My students are learning about triangles, their characteristics, using a protractor to measure the angles, and how to find missing angle measurements when two are known. So, combining ALL of that, we made these pretty pine tree scenes inspired by this blog post from this lovely blogger.

They then set that out to dry and using watercolors and crayons, created a nice snowy outdoors scene that will eventually house between 3-6 trees (I let them decide how many to make.)
The next day, the students cut out their trees. I encouraged them to cut out triangles of all sizes. They then went to work measuring the angles and describing them. I asked them to not only measure each angle and record it on the sheet, but also to write down if it was acute-scalene, or any other combination (which meant that they needed to use the ruler on the protractor to measure the sides of the triangle) Click here to get the recording sheet we used.

|Here is one final product. You can see the scene drawn at the top as a sort of diagram to identify which tree belongs with which measurement.|
|Here is another one that is *almost* complete. Just need to color the diagram.|

Now, all of this will become a little bulletin board until right before we go on break. Then, I am planning on taking it down and the scene will become the cover of the holiday card the students take home to their parents. Win-win.
What fun, standards based projects do you have in store for the next few weeks?
