Week of March 2nd

I have to apologize, it has been a while since I have posted to this Blog.  February has been a busy month. We have spent 2 days taking a benchmark over writing, I have spent 4 days with students from Mance Park in Washington DC, among other things.  You can check out my Blog on our DC trip here if you are interested in that trip.  7th graders at Mance Park will have an opportunity to sign up for next years trip in May.

This week we will be finishing up surface area of rectangular and triangular prisms, cylinders, pyramids, and cones.  Some of these shapes have a formula that you can use, but I would rather them understand that to find surface area you just find the area of each face on the figure and add them together.  Here are some examples.

Example:     Rectangular Prism

Example:     Triangular Prism

Example:     Cylinder

Example:     Pyramid

Example:     Cone

Examples from Google Images.

Our schedule for this week will be:

Monday - Finish lesson from Friday and complete an assignment on Surface Area.

Tuesday - Test 5-1 Review - Topics:  Volume and Surface Area of Rectangular and Triangular Prisms, Cylinders, Pyramids, and Cones.

Wednesday - Math Benchmark Test

Thursday - Reading Benchmark Test

Friday - Test 5-1

March 9th - 13th - Spring Break
