This product is designed to be used with inchworm connecting blocks. Each space on the bar graph is 1 inch tall so that students may connect the cubes they have for each color.
I prefer to put a predetermined number of each color into a paper bag for students to pull out and graph. This way each question can be answered (ex. Which two colors had the same amount of inchworms?)
The first graph already has each part of the graph written for the student as well as simpler questions. The second graph requires the student to fill in each part of the graph and also write their own question.
