Worked example · Grade 4 Decimals

Rosa ran 8.5 km on Saturday and 5.7 km on Sunday. How many more kilometers did Rosa run on Saturday?

  1. The question compares two amounts ("how many more"), so subtract the smaller from the larger.
  2. Line up the decimal points: 8.5 − 5.7. Think in tenths: 85 − 57 = 28 tenths, which is 2.8.
  3. So the answer is 2.8 kilometers.

Answer: 2.8

Worked example · Grade 6 Fractions

1 1/6 ÷ 4/5 = ?

  1. Write 1 1/6 as an improper fraction: 1 × 6 + 1 = 7, so 1 1/6 = 7/6.
  2. Keep the first fraction, change ÷ to ×, and flip the second: 4/5 becomes 5/4.
  3. 7/6 ÷ 4/5 = 7/6 × 5/4.
  4. Multiply the numerators: 7 × 5 = 35. Multiply the denominators: 6 × 4 = 24.
  5. That gives 35/24.
  6. 35/24 is more than 1 whole: 35 ÷ 24 = 1 with 11 left over, so 35/24 = 1 11/24.
  7. So 1 1/6 ÷ 4/5 = 1 11/24.

Answer: 1 11/24

Frequently Asked Questions

Why are fractions so hard for kids to learn?

Fractions contradict many whole number rules children have learned: a larger denominator means smaller pieces, multiplying can make numbers smaller, and two different-looking fractions can be equal. Using visual models (fraction bars, circles, number lines) bridges this conceptual gap effectively.

What grade do kids start learning fractions?

Basic fraction concepts (halves, quarters) begin in 1st-2nd grade. Formal fraction operations start in 3rd grade with equivalent fractions and comparison. Adding/subtracting fractions with unlike denominators comes in 5th grade, and fraction multiplication/division continues through 6th grade.

What is the best way to teach fractions at home?

Start with real-world examples: cutting food into equal parts, measuring cups while cooking, dividing groups fairly. Use fraction bars or circles to visualize comparisons. Progress from concrete (physical objects) to pictorial (drawings) to abstract (numbers only). Practice equivalent fractions extensively before operations.
