FAQ
What subtraction do 2nd graders learn?
Second grade subtraction centers on subtracting within 100 — including two-digit problems that require regrouping (borrowing), such as 62 − 47 = 15. This is the core standard CCSS 2.NBT.5. Students also keep building fluency with subtraction facts within 20 (2.OA.2) and begin subtracting three-digit numbers within 1,000 (2.NBT.7).
What is regrouping (borrowing) in subtraction?
Regrouping happens when the top ones digit is smaller than the bottom one, so you “borrow” a ten — for example 62 − 47: you can’t take 7 from 2, so borrow a ten to make 12 − 7 = 5, leaving 5 tens − 4 tens. The stacked (column) layout lines digits up vertically so children can practice borrowing step by step.
What is a missing-number subtraction problem?
A missing-number problem leaves a blank in the equation, such as 62 − ▢ = 15. Solving it pushes students to see subtraction as an unknown-addend problem — a key reasoning skill that supports the addition and subtraction relationship (CCSS 2.OA.1). Turn it on with the “Missing number” option.
