What this worksheet covers

Set A of this grade 4 timed drill sheet holds 72 subtraction problems on one printable page, with the answer key on the page behind it. What makes this set particular: ten of the 72 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 900. Two problems from the middle of the page — "8 - 2" and "18 - 12" — show the range. The sheet sits inside Common Core 2.OA.2, in the grade 2 Operations & Algebraic Thinking strand.

Skills practised

At grade 4, subtraction is about the standard algorithm on four- and five-digit numbers, and this sheet takes one slice of that. The skills on the page: subtraction facts within 20 and subtracting hundreds mentally. Working the page asks a student to carry or borrow across place-value columns without losing a digit. 22 different answers appear across the 72 problems, so a student cannot copy one result down the page.

About the timed drill format

With 72 short problems such as problem 25, "8 - 2" and a timer box, this page measures recall rather than method — write the time down, and aim to beat it on Set B. Subtraction facts are the slowest of the four to become automatic; a timer shows which ones are still being counted.

Set A, Set B and Set C

The three sets come from the same generator with three different seeds: same skill, same layout, fresh numbers, and an answer key computed with the problems. Where Set A's problem 37 is "16 - 6", Set B's is "14 - 5".

How to use this worksheet

Work the 72 problems straight through, then check against the key together rather than handing it back marked; asking a grade 4 student to find their own subtraction error teaches more than seeing it circled. If more than a third of the 72 problems come back wrong, stop and step back a grade in subtraction rather than assigning Set B.
