What each grade’s quiz covers
| Grade | Question types | Learn it |
|---|---|---|

| Grade 4 (class 4) | Equivalent fractions, comparing any fractions, adding and subtracting like fractions, mixed numbers, fraction × whole number, fraction of a number | 4th grade fractions |
| Grade 5 (class 5) | Unlike denominators, mixed number sums with regrouping, multiplying fractions, fractions as division, dividing by whole numbers | 5th grade fractions |
| Grade 6 (class 6) | Dividing fractions, multiplying, simplest form, fractions to decimals, mixed numbers, word problems, comparing | 6th grade fractions |
What is in the quiz?
Pick a grade and answer 10 mixed questions: pictures to name, fractions to compare, sums, mixed numbers, products, quotients and word problems. Each answer is marked straight away with a hint, and Play again gives a fresh quiz every time.
Fraction answers go in stacked boxes, a top box and a bottom box, just as fractions are written on paper. Mixed numbers have a third box for the whole number. Any equivalent answer is accepted, so 2/4 and 1/2 both count, unless the question asks for simplest form.
The hints show a method, not just the answer. A missed 3/4 − 1/6 shows the common denominator 12, and a missed division shows the keep, change, flip step.
How to use the quiz
- As a check-up: take the quiz for your child’s grade once a week and note the score.
- Read the hints: every wrong answer shows how to work it out. Talk through one together.
- Go back a grade if the score is under 6 out of 10. Many grade 5 mistakes are really shaky grade 4 equivalent fractions.
- For one skill at a time, use the fraction practice tool and pick a skill.
- To track progress step by step, use the fraction levels.
You can link straight to a grade: grade 3 · grade 4 · grade 5 · grade 6.
What the score means
| Score | What to do next |
|---|---|
| 9 or 10 | Secure. Try the next grade, or the next fraction level. |
| 7 or 8 | Nearly there. Read the hints for the misses and retake in a few days. |
| 6 or less | Go back to the lessons for the question types missed, or try the grade below. |
Look at which questions were missed, not just the total. Three misses on mixed numbers need a different fix from three misses on comparing.
The errors the quiz shows up
Fraction mistakes follow a few patterns. Spotting the pattern tells you what to teach next.
- Adding straight across: 1/2 + 1/3 = 2/5. Find a common denominator first. See common denominators.
- Bigger denominator, bigger fraction: 1/8 > 1/4. Bigger denominators mean smaller pieces. See comparing fractions.
- Changing only the top: 2/3 = 4/3. Multiply top and bottom. See equivalent fractions.
- Borrowing 10: 5 1/4 = 4 11/4. One whole is 4/4. See subtracting mixed numbers.
- Flipping the wrong fraction when dividing. See dividing fractions.
