Survey Station
A survey needs a clear question and one consistently recorded response from each person. Tally marks group five as four strokes crossed by a fifth.
Before you try
Before you play, make a prediction: A group of five tally marks is drawn as… Explain what you expect and what part of the model will help you check it.

What happened?
Move a control to see what changes and why.
The game practises one idea at a time with simple drawn pictures. Check the same idea with real objects and your NCERT textbook (Chapter 14: Data Handling, pages 203–208).

Try these ideas
- Read each response once and send it to the correct tally column.
- Try a new puzzle with ↻. Describe what changed and which mathematical rule stayed the same.
- Complete a round, then explain your method before you move to the next one.
Why it works
A survey needs a clear question and one consistently recorded response from each person. Tally marks group five as four strokes crossed by a fifth.
Seven votes are one group of five and two more. The sum of category counts equals all responses. Read each response once and send it to the correct tally column.
Use one clear question and consistent categories. Do not record the same response twice.
This activity connects to Data Handling, NCERT Class 4 maths, printed pages 203–208. Use the picture or objects to explain each step before relying on a calculation. The game practises one part of the chapter at a time; the other three activities extend the chapter’s ideas.
Worked example: A fruit survey gives apple, banana, apple, orange, apple, banana. Make the counts. Record each response in its category once. Apple has 3, banana 2 and orange 1. Their sum is 6, matching the six responses.

Question 1 of 2
A group of five tally marks is drawn as…
Counts in three categories are 5, 8 and 7. How many responses in total?
Explain it in your own words
What changed? Why did it happen? Where might you notice this in everyday life?
For parents & teachers
- Try with everyday materials. Read each response once and send it to the correct tally column. Ask the child to make a new example using paper, counters, household objects or a labelled sketch.
- Listen to the explanation. Use one clear question and consistent categories. Do not record the same response twice. Ask “How could we check?” and encourage a second representation of the same idea.
