What algebraic content is in the problems?

b. 

What content does it prepare students for later?

c. 

How does this content relate to the mathematical ideas in this course?

d. 

How would your students approach this problem?

e. 

What are other questions that might extend students' thinking about the problem?

f. 

Does your current program in mathematics at your school include problems of this type?

Problem C5

Solution  

Notice the pattern in these two machines:

These machines below work in the same way. What goes into the machines? What comes out of them? Describe what each machine does.


 

Problem C6

Solution
