Shapes Are Fun!

This week’s math lesson focused on the tops of Geometry and Symmetry. To begin class, we began an activity where each group was given Halloween shapes and we were asked to find and discuss the similarities between each of our shapes. We came the conclusion that each table was given the same shape but each shape had different properties. This task was important because it helped us define what the term “similar” meant in relation to mathematics and geometry. Following this exercise we discussed symmetry and what it means for something to be symmetrical. We used examples and manipulatives to help us understand that, in order for something to be symmetrical it must have sides or halves that are the same. For example, If you split a square in half than both sides are symmetrical because both sides are the same.

I am becoming very fond of the idea of introducing mathematical concepts to students through story telling.  I think that it gives students a fresh perspective on mathematical topics that are relative to their experiences through their young and adolescent lives.  If students can relate to something, then it makes it so much easier for them to understand concepts and ideas. Mathematics is largely about relationship and if we have experienced something throughout our lives then we usually have a deeper understanding of concepts and problem solving.  The book called “ The Greedy Triangle” by Marilyn Burns introduces children to shapes and polygons.  This book is excellent for early learners of math and can be connected to the mathematics curriculum for geography, within many grade levels. As a teacher I would use this as a resource to extend my students knowledge of simplistic shapes and then carry on to discuss shapes beyond those mentioned in the book. Overall, I thought that this book was an excellent resource that could be used for many grade levels. 

In class this week, Courtney had a great geometry activity. She began her activity by introducing the class to symmetry using drawings on the board and folding paper shapes as a physical manipulative. The point of the introductory activity was to help refresh our minds on finding lines of symmetry. Afterwards, she had a secondary activity, where students went on a treasure hunt for Halloween candy. Students had to determine whether or not, shapes were symmetrical or asymmetrical and then determine their lines of symmetry. Once they identified these properties they had to fill them in on the activity sheet. The first group that completed the activity sheet correctly received the pirate’s treasure. I though that this was an excellent activity to introduce students to symmetry and working with 2-D and 3-d shapes. I really liked the assortment of the learning activities that we had in our class this week. As a teacher candidate, I can envision myself using many of these activities that we have seen thus far in our class because they have been extremely creative and have provided students with the opportunity to engage in exciting mathematical activities, where any student can participate with confidence.
