How to Teach Fractions at Home with Things You Already Have

By Fieldbook Learning

Fractions are where many children first feel that math has stopped making sense. The good news is that fractions are about sharing, folding and measuring, so the best teaching tools are already in your kitchen and recycling bin. This post gives you a sensible order, a short list of materials and the misconceptions to watch for.

The big ideas, in order

  1. Equal parts. A fraction describes equal parts of a whole. Two unequal pieces are not halves.
  2. Naming parts. The bottom number (the denominator) tells how many equal parts the whole is cut into. The top number (the numerator) tells how many of those parts you are talking about. See the full definition of fraction.
  3. Size. More parts means smaller parts. One-eighth is smaller than one-fourth.
  4. Equal fractions. Different fractions can name the same amount: one half and two fourths. This is equivalent fractions.
  5. Comparing and ordering. Which is more, 3/4 or 2/3?
  6. Fractions on a number line. Fractions are numbers, not only pieces of a pizza.

Teach them in this order and do not rush the early ones. Most trouble later comes from skipping step 1 or 3.

What you need

  • Paper (any), scissors, a marker
  • An egg carton (12 cups) or a muffin tin
  • Measuring cups and spoons
  • A ruler or tape measure
  • Food that cuts into parts: a banana, a sandwich, a sheet of crackers, a block of chocolate with squares
  • Coins, buttons or socks for sets

Activity 1: Fold paper strips

Give a child several same-size paper strips. Leave one whole. Fold one in half and cut. Fold another into four equal parts, another into eight. Ask them to label each piece (1/2, 1/4, 1/8) and stack the pieces below the whole.

Now they can see everything: two quarters fit exactly where one half does, and eight eighths make a whole. Keep these strips in an envelope, because you will use them again.

If you would rather print a set, the free fraction strips chart gives you a labeled wall from halves to twelfths. For a screen version, try the fraction wall tool.

Fix to watch for: children folding unevenly. Ask “how do you know the parts are the same?” and have them lay one piece on top of another.

Activity 2: Share food fairly

Ask a child to share a sandwich between two people so that it is fair, then four, then three. Three is hard to fold, which is a good point: some fractions are tricky. Discuss: “Is the piece you have the same amount as mine, even if it looks different?” A square cut in half as two rectangles or two triangles is still halves.

Do the same with a set: share 12 crackers among 4 people. What fraction of the crackers does each person get? Fractions can describe parts of a group, not just parts of a single shape.

Activity 3: The egg carton

A carton of 12 is a natural fraction tool. Ask: “Color half of the cups.” (6.) “Now color a third of the cups with a different color.” (4.) Count again: “What fraction is left uncolored?” Twelve is a friendly number because it splits into halves, thirds, fourths, sixths and twelfths.

Then connect: 6 of 12 is the same as 1/2; 3 of 12 is the same as 1/4; 4 of 12 is the same as 1/3. That is how equivalent fractions start to make sense, with no rules to memorize.

Activity 4: Measuring cups

Fill the 1/4 cup and pour it into the 1 cup. How many does it take to fill the cup? Now try the 1/3 cup and the 1/2 cup. Ask: “How many 1/4 cups fill one 1/2 cup?” (2). “How many 1/8 cups?” (4, if you have one). It is real measurement, and it shows why baking is a good place to meet fractions.

Activity 5: Circles

A paper circle folded into halves, fourths and eighths shows fractions as parts of a round shape, like a pie. Ask children to compare 3/4 of a circle to 3/8 of the same circle. The fraction circles tool does this on screen, and works for a quick check when you do not have paper to hand.

Activity 6: Fractions on a ruler

Use a ruler marked in inches (or a tape measure). Find 1/2 inch, 1/4 inch, 3/4 inch. This shows children that fractions live between whole numbers. Draw a number line from 0 to 1 and ask them to place the paper strips on it, fold by fold.

Common misconceptions

  • “Bigger bottom number means a bigger fraction.” With the strips: 1/8 is much smaller than 1/2. Put them side by side every time.
  • “1/3 + 1/3 = 2/6.” Adding fractions with the same denominator keeps the parts the same size, so you add only the count of parts: 1/3 + 1/3 = 2/3. Use strips to show it.
  • “A fraction is two separate numbers.” Remind children it is one number: a point on the number line.
  • Unequal parts called halves. Always ask: are the parts equal?

How long should it take?

Short and often beats long and rare. Ten or fifteen minutes of folding and talking, three or four times a week, is enough. Move to the next idea only when the child can explain the last one in their own words and show it with a model.

What to do next

Once children are comfortable with the concrete ideas, move to pictures and then to symbols. Browse everything we have on the fractions topic page, which collects lessons, printable packs, practice and tools in one place. The free practice section has fraction skills by grade, and the glossary pages above give child-friendly definitions you can read together.

Frequently asked questions

At what age should children learn fractions?

Informal ideas, such as halves and fourths, begin in Kindergarten and Grade 1. Formal work on fractions with numerators and denominators typically starts around Grade 2 or 3 and continues through Grade 6 or beyond, depending on your curriculum.

My child can do the worksheet but cannot explain it. Is that a problem?

It is a sign to go back to a model. If they can show it with strips or a carton and say why, the symbols will follow.

Do we need special materials?

No. Paper, a ruler and food from the kitchen cover almost everything.
