Does anyone have one of those new coloring books that are totally cool? Filled with awesome designs, these books encourage you to just sit and color. In fact, studies suggest that coloring helps relieve stress and improve relaxation. I would agree. I like to sit and color while sitting on the couch or watching tv. Which is why I came up with this lesson for my students!
We are working through our geometry unit right now in both my seventh and eighth grade classes. Lots of angles, triangles and other polygons going on! I wanted to do something a little different than just a regular worksheet and take a break from our normal routine of class. I was browsing Pinterest (what else is new) and saw a picture of a whole bunch of shapes in different colors; shapes that could be used as artwork on walls. Immediately,an idea popped into my head! Math + art = awesome!
My seventh graders had just learned to classify triangles by their angles and sides. I decided to take triangles, and have students make them into cool designs while still practicing their classifying skills!
Only a pencil, ruler, paper and colors were necessary for this activity.
Students drew lines across the page using their pencils and made several triangles. I warned students to not draw TOO many triangles because that might make way too much work for them later.
Next, students identified triangles on their page as scalene, isosceles or equilateral. They traced each type in a different color of their choosing, being sure to put their color choices on a key.
Finally, students shaded in each triangle according to the angles. Obtuse, acute and right triangles each received their own color. Colors used should also be recorded on the key.
The class loved the project. After I gave instructions, the class was quiet for several minutes, not because I told them to be, but because they were so focused on their triangles! Designs turned out really neat. I’m thinking a new bulletin board display is coming…!
