- 2.2 equal parts make one whole, so each part is 1/___
- 3.2/3 + ___/3 = 1
- 4.1/4 of ___ = 1
- 5.4 equal parts make one whole, so each part is 1/___
- 6.3/4 + ___/4 = 1
- 7.1/4 of ___ = 2
- 8.3 equal parts make one whole, so each part is 1/___

What this worksheet covers
24 fractions problems fill this missing number page; problem 9 asks "2/4 + ___/4 = 1", and the sheet stays at that level throughout. What makes this set particular: several problems use mixed numbers, which have to be handled without dropping the whole-number part and the blank moves between positions from problem to problem, so no single procedure clears the page. Further down, problem 17 asks "1/2 of ___ = 8". The skill maps to Common Core 2.G.3.
Skills practiced
At grade 2, fractions is about naming halves, thirds and fourths of a shape, and half or a quarter of a set, and this sheet takes one slice of that. The skills on the page: half and a quarter of a set, how many equal parts, and parts that make a whole. Working the page asks a student to work in fractional units and give the answer in lowest terms and reason backwards from a result to a missing part. Twelve 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, "2/4 + ___/4 = 1" is one of them. A missing numerator or a missing factor asks the student to think about the fraction relationship in reverse.
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 "1/2 of ___ = 6", Set B's is "1/2 of ___ = 3".
How to use this worksheet
Grade 2 attention runs short, so split these 24 fractions problems over two or three sittings rather than pushing through in one; a number line or counters within reach is a strategy, not a failure. Print Set B of this fractions missing number before writing on Set A; the same skill worked twice a week apart tells you far more than once.
