Line Plots With Eighths
12 Look at the stack over the number 2 and count its dots.
24 Count every dot. A stack counts once for each jar.
3Plot 2 Plot 2 has one dot at 3 and two dots at 5.
42 2 + 2 + 5 + 7 = 16 eighths, and 8 eighths make 1 cup, so 16 eighths make 2 cups.
5False 1 + 3 + 4 + 4 = 12 eighths. That is more than 8 eighths, which is 1 cup.
63/8 12 eighths shared by 4 jars is 3 eighths each.
76/8 The fullest jar holds 7/8 and the emptiest 1/8. 7/8 − 1/8 = 6/8, which is 3/4.
81 and 4/8 cups 1/8 + 4/8 + 7/8 = 12/8, which is 1 whole and 4/8 more.
91-A, 2-B, 3-C Add the tops and keep eighths. 8 eighths make 1 cup.
101/2 1 + 3 + 5 + 7 = 16 eighths. 16 eighths shared by 4 is 4 eighths, which is 1/2.
113/8 The fullest beaker had 7/8 and now has 4/8. 7/8 − 4/8 = 3/8.
