This document describes a project-based math curriculum that uses real-world engineering projects to teach math concepts. It provides examples of several multi-lesson project units, including building a wheelchair ramp to teach proportions and a funicular system to teach the Pythagorean theorem. Each unit lists the math concepts covered and gives brief examples of lesson activities. Practical considerations are discussed, such as materials needed and costs. Finally, supplemental drop-in algebra units are described that can be used to reinforce major Algebra I standards through engineering design challenges.

Interested in offering project-based math in their academy – should have math cohorted, or have afterschool/summer options.
Raise hands for:What type of academy?What type of teachers/admin/etc?
Math concepts and skills students struggle with:Number sense and fundamental arithmetic (fractions, percent, decimals, estimation of reasonable answers)Basic problem solving skillsUsing geometry tools: ruler, protractor, compassBasic math vocabularyProportional reasoning, Slope, and ScaleConcept of AreaSolving simple equationsUsing formulas correctly in context
Projects create a need to know and motivation to learn math. They add relevance, authentic problem solving, and 21st century skills to math content.Hands-on, contextualized activities show students that math can be enjoyable, useful, and important. This increases achievement and retention.
Access Ramp activity. Find a partner. You need a ruler, pencil, and the handouts.Complete the assignment with your partner. As you work, list the math concepts you needed to be successful.
Each of these skills have scaffolding activities in the curriculum. They are all contextualized within the building and design theme. Problem solving is built in throughout the program.
