Answer key · Set C
Fourths on the line plot
12 1/4 inches Each inch is cut in 4 parts. The dot is 1 fourth past 2: 2 and 1 fourth.
23 3/4 inches The dot is 3 fourths past 3: 3 and 3 fourths.
3A 2 3/4 is three fourths past 2. B is at 2 1/2 and C is at 3 1/4.
43 Count the X's in the 1 3/4 in row. There are 3.
54 The 2 in row has 3 and the 2 1/4 in row has 1. 3 + 1 = 4.
66 1 + 2 + 3 = 6 pods are 1 1/4, 1 1/2 or 1 3/4 inches.
71 inch The longest is 2 1/4 in and the shortest is 1 1/4 in. From 1 1/4 to 2 1/4 is 1 inch.
81 3/4 in and 2 in Both the 1 3/4 in row and the 2 in row have 3 X's.
9True 2 inches or longer: 3 + 1 = 4 pods. Shorter than 1 3/4: 1 + 2 = 3 pods. 4 is more than 3.
104, 3, 2, 1 Put them on a line cut in fourths: 1 2/4, 1 3/4, 2 1/4, 2 2/4.
