Life Sized Number Lines

During our last few weeks of school, we are working on reviewing math concepts and building up an understanding of numbers using number lines. We started out practicing skip counting in various ways, including ways that are not skip counting starting at 0, giving students a chance to look at counting by 5's and 10's in different ways. Next we started putting these skip counting patterns onto a number line as increments. Now we are using number lines to explore operations. We have reviewed addition and subtraction on a number line and now we will make the connection to an introduction to multiplication.

One of my students' favorite projects was putting together life sized number lines. For this project I had every student come up with their own number and write these numbers on white index cards. We lined up the numbers in order from least to greatest. Then, split the students in half. Each group used their numbers to create their own number line with increments. 

We first brainstormed these number lines on scrap paper and then once I conferenced with each group, the students wrote out their increments on colored index cards. These colored index cards were glued onto butcher paper to create life sized number lines. Once the number lines were made, the students placed their number cards onto the number lines. When their number lines were complete, I gave each group a few extra number cards and asked them to add these numbers to their number line as well.

The students loved working on these group projects and the lifesized number lines have been a great teaching tool. We have used these life sized number lines to compare numbers and to work on operations. From my observations on this project, I was able to create three differentiated groups for my Prove it, Solve it, Fix it Tiered Activities for Number Lines.

What math activities are you working on during these final months of the year?
