Non-routine counting problems, Clip 7 of 8: Lollipop problem with Stephanie, Dana and Michael, part two [video]. Retrieved from https://doi.org/doi:10.7282/T37H1M8V
DescriptionIn the seventh of 8 clips with second grade students, Dana, Michael and Stephanie, one of several small groups within a whole-class session, continue their work on the lollipop problem. (See Clip 6 of this series for their progress toward a solution before this point.) In explaining what they thought was a solution to the researcher, Amy Martino, the three students realize that they have not reached the required total of 63 cents. They continue to use the Unifix cube stacks in different combinations for some time without finding a total that will work. Finally, they begin counting the stacks of 8 to six stacks, continue with two stacks of five to a total of 58 and Dana counts the five remaining cubes and recognizes that this gives the desired total of 63.
The Problem Statement:
Michelle spent 63 cents on candy. Lollipops
are 8 cents each and bubble gum pieces are 5 cents each.
How many of each kind did she buy?
