GRADE 8 MATHEMATICS

We are now starting Chapter 5 Surface Area. We will spend 3 weeks on this chapter. It has 4 sections. One week for sections 5.1 and 5.2, the second week for 5.3 and the third week for 5.4.

Section 5.1 View of 3D objects - page 164

Students will read and put in their notes the purple note on page 164 - How to describe a 3D object and read carefully Examples 1,2 and 3 on pages 165-167, as well as Key Ideas on page 168. This section as well as the next are meant to familiarize students with 3D objects before they get to actually think about surface areas.

I only suggest a few questions for practice : # 3,4,6,9 and 10 on p. 168/169

Section 5.2 Nets of 3D Objects - page 170

Students should write and learn the definitions of 'rectangular prism' and ' net' on p. 170, read carefully Examples 1 and 2 on p. 171-172 as well as Key Ideas p 173.

Once again I only suggest a few practice questions, # 3,4,6,7 and 8 on p. 173/174.

Next Monday we will get into the actual Surface Area of Prisms.
