New Jersey Grade 3 Math

The 2023 New Jersey data-literacy standards include asking a data-based question, collecting suitable responses, and reading scaled graphs. This activity focuses on the scaled-graph part. The original poll asks which of three classroom activities each child would choose, with exactly one choice per child.

Try this original activity

The display gives twelve votes for drawing, eight for puzzles, and four for building. Each block represents two votes. How many children answered? How many more chose drawing than building? How many fewer chose puzzles than the other two activities combined? Explain each calculation from the scale.

Work through the reasoning

The drawing row has six blocks, each worth two votes, so it represents 6 × 2 = 12 responses. The other rows represent 4 × 2 = 8 and 2 × 2 = 4. Adding the response counts gives 12 + 8 + 4 = 24 children. Drawing exceeds building by 12 − 4 = 8 votes. The six-block and two-block rows differ by four blocks, but those four blocks represent eight votes. Drawing and building together have 12 + 4 = 16 votes, so puzzles has 16 − 8 = 8 fewer than those categories combined. The total counts children because each child made exactly one choice. The final comparison needs two steps: combine the two other categories, then compare their total with puzzles.

Check the common mistake

Counting twelve blocks gives the number of symbols in the entire display, not the twenty-four responses they represent. Do not change the scale between rows or label a four-block difference as four votes. If children could choose more than one activity, the sum could count responses without counting distinct children. The stated one-choice rule matters. These are illustrative counts and do not describe preferences at a real New Jersey school.

Try a related case

Redraw the same data with one symbol representing four votes: drawing uses three symbols, puzzles two, and building one. The symbol counts change, but the response totals and differences remain the same. Then write a different data question and decide what responses would answer it. This extends the activity toward the question-and-collection expectations without treating the invented poll as collected classroom evidence.
