- The development of computational proficiency
- The understanding of mathematical reasoning
I would give this quiz at the end of the class so that they can leave when they finish and not have to sit around and wait. Also, doing it at the end of class instead of before a break means that students who compute more slowly do not have their break time penalized.
I can also see how this can also be an instructive tool. For example:
- 85 + 74 = ???
- (80 + 5) + (70 + 4) = ???
- (80 + 70) + (5 + 4) = ???
By giving problems that are suggestively sequential, I can introduce various aspects of arithmetic that will become relevant to their future algebraic manipulations. It could also be used as a starting point for a discussion for the next class period. I'll definitely have to take a closer look at the structure of the textbook to see how effectively such a scheme could be woven into the material.
