Danielle predicts that the category with the most toys is the bears category. She checks her prediction by counting the number of toys in each group, lining them up in rows. She says her prediction was correct. Even though she counted, she does not use numbers to explain, instead indicating the length of the row of bears with her hands and stating that there are more bears.
Michael: Create a Graph
Michael creates a graph by placing the toys on top of a grid. This is not ideal because the toys are different sizes. The 13 bears end up being about the same height as the 9 cubes. Michael recognizes that they are about the same height and suggests writing numbers underneath the labels to clarify which category has the most.
Lucy: Create a Bar Graph
Lucy methodically colors a bar graph to show how many of each color of cube she previously sorted. Since the squares on the grid are larger than the connecting cubes, she explains that she will break the stacks apart and place one cube in each cell of the grid paper to ensure that she shades correctly. She is very expressive and metacognitive. Then, she reconnects the cubes and compares her cube stacks to her completed graph, which is an accurate representation.
Erica: Read a Picture Graph
Erica identifies the objects shown by a simple picture graph -- birds, cats, and dogs -- but then misinterprets the graph, believing it to show the heights of pets, not numbers of pets. The interviewer provides some guidance, prompting her to count the number of dogs and she does. This video clip is subtitled because Erica is quiet.
