Graphing Lesson Plan for 2nd Grade

A ready-to-teach graphing lesson for 2nd Grade. Everything below is classroom-tested structure: an objective, a 45-minute sequence, a way to check who got it, and 2 printable practice pages.

Approximately 45 minutes

Learning objective

Read and interpret data displayed in graphs and charts
Organize collected data into a bar graph or pictograph
Answer comparison questions using information from a graph

Materials

Creating Pie Charts - Book
Creating Pie Charts - Fruit
Pencils, and whiteboard space for the modeled examples

Lesson steps

1. Warm up together (5 min)
Open with a quick count-around or number talk that touches graphing. Ask students where they have seen graphing outside of math class. You are listening for who already has the vocabulary and who does not, so keep it light and let several students answer.
2. Model it (I do) (10 min)
Work two examples of graphing on the board, thinking out loud the whole way. Say the quiet parts: what you notice first, which step you do next, and why. Deliberately make one small error on the second example and let the class catch it.
3. Practice together (we do) (10 min)
Work three more problems as a class. Ask a different student to supply each step rather than the whole answer. If a step stalls, drop back to concrete objects or a drawing before moving on.
4. Independent practice (you do) (15 min)
Hand out "Creating Pie Charts - Book". Students work independently while you circulate. Note who is fluent, who is counting on fingers, and who has not started, because that grouping drives tomorrow's small group.
5. Close the loop (5 min)
Pull the class back. Ask one student to explain a problem they got right and one to name something that is still confusing. End on the confusion, not the success, so students learn that naming a gap is normal.

Check for understanding

Collect the practice pages and sort them into three piles: fluent, developing, and not yet. Any student in the third pile needs graphing retaught in a small group before the class moves on.

Differentiation

Extra support. Students who stall: pull them into a small group and rebuild graphing with concrete materials or a simpler text before asking for the written work again. Do not send the page home as homework, it will just rehearse the misunderstanding.

Extension. Students who finish early: ask them to write their own graphing problem for a partner to solve, then check the partner's work. Creating a problem is harder than solving one and it surfaces whether they really understand graphing.

Data and graphing

Questions teachers ask about teaching graphing

What graphing skills are expected in second grade?

Second graders should draw picture graphs and bar graphs with a scale of 1 to represent data sets with up to four categories (CCSS 2.MD.D.10). They should also solve addition and subtraction problems using information presented in bar graphs. Second grade adds graph creation to the first-grade focus on graph reading.

How do you teach bar graphs to second graders?

Begin with picture graphs (one picture = one unit) before introducing bar graphs. Teach students to label both axes, title the graph, and use a consistent scale. Start with a scale of 1 (each unit = 1 item) before introducing scales of 2, 5, or 10. Worksheets that present a data table and ask students to create a bar graph, then answer questions about it, combine creation and interpretation.

What questions should second graders answer from a graph?

CCSS 2.MD.D.10 expects second graders to answer: how many in each category, which has the most or fewest, how many more or fewer in one category vs. another (requiring subtraction), and what is the total. The how-many-more questions are where graphing intersects with arithmetic, making graphing a rich context for word-problem practice as well as data skills.
