2D and 3D Geometry

This week in 7th grade math we have started our geometry unit.  We started the unit off by figuring out where the formulas for area and perimeter of squares, rectangles, parallelograms, triangles, trapezoids, and circles come from.  We cut these shapes out of grid paper and put them together to make other shapes to learn where the formulas come from.  For the rest of the week, we will be working on volume of prisms, cylinders, pyramids, and cones.  This is leading up to the water bottle project, which was introduced today.  Each student will be asked to create a water bottle out of paper using the shapes that we learned about this week.  The final project will be due in about a month.

Below is a clip from the Fibonacci presentation that we did last week.  All the kids did great work and learned a lot.  Other videos are posted on the NPES facebook page.
