Reflection: Pacing Area of Regions Formed by Inscribed Shapes - Section 2: Problem Solving


When I first made this lesson, I thought it was a cool idea to have students plot the shapes using ordered pairs.  It worked out well for the students who have no problems plotting ordered pairs.  They were able to create the shape within a shape quickly and accurately.  

Some students had difficulty with this.  While one might say this serves as good practice for graphing ordered pairs, I think that for these students it made the point of the lesson even less accessible.  These students would benefit from having the points plotted at the least.  Other students would benefit from having fully realized shapes.


  Should I have just given fully realized shapes?

Area of Regions Formed by Inscribed Shapes

Unit 6: Geometry
Lesson 5 of 37

Objective: SWBAT find the area of regions formed by inscribed shapes by problem solving

Big Idea: Students solve all the problems by first graphing the shapes on a coordinate grid.
