Grade 2 Math Lesson Plan: Data & Graphs — 4 Lessons with Timings

Learning Objectives

• Sort objects into groups and count each group.
• Draw tally marks in bundles of 5 and count them by 5s and 1s.
• Make a tally chart from a survey and write the totals.
• Read a picture graph with a key (each picture = 1) and finish one from a tally chart.
• Read vertical and horizontal bar graphs with a scale of 1 and draw bars from a tally chart.
• Find the most and the fewest on a graph.
• Answer "how many more / fewer?" by subtracting and "in all?" by adding.

Lesson Procedure

• Teach the four lessons in order. Each lesson table shows the stage, minutes, what the teacher does, what students do and the matching PowerPoint slides. Lesson 1: sort and count, tally marks, a tally chart from a survey. Lesson 2: parts of a picture graph, reading it, finishing one from a tally chart. Lesson 3: parts of a bar graph, reading across to the scale, drawing bars. Lesson 4: most, fewest, how many more / fewer, in all, the "Ploy adds" mistake and a class survey. Use the optional fifth lesson for review and the test. Print the templates and survey cards before Lesson 4.

Assessment

Use the exit tickets after each lesson, whiteboard answers during lessons, and the Quick Quiz or Unit Test after the unit.

Differentiation

Support: Let children sort and count real objects first and tick each one as they count. Give them a counter to move along each row of a picture graph and a ruler to read bars. Start with 3 groups and numbers under 10. Keep the Data Helper poster on the desk. Give sentence frames ("___ children chose ." " got the most votes." "___ more children chose ___ than ___."). Pair a child who is new to English with a partner who models the sentences.
Extension: Solve the worksheet Challenge (find a missing number from a total), write 3 questions about a graph for a partner, make a picture graph where each picture = 2, or survey another class and compare the two graphs. Fast finishers can play Graph Detective (Compare mode).

Classroom Activity Ideas

• Human graph: children stand in lines by their favourite fruit, then the class counts each line and makes a tally chart.
• Cube towers: each child adds one linking cube to the tower for their choice; the towers become a real bar graph.
• Daily weather: add one tally mark each morning and make a bar graph at the end of the month.

Teacher Tips

Collect real data from your own class before you show any printed graph. Keep one class survey (for example "How do you come to school?") on the board all week and show it as a tally chart on Day 1, a picture graph on Day 2 and a bar graph on Day 3. Children then see that all three show the SAME numbers. Two habits stop most mistakes: say "the fifth line goes across" every time children draw tally marks, and read bars with a ruler from the top of the bar across to the scale. Before every question, ask "Add or subtract?" — "how many more?" means subtract (8 − 6 = 2), not add.
