Stirring Up Some Math!
 As teachers, our goal is to teach mathematical
concepts to our students in a way that they can apply it
beyond the doors of our schools.
 Although you may not see it, math is all around us in
the real-world: in stores, banks, on television and the
Internet, and even in our own homes.
 Instead of teaching the concepts in school first in
preparation to apply them later in life, let’s begin the
application now. Let’s apply the knowledge as we gain
it…starting in the kitchen!


Stirring Up Some Math!
 In this project-based lesson, students will apply mathematics
while cooking various recipes. There will be some problems that
they have to solve along the way, which will require critical
thinking skills.
 As the teacher, you choose how to assign the recipes. This lesson
can be completed in groups, partners or by individuals.
(Remember: students work best when their interests are
heightened and their minds are challenged!)
 All of the recipes are “no-bake,” but may require a microwave and
a refrigerator. If you don’t mind getting a little messy, you can opt
to make these recipes in the classroom, or assign them at home.
 IDEA ALERT: Why not incorporate this lesson into a Classroom
Bake Sale/Math Fair?! You can raise money for the classroom or
an organized charity and learn about math all at the same time!
