What this worksheet covers
Set A of this grade 7 missing number sheet holds 24 decimals problems on one printable page, with the answer key on the page behind it. Eighteen of the 24 problems involve a negative quantity and some operands are decimals rather than whole numbers. Two problems from the middle of the page — "-0.1 × ___ = -0.6" and "-9.5 × ___ = -47.5" — show the range. It is written against Common Core 7.NS.2 — The Number System, grade 7.
Skills practised
The grade 7 decimals sequence covers adding, subtracting, multiplying and dividing signed decimals, and repeating decimals; this page sits inside it. Specifically, the problems practise multiplying and dividing signed decimals and missing terms with signed decimals. Working the page asks a student to keep the decimal points aligned, track direction as well as magnitude, and reason backwards from a result to a missing part. Seventeen different answers appear across the 24 problems, so a student cannot copy one result down the page.
About the missing number format
The 24 problems here move the unknown around, so a student solves for a missing part as often as for a result; problem 9, "-0.1 × ___ = -0.6" is one of them. A missing addend or factor with decimals asks the student to undo an operation, which exposes place-value gaps that forward computation hides.
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 13 is "-7.0 × ___ = -49.0", Set B's is "-9.2 × ___ = -18.4".
How to use this worksheet
Expect twenty minutes or so of real attention for 24 problems. At grade 7, decimals rewards care over speed — a rushed missing number gets the arithmetic right and the signs or units wrong. Mark the 24 problems the same day using the key — an error caught immediately is a correction, and one caught next week is a habit.
One mistake to watch for
The decimal point in a product is placed by lining up the points. On this grade 7 missing number, problem 17 ("-9.5 × ___ = -47.5") is the kind of item where it shows.
The addition rule is being reused for multiplication, where it does not apply.
Count decimal places in both factors and give the product that many; estimate first so a wildly wrong placement stands out.
