Both grades should have their four graphs of (time, heartbeat) and a copy of their story put in the tray.
7th grade: We reviewed page 42 A&B in class today and worked on page 43 C. The relationship between scale factor, proportional side lenghts, perimeter and area are being explored. Exponential realationships are implicit and a desired place for the class to go.
8th grade: We are modeling a bridge and looking at the variables of thickness and length. We found the thickness is linear and the length is not. Graphs, tables and questions on page 7 & 9 should be completed and lend support for the conclusions.
