What this worksheet covers
There are 21 fractions problems here — one page to work, one page of answers to check against — and Sets B and C repeat the layout with different numbers. What makes this set particular: several problems use mixed numbers, which have to be handled without dropping the whole-number part and the numbers run as high as 10. Problems 8 and 15, for instance, are "2 × 5/6" and "9 × 2/9". It is written against Common Core 4.NF.4 — Number & Operations—Fractions, grade 4.
Skills practised
Grade 4 fractions means adding and subtracting like denominators, equivalent fractions, and multiplying by a whole number. The skill on the page: multiplying Fractions by Whole Numbers. Working the page asks a student to work in fractional units and give the answer in lowest terms. Twelve different answers appear across the 21 problems, so a student cannot copy one result down the page.
About the timed drill format
The timer box at the top has room for minutes, seconds and a score out of 21; a realistic target for a page like this, where problem 8, "2 × 5/6" is a typical item, is two to three minutes. Equivalent fractions and simple sums recalled quickly are what free a student's attention for the harder operations later.
Set A, Set B and Set C
Set A is the sheet as it was first published on MathSheetLab, 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 "3 × 4/9", Set B's is "3 × 7/9".
How to use this worksheet
Give this timed drill uninterrupted. At grade 4, fractions is where procedure and recall have to run at the same time, and 21 problems done in fragments hide which of the two is the problem. Print Set B of this fractions timed drill before writing on Set A; the same skill worked twice a week apart tells you far more than once.
