Grade 5 learners match decimals to their correct positions on a number line, counting tenths, hundredths, and thousandths ticks. They compute midpoints, identify ticks past benchmark values, and reason about ascending sequence using place value. Fill-in and matching prompts strengthen number line fluency, magnitude comparison, and decimal-to-position mapping aligned with the CCSS 5.NBT.3b standard. Grade 5 students master decimal positioning.

Comparing and Ordering Decimals
Part A: Fill in the Blank
Write the missing word or number on each line.
1. On a number line from 0 to 1 marked every 0.1, the point at the third tick to the right of 0 represents 0.3.
2. On a number line from 2 to 3 marked every 0.05, the point at 2.25 is 5 ticks past 2.
3. Between 0.4 and 0.5 on a number line, the midpoint is 0.45.
4. On a number line from 1 to 2 with marks every 0.1, the point that matches 1.7 is the 7th mark from 1.
5. Between 0.6 and 0.7 on a number line marked in hundredths, the value 0.63 is 3 ticks past 0.6.
6. Mark which decimal is closest to 0.5 from this list: 0.45, 0.55, 0.5, 0.49 — answer 0.5.
7. On a number line marked 0 to 1, what decimal is at the halfway point? 0.5
8. What decimal is plotted at three-fourths of the distance between 0 and 1? 0.75
9. A point on a number line lies between 0.6 and 0.7, exactly halfway. The point is 0.65.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Point A: third tenth past 0
→ 0.3
0.3
Point B: midpoint of 0.2 and 0.4
→ 0.3 plus zero — wait, equals 0.3? No: equals 0.30 padded — actually 0.30 differs
0.3 plus zero — wait, equals 0.3? No: equals 0.30 padded — actually 0.30 differs
Point C: two hundredths past 0.5
→ 0.52
0.52
Point D: halfway between 0.7 and 0.8
→ 0.75
0.75
