Session 10, Grades K-2, Part C:
More Problems That Illustrate Algebraic Thinking

In This Part: Strips and Balancing Blocks | Shape Machines | Number Machines
Mystery Machines | Two-Steppers

For each of the following problems, answer the questions below:


What algebraic content is in the problems?


What content does it prepare students for later?


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


How would your students approach this problem?


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


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

Problem C7


Notice the pattern in these two machines:

For each of the number machines below describe what goes in or what goes out, then explain how the machine works.


Problems adapted from Groundworks: Algebraic Thinking, Grade 1 and Grade 2, by Carole Greenes and Carol Findell (New York: Creative Publications, Wright Group/McGraw-Hill, 1998).
