Visuals for Surface Area Homework
In Tlaloc's book, we looked at the same question that I used the interactive software (from Tuesday's post), but broke down the box into the faces and then calculated the areas.
It seems that this might be the first time you are encountering this concept. It can feel very overwhelming, but take it one "face" at a time and draw pictures, if you would like.

I selected question # 8 because it resembles an EQAO type question. It is layered and, I have to admit, the type of open-ended thinking that a part of the assessment looks at.
Tomorrow, someone can fill in the calculations, but I thought this visual might help some of you, who are stuck on the question. |
Formula offered by Isabelle, in Grade 7:
This video was looking at a couple of the cardboard models I used to introduce the topic.
Over the coming days, before the Math component of EQAO begins, we will be looking at some more of the topics we have not covered so far this year. Speaking of EQAO, here are the dates:
Make up dates will be on Friday, May 26th and May 29th |
