can see how math intermingles with other content areas!
