Marks in halves and fourths
12 1/2 inches It passes 2 and ends at the middle mark. That is 2 and a half inches.
23 1/2 inches It passes 3 and ends at the half mark, so it is 3 and a half inches.
31 3/4 inches Each inch is cut in 4 parts. The dot is 3 fourths past 1: 1 and 3 fourths.
4B 2 1/4 is one fourth past 2. A is at 1 3/4 and C is at 2 1/2.
54 Count the X's in the 1 1/2 in row. There are 4.
610 2 + 4 + 3 + 1 = 10.
72 1/2 in The 2 1/2 in row has only 1 X.
84 The 2 in row has 3 and the 2 1/2 in row has 1. 3 + 1 = 4.
91 1/2 inches The longest is 2 1/2 in and the shortest is 1 in. From 1 to 2 1/2 is 1 and a half inches.
10True 2 1/2 is the same as 2 2/4, and 2 2/4 is more than 2 1/4.
11False 1 1/2 is 1 2/4. That is one fourth longer than 1 1/4.
