What this worksheet covers
Set A of this grade 2 drill sheet holds twenty subtraction problems on one printable page, with the answer key on the page behind it. Two of the twenty column problems need regrouping and the rest do not, so the two cases are mixed rather than blocked and the numbers run as high as 19. Two problems from the middle of the page — "19 − 4" and "4 − 3" — show the range. Common Core 2.NBT.5 is the slot this page fills.
Skills practiced
The grade 2 subtraction sequence covers two-digit subtraction within 100 with regrouping, and mental subtraction of 10 and 100; this page sits inside it. Specifically, the problems practice grade 2 Subtraction Practice. Working the page asks a student to regroup past ten rather than counting up one at a time. Thirteen different answers appear across the twenty problems, so a student cannot copy one result down the page.
About the drill format
This drill runs 20 problems in a steady layout, so the eye never has to hunt for the next one; problem 7, "19 − 4" shows the level it holds. A page of same-shaped differences is where a borrowing method either settles or shows its cracks.
Set A, Set B and Set C
Set A is the original sheet, and Sets B and C were derived from it problem by problem: each number became a slot redrawn with the same shape, and every answer was recomputed exactly. Where Set A's problem 11 is "15 − 2", Set B's is "12 − 3".
How to use this worksheet
Sit alongside for this subtraction drill. At grade 2 the useful information is not the score but which of the twenty problems drew a pause. If more than a third of the twenty problems come back wrong, stop and step back a grade in subtraction rather than assigning Set B.
One mistake to watch for
Subtraction facts are recomputed by counting back one at a time. Watch problem 14 of this drill — "4 − 3" — for this one.
The relationship to addition has not been made explicit, so 13 − 8 is not being read as "8 plus what is 13".
Practice fact families as a unit, four equations at a time, and give unknown-addend problems alongside the subtraction ones.
