## Reflection: Intervention and Extension Floor Plan Areas (Day 1 of 2) - Section 2: Warm Up

If your students have a hard time getting started you might want to start with a simpler task. An easier entry uses the Black Pearl floorplan and asks for the combined area of the bedroom and closet. This problem has the two rooms separated already and provides all the necessary measurements. Because it is the handout for the next part of the lesson, students will not feel like they are behind. Once students successfully work it through you might highlight some of the unknown measurements and ask how they might figure them out and ask how the living and dining rooms might be separated into two separate rooms. This provides some scaffolding for the required reasoning.

One thing that may be difficult with the floor-plans is all the distracting information. Folding or covering part of the diagram can help students zero in on just the information they need for a certain part of the lesson.  Scaffolding their thinking without giving it away helps students persevere and make use of the structure in the shapes.
