Sharing Boats
Division can ask how many equal groups fit. A remainder is what is left when there is too little to fill another whole group.
Before you try
Before you play, make a prediction: 17 ÷ 4 is… 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 9: Equal Groups, pages 128–148).

Try these ideas
- Make full groups, leave the remainder outside and check total = groups × size + remainder.
- 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
Division can ask how many equal groups fit. A remainder is what is left when there is too little to fill another whole group.
Seventeen items packed in groups of five make three full groups with two left. Make full groups, leave the remainder outside and check total = groups × size + remainder.
If the remainder is at least the group size, another full group can still be made.
This activity connects to Equal Groups, NCERT Class 4 maths, printed pages 128–148. 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: Pack 23 shells in groups of 5. Four full groups use 4 × 5 = 20 shells. Three shells remain. 23 ÷ 5 = 4 remainder 3; 3 is smaller than the group size.

Question 1 of 2
17 ÷ 4 is…
Which checks 29 ÷ 6 = 4 remainder 5?
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. Make full groups, leave the remainder outside and check total = groups × size + remainder. Ask the child to make a new example using paper, counters, household objects or a labelled sketch.
- Listen to the explanation. If the remainder is at least the group size, another full group can still be made. Ask “How could we check?” and encourage a second representation of the same idea.
