The Lake Problem: There are some adults and children who need to get across a lake, and only one small canoe. How are they going to get everyone across?
How many adults and children are there? Who can fit in the canoe? Are there piranhas in the lake? So many questions to ask! Students want to know!
Crossing the Lake is a very rich, non-routine problem. Its context, coupled with careful posing of the situation, motivates students to persevere and look for structure in solving it, and allows for multiple solution paths and modalities. In addition, it creates a purpose and a need for using algebra.
The Center for Mathematics and Teaching (CMAT) provides cognitively demanding and engaging materials that are accessible to all students. At CMAT, we believe all students have the ability and deserve the opportunity to learn the mathematics that will make them capable and confident problem solvers, and put them on the path to college and career readiness. Our mission is to ignite and nurture passion in students and teachers about the elegance and utility of mathematics.
