One of my favorite math units is to teach graphing skills. Graphing in 2nd grade focuses on being able to read and interpret bar graphs, picture graphs, and line plots. Students also need to be able to create these graphs from data collected. I love having my students practice these skills with fun and hands-on activities!

Books to Teach Graphing Skills
Here are a few books you can use to teach graphing skills:
- The Great Graph Contest by Loreen Leedy
- Tally O’Malley by Stuart Murphy
- Lemonade for Sale by Stuart Murphy
Teach Graphing Skills with Objects
Students can create their own pictograph by using the little erasers found in the Target Dollar Spot or other math manipulatives. For some students, it helps their understanding to be able to manipulate and move the items on the graph.
Creating Class Graphs
When I first introduce graphing to my class, we create a lot of graphs together. I pose a question for the class and then we take the data from their responses to create the bar graph or pictograph (whichever we’re focusing on at the moment). For both of these types of graphs, we talk about how they focus on categorical data.
This can also be a great way to teach graphing skills and tie in cross-curricular topics. For your data, you can ask students a question about something in science or social studies to tie in different subject area.
During our data analysis unit, we spend a lot of time making observations. In addition to students being able to read the graph and answer specific questions, I also like them to just make their own observations. I will often set up a blank piece of anchor chart paper, we’ll analyze a graph, and students will just share out what they notice. This is another great way to check for understanding.
I had a hard time finding graphing practice that had the types of questions and graphing data I was looking for, so I created some of my own. For independent practice, I have students just read and answer questions from the graph and then also use data to create their own graphs. I also wanted to extend the activity for some students by bringing in two sets of data to make it more challenging. If you’re looking for some graphing practice already created for you, check out my graphing resource.
Students always enjoy activities that have to do with food – so why not bring food into graphing! Each year, I love to have my students graph Skittles. I put a handful of Skittles in a ziploc bag and then students have to sort the colors, create a graph, and then answer questions. This is a fun, hands-on way for them to practice.
Line plots always tend to be trickier for students. Since line plots are dealing with numerical data, not categorical, they sometimes get a little tripped up. I again create some line plots together. One question I alway start with is – How many years have you been at our school? We also go over the importance of carefully labeling the line plots so we and others can interpret it.
Students then go on to interpret line plots and create them themselves.
Create Your Own Graph Project
At the end of our graphing unit, after we have learned about bar graphs, picture graphs, and line plots I love to have the class work on a culminating project. This project can be done individually or in a group.
Students get to create their own survey question and then survey they class. As they are surveying, they record the results and then create the graph that matches their data (categorical – bar graph or picture graph, numerical – line plot). When they are finished, they come up with a list of observations that they’ve made from their graph and present it to the class.
