A Review of Some of the Measurement Concepts We Have Learned

Over the last few weeks we have been learning a number of concepts surrounding measurement. We have learned how to find the area of parallelograms and triangles, the surface area of rectangular prisms and triangular prisms, and finally the volume of rectangular prisms and triangular prisms. Here are some videos and blendspace lessons that can help students to review and better understand the concepts.

Surface Area of Rectangular Prisms:

How to Find the Surface Area of a Triangular Prism

Today your task is to find the surface area of triangular prisms. Remember that surface area is simply the area of each face of a shape, all added together. This is really easy for a triangular prism. First watch this video which explains how to find the surface area of a triangular prism:




Now let's practice using these worksheets (skip the questions about cylinders though):

If you finish both of these, please hand them into the teacher, and then try the surface area problems here at Khan Academy. Careful - some of them are hard!

Calculating Surface Area of Rectangular Prisms

Today we took up the challenge of finding the surface area of a rectangular prism. After finding the surface area of the large crate in our learning commons last Friday, we tried it with new measurements. Here is the challenge from today's lesson:





Once students were able to find the surface area of the crate, we figured it out without the bottom. Finally, we did a question from EQAO to find surface area. Here is a video I made to help students understand how to find surface area as well. In the video, I show a formula for it. I found today that students understood the concept of finding surface area so well that they do not really need a formula to assist them. They understood that they had to find the area of each face and then add them together. They also understood that opposite faces were the same, so they didn't have to calculate all six faces, but rather just three of them, and then multiply by 2 for each. This is how the formula demonstrates it as well. Here is the video:

Area of Triangles and Parallelograms

Over the last couple of days, we have been learning about how to find the area of triangles and parallelograms. First, we reviewed about how to find the area of a rectangle using the formula:

Area = Base x Height

Once students understood this, then we cut a piece of paper from one corner to an opposite corner to find out that we get two identical triangles. From this, we learned that the area of a triangle is exactly half of a rectangle that has the same base and height. We derived the formula:

Area or triangle = Base x Height / 2

Finally, we positioned the two triangles to make a parallelogram! This told us that the area of a parallelogram and the area of a rectangle are the same, so we can use the same formula:

Area = Base x Height

One part that challenged many students today was using the formula to help find the missing side of a parallelogram or triangle when given the area. Here is a video I made to help students better understand how to solve these types of problems:


Here is a link to a Blendspace unit that covers many of the concepts for this unit:

Reminder About Pyjama Patrol Drive

In keeping with the school theme of Love for the month of February, the Kingdom club will be hosting a Pyjama Drive for the Pyjama Patrol, a local charity run by a parent in our community. The drive will be run from February 6th until February 17th, and end with a pyjama day for all students! Please consider donating a new pair of pyjamas for a child who may not have a pair. We will also happily accept donations of money, blankets or new toiletries to assist those in need during this month. Thank you so much for your assistance! See the link below for more details!
