We had lots of fun learning about symmetry this week! Besides the lesson in our math book, we did all sorts of great activities to practice creating symmetry. We have our standardized tests next week, so we enjoyed doing some fun activities to unwind and relax before our long week.
First, we did a symmetry gallery walk activity. Each group got rulers and either pattern blocks or base ten blocks. They had to create half of a design on one side of the ruler. Then they had to collect the pieces someone would need to make the other half be symmetrical. This step is VERY important. Students that didn’t pay attention to that step created problems for the students that later tried to do the second half. After the students were done, they had a chance to walk around and choose another design to finish. Once they finished the design, they got to mix up the pieces and create a new design for someone else to finish. They loved creating designs and walking around to see everyone else’s designs!
Our next activity was probably my favorite! I took pictures of each student in front of the whiteboard. Then I went into PowerPoint and cropped each picture so it was cut in half – right down the middle of the nose. I printed them out (I used color, but you could also do it black and white) and surprised each student with their “half of a face”. I used an example to show them how they could use a ruler to measure to best match the other side of their face. Some however chose to just “eyeball” it. Then they mounted their picture on construction paper to post in the hallway! Some turned out amazing, others struggled, but they will make great memories for their family!
Lastly, I wanted to do something for Valentine’s Day that incorporated symmetry into a Valentine’s gift they could give to family members. I found this great post on Pinterest – Create Art with Me: Valentine’s Day Projects. I decided to use the bookmark idea to create Valentine’s Day bookmarks using symmetry.
Go to the blog post for all of the directions. I let my students create any design they wanted. Some obviously turned out better than others, as with any craft, but overall it was definitely a success. Instead of using packing tape, I just laminated them. If you don’t have a personal laminator for your classroom, I highly recommend it! So what symmetry activities are you doing in your classroom?
