Fraction Bridges
Compare fractions of the same-sized whole. More equal pieces make each piece smaller. Equivalent fractions cover the same amount.
Before you try
Before you play, make a prediction: Which is larger for the same whole? 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 5: Sharing and Measuring, pages 62–79).

Try these ideas
- Compare equal-length bars, then look for fractions that cover equal lengths.
- 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
Compare fractions of the same-sized whole. More equal pieces make each piece smaller. Equivalent fractions cover the same amount.
One half is the same as two quarters and is greater than one quarter. Compare equal-length bars, then look for fractions that cover equal lengths.
Always compare the same-sized whole. Half of a small cake need not exceed a quarter of a much larger cake.
This activity connects to Sharing and Measuring, NCERT Class 4 maths, printed pages 62–79. 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: Compare 1/2 and 1/4 of equal-sized cakes. A half can be split into two quarters. One half is two quarters, which is larger than one quarter.

Question 1 of 2
Which is larger for the same whole?
Which fraction is equivalent to 3/4?
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. Compare equal-length bars, then look for fractions that cover equal lengths. Ask the child to make a new example using paper, counters, household objects or a labelled sketch.
- Listen to the explanation. Always compare the same-sized whole. Half of a small cake need not exceed a quarter of a much larger cake. Ask “How could we check?” and encourage a second representation of the same idea.
