Decimal Tenths on a Number Line - Worksheet | Maths Year 4 - Free Printable

I'll solve this worksheet step by step, explaining how to read decimal tenths on a number line.

First, let's understand the structure:

- Each number line goes from 0 to 1
- There are 10 equal segments between 0 and 1, so each segment represents 0.1 (one-tenth)
- The tick marks represent: 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0

Part 1: What decimal number is identified by the arrow?

Let me examine each part:

For (a):
- The arrow points to the 4th tick mark after 0
- So this represents 0.4

For (b):
- The arrow points to the 8th tick mark after 0
- So this represents 0.8

For (c):
- The arrow points to the 9th tick mark after 0
- So this represents 0.9

For (d):
- The arrow points to the 2nd tick mark after 0
- So this represents 0.2

Part 2: Using an arrow, identify the following decimals on the number line.

This part asks students to draw arrows, but since I can't draw on the image, I'll describe where the arrows should be placed:

For (a) 0.5:
- Place the arrow at the 5th tick mark after 0 (exactly halfway between 0 and 1)

For (b) 0.8:
- Place the arrow at the 8th tick mark after 0

For (c) 0.1:
- Place the arrow at the 1st tick mark after 0

For (d) 0.6:
- Place the arrow at the 6th tick mark after 0

Final Answers:

Part 1:
(a) 0.4
(b) 0.8
(c) 0.9
(d) 0.2

Part 2:
Students need to draw arrows at:
(a) 5th tick mark for 0.5
(b) 8th tick mark for 0.8
(c) 1st tick mark for 0.1
(d) 6th tick mark for 0.6

The key concept here is understanding that when a number line from 0 to 1 is divided into 10 equal parts, each part represents one-tenth (0.1), and we count the segments from 0 to find the decimal value.
