First Day Geometry
Like most teachers, I struggle with what to do on the first day of class. This year in my Geometry classes, I started with ‘Me by the Numbers’. It worked well and the students seemed to like it, but even this activity only takes 15 minutes of my 90 minute class. I decided to try something new. I broke the students into groups of 2 or 3. I gave each group a net for a cube. I masked each group to design a cube. They had access to colored pencils, scissors, and tape. Some cubes were basic and others were quite ornate.
When all the groups were finished, I collected the cubes. I then redistributed the cubes to different groups. Each group now had a cube that they did not design. I handed out another blank net and asked them to copy the cube that was given to them. Some groups had a more difficult time than others depending on the complexity of the cube assigned to them. The students had a good time and it gave me a chance to walk around the room and get to know them. My goal with this activity was to get my students to realize that taking a 3 dimensional object and trying to reconstruct it using a 2 dimensional template is difficult. Some students really excel at this and others really struggle. I feel like Geometry is often the math for those students who aren’t as good at solving equations. I wanted to take the fear of math and the unknown away as we started Geometry.
