Week of November 17-21

This week, 5a continued to work on their probability games.  By next week, they should be ready to be played and evaluated by our G&T classmates so that we can make final adjustments before inviting our classes in to play our games.

HW: p. 59

*Due to the lockdown, 5b did not meet this week.  We will continue to work on our games next week.

Classes 4a and 4b worked to finalize our mall ads.  Next week, we will shop in one another's stores and find the values of the variables in the ads.

HW: study for unit test by reviewing mathematician's journal (including glossary)

*Class 4c did not meet this week because Mrs. Emmich chaperoned the 2nd grade field trip.  We will finalize our mall ads next week.


Classes 3a and 3b explored boxes by looking at their faces, edges, and vertices.  We also found the perimeter and area of each face and used our measurements to calculate the total surface area.

HW: finish box poster and complete p. 75 in mathematician's journal



Classes 3c learned about surface area today.  We figured out that you must find the area of each surface of a rectangular solid and then add those areas together to find the total surface area of the figure in square units.  We talked about how much frosting it would take to cover the 4 sides and the top of a whole cake compared to individual pieces of the cake once it is cut up.  We realized that it would take a lot more frosting to cover each individual piece's 5 sides.  After all, when the pieces are part of the whole cake, the pieces have only one, two, or three sides frosted.  The video below give an explanation of how to find surface area if anyone needs clarification:

Use the picture below to help you with this week's homework.  You need to explain how to calculate the surface area of each individual piece of cake.
