What this worksheet practices
2.OA.B.2 · Common Core Math · Grade 2
Operations & Algebraic Thinking
Children work on understanding what addition and subtraction mean, solving word problems with them, and building fluency with adding and subtracting.
How to use this worksheet
- 1
Do "Hundreds, Tens and Ones" before either regrouping sheet. A child who can say that 47 is four tens and seven ones will understand carrying; a child who cannot will memorise a procedure and forget it over the summer.
- 2
On "Counting Money", use real coins alongside the page. Coin values are arbitrary facts — the only way in is handling them.
- 3
For "Two-Step Word Problems", ask "what do we need to find out first?" before any calculation. Naming the hidden first step is the entire skill; the arithmetic is already easy by this point.
- 4
Print "Reading a Bar Graph" even if it looks easy. Data questions are heavily represented on second-grade assessments and are the ones children have practised least.
