This resource is a remix from Illustrative Mathematics https://tasks.illustrativemathematics.org/content-standards/tasks/1081. Suggested Modifications: It is imperative that students in their early ages of mathematics education be introduced to the idea of the number line that makes sense. In other words, they usually count the tick marks on the number line which leads to an inaccuracy in the algorithm. To help them better understand number lines, the suggestion is to introduce the idea number paths which is another way of looking at a number line. To help better facilitate the lesson, I have added a downloadable document student activity that can be used in cooperative learning groups to facilitate mathematical discourse. This activity also encourages literacy in the curriculum.   

This video is part of the Learn and Grow with WHRO TV series. Watch Patty Larson teach about numeral order 0-10 and how to use a number path.
