Estimating Areas
Estimating Areas is a key Grade 7 math skill in Saxon Math, Course 2. To estimate the area of an irregular shape, overlay it on a grid. Count the number of full squares and then combine partial squares to approximate the total area. What’s next This Think of estimating area as a clever way to measure a messy, irregular shape, like a lake on a map or even a handprint.
