Number lines are an important visual representation of foundational number concepts. They show up at every level and across mathematical domains. According to the National Research Council in Adding It Up: Helping Children Learn Mathematics (2001), "because it can serve as a tool for simultaneously representing whole numbers, integers, and rational numbers, teachers and researchers should explore effective uses of the number line representation when students learn about operations with numbers, relations among number systems, and more formal symbolic representations of numbers" (p. 418). [1] 

In this half-day, face-to-face workshop, we will look at how number lines can help students develop these basic concepts and how they can be applied to real world, career, and mathematical contexts. You will have the opportunity to examine and discuss student work and explore number line activities that could be used in the classroom.  

According to Boaler et al. in Seeing as Understanding: The Importance of Visual Mathematics for our Brain and Learning (2016), “It seems possible that visual mathematics may contribute to equity, in valuing students’ thinking in different ways, as well as encouraging deep engagement, as we have found all students to be excited to see math ideas, and from there they have developed higher levels of understanding and performance.” (p. 10). Not only does her team suggest that visualizing math helps all students (including LD students) to better understand math concepts, they also found when teachers were given visual experiences they gain insights into mathematical concepts as well.
