This reviewer covers the DepEd Most Essential Learning Competencies (MELC) in Grade 2 Mathematics. Master each topic below to prepare for quizzes, periodical tests, and assessments.
Numbers up to 1,000
Read, write, compare, and order numbers up to 1,000. Master place value: hundreds, tens, and ones.
| Number | Hundreds | Tens | Ones |
|---|---|---|---|

Expanded form helps: 346 = 300 + 40 + 6. This makes adding big numbers much easier.
Addition and Subtraction with Regrouping
Add and subtract 2- to 3-digit numbers with regrouping (borrowing and carrying).
