Non-routine counting problems, Clip 6 of 8: Lollipop problem with Stephanie, Dana and Michael, part one [video]. Retrieved from https://doi.org/doi:10.7282/T3C82C0K
DescriptionThe sixth of 8 clips with second grade students focuses on Dana, Michael and Stephanie, one of several small groups within a whole-class session working on the lollipop problem. Researcher Amy Martino has given each group a copy of the problem statement and, after some disagreement, Stephanie insists that they must find the number of lollipops and bubble gums that would add to 63 cents. Each child suggests different amounts based on multiplication, but without successfully reaching the total of 63. As Stephanie says that she would prefer to add, the researcher notes that there are Unifix cubes. The children immediately count out 63 Unifix cubes and begin to construct stacks, some with 5 cubes linked together and others with 8. Stephanie begins to calculate stacks of 8 cubes. She asserts that two stacks would total 16 cubes and that two more stacks (of 8) would bring the total to 26 cubes. She then announces that these four lollipop stacks plus two stacks of 5 (bubble gums) would total 36, which she then pronounces to be the desired total. Note that the children's work on this problem continues in Clip 7 of this series.
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?
