Lesson

NOTE: While we create most lessons on the Growing Math site ourselves, we do include links to other lessons that are exemplary in their cross-curricular, standards-based design. This is one of two lessons we love from Discover Dairy. The entire 14-page lesson can be downloaded here, including reading passages, lab assignments and answer keys.

You can also go to the Discover Dairy site, which requires a free registration and login to download individual parts of the lesson and see the other lessons they have available.

Start with a video

ASSESSMENT

Two types of assessment occur in this lesson. During the class discussion, teachers can get an assessment of the understanding of the concepts of the class as a whole and the lab assignment can be used for individual assessment.
