Construction Site Math: Ratios

In this real-world application of ratios, students will learn what a ratio is, including ratios with three terms. They will see different ways of writing ratios, including fractions in simplest form. 

a:b     ab     a to b

Two short videos introduce the concept of ratios and each video includes real-world examples of ratios. Then several formative assessments are used to test for understanding.  

Students then look at the application of ratios to the mixing of concrete at a construction site, starting with a video then followed by an assessment.

This lesson can be assigned to individual students or teams of students. The lesson can be completed in about 20 minutes.
