Two of four parts are colored. My child says that is a half. Are they wrong?

No, they are right, and worth telling so. Two quarters and one half are the same amount, and noticing that is real fraction sense. This game names the picture by the pieces drawn on the screen, so with four parts on the bar the answer it wants is 2/4.

What does the bottom number of a fraction mean?

It tells you how many equal parts the whole was cut into, which also tells you how big each piece is. A bigger bottom number means more cuts and smaller pieces, so sixths are smaller than thirds. It does not count anything colored; that is the top number.

Do the parts really have to be equal?

Yes, and it is the one condition a fraction cannot do without. A pizza cut into four pieces where one is huge contains no quarters, because a quarter means one of four parts that all match. Every bar here is cut equally, but the question is worth asking elsewhere.

How to play

1A shape appears with some parts shaded, like three quarters of a pizza.
2Choose the fraction that names the shaded part.
3The trap is always the same: equal parts. Two shaded pieces of different sizes are not two of anything.
4Build a streak of correct matches.

Try a few

A bar is split into 4 equal parts. 3 of them are colored.
Answer: 3/4
Count every part first and ignore the colors: one, two, three, four. That four is the bottom number and it never changes however much is shaded. Now count only the colored parts: three. The single white part is a distraction, not a number to write down.
A bar is split into 3 equal parts. 2 of them are colored.
Answer: 2/3
Three equal parts means thirds, so the bottom is a 3 whatever else happens, and two colored makes the top a 2. Saying it in words first, two of three parts, puts the numbers in the order they must be written, and the choices with a 3 on top stop tempting.
A bar is split into 6 equal parts. 5 of them are colored.
Answer: 5/6
Sixths are narrow and easy to miscount, so check a second way. Only one part is white, so the colored amount is one part short of the whole bar. A whole bar is six sixths, and one less is five sixths. Two routes to one answer builds confidence.

Why this game helps

The most common fraction mistake is not about the numbers at all: it is thinking any two pieces make halves, or that the bottom number counts the shaded parts. A fraction only means something when the whole is split into EQUAL parts, and the denominator counts how many of those equal parts the whole was divided into, not how many are colored. Matching a shaded picture to its name, over and over, builds the habit of checking that the parts are equal first and reading the denominator as the size of the pieces. That is what turns a fraction from a pair of numbers into a quantity a child can reason about.

If your child finds this hard

The mistake children make first here is flipping the two numbers: a child sees three of four parts colored and writes 4/3. It comes from reading the picture in whatever order the eye moved, and the cure is a word habit rather than a rule. Have your child say it as a sentence before choosing, three of four parts, because the words come out in the order the fraction is written.

Watch for a child naming the white part instead of the colored one, which is counting unshaded instead of shaded. This game makes it tempting, since some of the bar is left white in every single round. Cover the white with your thumb and ask again. Right with the white hidden and wrong with it showing tells you the reading habit is what needs work.

A different kind of stuck is the child who is happy with halves and quarters and lost with thirds and sixths. That is a gap in experience more than understanding: halves and quarters are what folding paper in half twice gives you, and no amount of folding in half produces a third. Cut something real into three equal parts together and thirds stop feeling like a trick.
