Lesson Plan Description
This half day lesson plan is broken down into 2 separate segments (45-90 minutes each) addressing Measurement and Data: Area (3.MD.C5 & 3.MD.C6). These lessons include: key area vocabulary, guided and independent practice of concepts, and a game to reinforce the concept of finding area in square units.
- Segment 1: students will name different situations when area is measured, define a square unit, use a square foot to measure an area, measure area by counting the unit squares, and label an area with “x” square units or units squared.
- Segment 2: students will create their name on grid paper and find the area for each letter and total area for their name.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
