This reviewer covers the DepEd Most Essential Learning Competencies (MELC) in Grade 3 Mathematics. Master each topic below to prepare for quizzes, periodical tests, and assessments.
Whole Numbers up to 10,000
Represent, compare, order, and round numbers up to 10,000, plus ordinal numbers to 100th and money up to ₱1,000.
| Place | Thousands | Hundreds | Tens | Ones |
|---|---|---|---|---|
| 4,725 | 4 | 7 | 2 | 5 |
To round to the nearest ten, look at the ones digit: 5 or more rounds up, 4 or less rounds down. 47 → 50, 43 → 40.
The Four Operations
Add and subtract with regrouping, and master multiplication and division of whole numbers, then solve word problems.
Learn the multiplication tables up to 10. Division is the inverse of multiplication.
In word problems, key words help: "in all / total" → add; "left / fewer" → subtract; "each / per" → multiply or divide. But always picture the situation, not just the keyword.
Fractions
Understand fractions as part of a whole and part of a set. Compare and order similar fractions.
With the same top number (numerator), the fraction with the smaller bottom number is bigger — because the whole is cut into fewer, larger pieces.
Measurement and Data
Measure length (cm, m), mass (g, kg), and capacity (mL, L) using standard units. Tell time and read simple bar graphs and tables.
| Quantity | Small unit | Big unit |
|---|---|---|
| Length | centimeter (cm) | meter (m) |
| Mass | gram (g) | kilogram (kg) |
| Capacity | milliliter (mL) | liter (L) |
