Line plots with fourths worksheets

A line plot marked in fourths is the first one where the ruler itself takes reading. These free printable worksheets put measurements on a scale of quarter inches and ask how many, how many more, and how many were longer.

What's on this sheet

Every question answers with a count or a spot on the ruler, so the fractions are positions to read rather than sums to work. That keeps the page on the skill it is for: finding 1½ on a ruler that also shows 1¼ and 1¾, and knowing which stacks are to the right of it.

Why this sheet works

“Longer than” is the question that catches people, because it asks for every stack to the right and none of the one that was named. Empty positions are part of the picture as well. A length nobody measured is a fact about the data, and it still counts as a place on the ruler.

How this one works

Height of the bean plants (inches)

along the bottom:inches
each mark:one plant
1 inches:3 plants
1¼ inches:2 plants
1½ inches:3 plants
1¾ inches:3 plants
2 inches:2 plants
2¼ inches:2 plants
2¾ inches:4 plants
3 inches:3 plants
1 inches:3 plants
1¼ inches:2 plants
1½ inches:3 plants
1¾ inches:3 plants
2 inches:2 plants
2¼ inches:2 plants
2¾ inches:4 plants
3 inches:3 plants
22
  1. A line plot is not bars to read off a scale — each mark is one plant. So the number ALONG the bottom and the number of marks ABOVE it are two different quantities, and the question wants one of them.
  2. Counting the stacks: 3 at 1, 2 at 1¼, 3 at 1½, 3 at 1¾, 2 at 2, 2 at 2¼, 4 at 2¾, 3 at 3.
  3. 3 + 2 + 3 + 3 + 2 + 2 + 4 + 3 = 22 — so the answer is 22.
