This lesson is great for reviewing the concept of area. The definition and formula are covered, and students have the opportunity to solve 24 problems involving area. Some of the problems are adding the area of 2 buildings, some are comparing the area and finding the difference, and the others are finding the area of odd shaped buildings for which the formula doesn't work nicely.
This is NOT a packet of worksheets! The format is a Power Point Presentation, that has animations built in to help guide the class through a study/review of the concept of area and the application of the formula in problem solving for computing area. There is room built in for lots of classroom conversation and interaction.
All of the activities in this presentation are also included in my Area & Perimeter Task Cards.
