Valentines Day at our house is all about construction paper. Making hearts and cards and decorations take over free time. That excitement extends well beyond when the candy is all eaten. I’m all about short cuts and time savers after the holiday, so I show the kids that if they fold their papers in half then they only have to cut out half of the heart to get a full heart. Of course they ask why - the question that rules every house with preschoolers. So I explain and we veer off into an adventure about symmetry. A heart is a symmetric shape. That means that one side is the exact same as the other side. Said another way, if you fold it in half on top of itself, the sides will match up. In the case of a heart, it is vertically symmetric. I refrain at this point to show them that it is not symmetric about a horizontal axis and I’m glad I did (we’ll get there in a second…) “Is anything else symmetric” they both want to know.
