Symmetry isn’t really all that difficult of a concept, that is, until my kids get to a test and mix it up with the word “congruent.” For
the last few years, I have been doing this lesson with my kids during Valentine’s Day week and they have a ton of fun.
First, you’ll need some bottles of paint. Usually I buy the big bottles of red, a few different pinks, white, and some of my kids like to add a little black to their hearts, too. The colors don’t really matter, but it makes things a bit more fun.
- Using construction paper, have the students fold it in half and cut the heart out.
- Once students open the heart, have them splatter some paint on only one side. I always have the students put their heart on a paper towel.
- Close up the heart and place another paper towel on the heart, squishing the paint towards the edges of the heart. Once fully squished, open up the heart. 99.999% of the time, you have a great looking symmetrical heart.
Let the paint dry and you have some great works of art. My kids always have a blast and never forget what symmetry is EVER AGAIN (at least for the rest of the school year)!
Happy Valentine’s Day!
