Using Numberlines in Guided Math Groups

Posted on November 6, 2010. Filed under: Graphic Organizers, Guided math, Manipulatives | Tags: |


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.

Hi Dr. Nicki,
First of all, the rationale for using number lines from the ThinkMath curriculum is a resource which all teachers should read. We use the ThinkMath curriculum at Nathan Hale in New Haven. It took a couple of years for teachers to get comfortable with the approach, but it is working for us. As with all math programs, the teachers pull from many resources to design lessons. Thank you for the plentiful number line resources. I have a question. How can I teach what number comes before or after a bigger number, such as ____ 246 ______ with a number line? It really gets tricky when the numbers are _____,190,_____ or _____, _____ 131. I know I can display parts of a number line. I just thought you might have a trick. The students automatically want to count by tens. Why?? Wonderful “stuff”.

Hi Lisa,
I would have them look at number lines and number grids and place their fingers on the number. This makes them focus. Also, have them count within the range of numbers in their heads so they can think about what logically comes before or after. If you practice with number puzzles, where they have number grids with blank spaces that they have to fill in, this helps as well. See examples on the hundreds grid post.
Happy Mathing,
Dr. Nicki
