In my fourth grade classroom, on Fridays, I like doing my math block a little differently. My favorite things to do during this time are whole group or small group math activities, with something other than what we typically do during math time.
I came up with the idea of giant graphs as something to do on one of these Friday math times. I find that most of the time, students know how to look at a graph and see which bar is higher than the other or some other simple comprehension piece, but they don’t know how to construct a graph from the beginning or know which type of graph is best to use in different circumstances.

Implementing giant graphs in your classroom is a way for students to understand the full workings of graphs – what types to use, how to choose a graph scale, add labels, and then construct the graph. In addition, students get to do all of the data collection themselves so that the graph actually has some meaning for them, rather than just giving them a set of numbers that they don’t know anything about.
Beyond the math giant graphs are collaborative, and the students work together as a whole group to construct each graph. This means they have to know how to communicate with each other in order for the project to be successful.
Probably my favorite part, though, is that it is teacher-guided–but not teacher-led. The teacher’s role is to help students think about certain parts of the graphing process and help them be successful, but not to tell them what to do. This even includes not telling them which type of graph to make. Allowing students to figure out some of these things for themselves (even if they are unsuccessful on the first attempt) allows them to gain a deeper understanding of how graphs work and how to be successful in a group situation.
Making the graph grid takes a little time, but after it’s made, it can be used for a number of weeks. You’ll need a fairly large space so that the students can walk around the grid. If you don’t have a large space in your classroom, think outside the box and use the field, hallway, or playground space.
Take some 8 1/2″ x 11″ paper and lay out the edges of a grid on the floor. I do 7′ x 10′, but you can do whatever size works for your space. Then take some masking tape (you’ll need around two rolls) and tape out a grid. Spacing out the paper helps so that you do not need to measure anything. I found that making the grid only takes 15 minutes or so. If you want to, you could also have your students make the graph grid.
There are many topics you can use to create the graphs. Once you have constructed a few graphs, you may have the students choose their own topics to graph. The best topics would go with things that you’re already doing in the classroom so that the data is meaningful to the students. Here are some possibilities:
- favorite hot lunch
- types of transportation to and from school
- days with/without precipitation
- number of siblings
