Number lines are a great visual tool. There are many different types of numberlines that can provide a scaffold into deeper understanding. You want to use numberlines so that students have visual models and understanding of the relationships between numbers (see http://thinkmath.edc.org/index.php/Number_Line ). Numberlines provide visual scaffolds so students can picture what they are doing. Numberlines can be used to teach counting, skip counting, even and odd numbers, rounding, positive and negative integers, fractions, decimals and time. Here are a some links to a few good resources by category.
