KitchenTableMath supplies urges readers to compare and contrast three problems from the last page of three different fifth-grade textbooks:
Primary Mathematics 5B (U.S. Edition):
18. A fish tank is 2/5 full after Sara poured 14 gal of water into it. What is the full capacity of the tank in gallons?
Saxon Homeschool Math 6/5 3rd Edition:
Change each of these base 10 numbers to base 5:
Math Trailblazers Grade 5:
4. Write a paragraph comparing two pieces of work in your portfolio that are alike in some way. For example, you can compare two labs or your solutions to two problems you solved. One piece should be new and one should be from the beginning of the year. Use these questions to help you write your paragraph:
Which two pieces did you choose to compare?
How are they alike? How are they different?
Do you see any improvement in the newest piece of work as compared to the older work? Explain.
If you could redo the older piece of work, how would you improve it?
How could you improve the newer piece of work?
Of course Trailblazers must have math-ish problems on earlier pages, but it is a constructivist curriculum.
