I created these number line sticks in 2001 when I could not find any vendor that carried a vertical number line. My students struggled with adding and subtracting negative and positive numbers and this helped them visualize and internalize the skill.
The number line is an easy model for students to understand. It helps them visualize operations. Young children naturally recognize marks on a number line as visual representations of the mental images that most people have when they learn to count and develop understanding of number relationships. Students are more engaged in math problems when they can jump along the number line in ways that resonate with their intuitions.
