Grade 4 multiplication missing number sheet: 24 problems on two-digit by one-digit multiplication.
Three different problem sets — same skill, same layout, fresh numbers.
Find the number that belongs in each blank.
Using 48 × 3 from this sheet (Set A, problem 4). Each method below reaches the same answer, 144, by a different route; pick the one that makes the most sense to you.
Helps with bigger numbers: split them by place value and multiply the parts.
Step 1Split each number by place value: 48 = 40 + 8; 3 stays as 3.
Step 2Multiply to fill each box.
Step 3Add the boxes: 120 + 24 = 144.
Step 4So 48 × 3 = 144.
Helps you see every piece of a long multiplication before adding them up.
Step 1Split 48 into 40 + 8 and 3 into 3.
Step 2Multiply each part of 3 by each part of 48, starting with the ones.
Step 3Add the partial products: 24 + 120 = 144.
Step 4So 48 × 3 = 144.
Helps you catch place-value slips: round, estimate, then check that the exact answer is close.
Step 1Round each number to its first digit: 48 rounds to 50; 3 stays 3.
Step 2Estimate: 50 × 3 = 150.
Step 3Now work it out exactly: 48 × 3 = 144.
Step 4Compare: 144 is 6 away from the estimate of 150. An answer with a different number of digits from the estimate usually means a place-value slip.
There are 24 multiplication problems here — one page to work, one page of answers to check against — and Sets B and C repeat the layout with different numbers. The blank moves between positions from problem to problem, so no single procedure clears the page and the numbers run as high as 656. Problems 9 and 17, for instance, are "___ × 4 = 132" and "___ × 1 = 61". Common Core 4.NBT.5 is the slot this page fills.
Grade 4 multiplication means two- and three-digit by one-digit products and two-digit by two-digit multiplication. Specifically, the problems practice two-digit by one-digit multiplication. To finish it, a student has to reason backwards from a result to a missing part. 22 different answers appear across the 24 problems, so a student cannot copy one result down the page.
Each of the 24 problems has a blank, and the blank is not always at the end: problem 9, "___ × 4 = 132" puts it where the student has to reason backwards. An unknown factor is division in disguise, so this format is where multiplication and division fact families are built.
All three sets are produced by the site's deterministic generator from a fixed seed, so they are the same every time the site is built and the answer keys are exact. Where Set A's problem 13 is "29 × ___ = 174", Set B's is "23 × ___ = 23".
Work the 24 problems straight through, then check against the key together rather than handing it back marked; asking a grade 4 student to find their own multiplication error teaches more than seeing it circled. Keep the key face down until all 24 problems are finished, then go through the misses together rather than only totaling the score.
One mistake to watch for
A missing factor is found by subtracting: 6 × ___ = 42 is answered 36 instead of 7. On this grade 4 missing number, problem 21 ("91 × ___ = 455") is the kind of item where it shows.
The equals sign is read as an instruction to compute something with the two visible numbers.
Read the equation as a question — "six times what is forty-two" — and connect it to the division fact it is.
The same skill in the other formats available at this grade.
The same format one grade down and one grade up — the easier sheet is often the faster fix when this one is not landing.
