From Raw Responses to a Frequency Table
Lesson
Children often miscount when scanning a busy picture; encourage them to mark each face lightly in pencil as they count so no entry is skipped or double-counted. The true/false question in Q4 is a first nudge toward comparing totals rather than just reading them — worth pausing on the reasoning, not just the answer.
0–10Pose the problem: Samaira and Kabir collect data from 35 friends on TV-watching time. Ask children: if everyone gives you a different answer, how do you make sense of it all? Invite two or three quick suggestions, then show how categories help organise many raw responses into a neat table.
10–25Children open to the notebook picture and work on Let us Do, p.180 ("Complete the frequency table by counting children for each TV-watching duration...."), tallying faces in each duration category and writing counts in the table. Circulate and prompt careful one-to-one counting.
25–40With the completed table, children tackle Let us Do Q1–Q4, p.180 ("Answer 4 questions: how many watch more than half an hour...."). After individual work, invite responses to the true/false item and draw out reasoning: which row total is bigger and why does that matter?
Let us Do Q1–Q4, p.180 — Answer 4 questions: how many watch more than half an hour, less than two hours, more than two hours; true/false comparison of two-hour vs half-hour watchers.
A frequency table shows: ½ hr — 8 children; 1 hr — 12 children; 1½ hr — 6 children; 2 hrs — 5 children; more than 2 hrs — 4 children. How many children watch TV for less than 2 hours?
- A 20
- B 26
- C 31
- D 35
B. 26
What each wrong option reveals
- A Choosing 20 reveals the student added only two categories (e.g. 8 + 12) and missed the 1½ hr row.
- C Choosing 31 reveals the student included the 2-hrs category (8 + 12 + 6 + 5 = 31), misreading 'less than 2 hrs' as 'up to and including 2 hrs'.
- D Choosing 35 reveals the student added all five categories, ignoring the 'less than 2 hours' condition entirely.
