Lesson 8 of 14
Objective: Students will be able to solve non-routine area problems.
In this individual assessment, students see a variety of area problems that target different kinds and levels of thinking.
- Problems #1-5 and #7 are foundational problems that require students to solve basic area problems
- Problems #6 and #8 require students to think more critically, applying different strategies (like proportional reasoning) to solve.
- Problem #9 requires students to critique someone else’s reasoning
- Problem #10 is a context application problem similar to the Grazing Goat problem students saw earlier in the unit (MP3, MP1).
- Problem #11 gives students the opportunity to discover something new—the fact that connecting the midpoints of any convex quadrilateral creates a quadrilateral whose area is half of the original figure’s area.
Homework: Previewing Volume
Similar to how this unit has gone so far, I want to make sure I have opportunities to formatively assess my students’ understanding. I give the volume notetaker as homework so students can preview volume ideas on their own and explain their thinking in their own words, which will give me a lens into their thinking and understanding.
