Towers Group Sharing, Clip 3 of 6: Guessing how many towers can be built three cubes high, continued [video]. Retrieved from https://doi.org/doi:10.7282/T30K26ZR
DescriptionIn this clip, researcher Alice Alston continues a discussion started in the previous clip in this series. The discussion centers on how many towers can be built three cubes high when selecting from two colors. Some students guess that there would be the same number of towers built from three cubes as there are from four. When questioned why she believes the number of towers would be the same, Stephanie answers that removing one block from a tower would not “change the whole thing [because] it’s just going to be one less”. Other students offer their opinions; one says there would be a “lot more”, some say there would be the same number, and some say there would be fewer. After hearing the students’ guesses, the researcher asks the students to create towers three high and see how many there are, reminding the students that all the towers must be different.
