Desk Detectives
A row runs across and a column runs up and down. Labels tell where counting begins. Position clues locate an object even when the objects move.
Before you try
Before you play, make a prediction: With rows numbered from the top, is row 1 above row 2? 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 2: Hide and Seek, pages 24–33).
Something went wrong

Try these ideas
- Use the printed row and column labels rather than guessing the starting corner.
- 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 row runs across and a column runs up and down. Labels tell where counting begins. Position clues locate an object even when the objects move.
Row 2, column 3 means the cell where those two labelled tracks meet. Use the printed row and column labels rather than guessing the starting corner.
Read the labels: some maps count rows from the bottom, while this game labels them from the top.
This activity connects to Hide and Seek, NCERT Class 4 maths, printed pages 24–33. 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: Where is row 3, column 2 in a grid labelled from the top and left? Move down to the row labelled 3. Move across to the column labelled 2. Their intersection is the required cell.

Question 1 of 2
With rows numbered from the top, is row 1 above row 2?
A column of four cubes has how many squares in its top-view footprint?
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. Use the printed row and column labels rather than guessing the starting corner. Ask the child to make a new example using paper, counters, household objects or a labelled sketch.
- Listen to the explanation. Read the labels: some maps count rows from the bottom, while this game labels them from the top. Ask “How could we check?” and encourage a second representation of the same idea.
