About this booklet
This booklet was made by Lia's dad, with the help of AI, to help Lia with the Year 2 Place Value unit.
It follows the order of small steps 9–11 of the White Rose Maths Year 2 Place Value unit (Autumn Block 1): 10s on the number line, 10s and 1s on the number line, and estimating numbers on a number line.
Why the focus on halfway?
Young children often give small numbers more room than they need. On a line from 0 to 100, they may put 10 near the middle. This is not strange. It is a normal part of growing up with numbers, and it changes with practice.
The quickest fix is two questions: “Where is halfway?” and “Is it more or less than halfway?” Then check from a number you know, like 0, 50 or 100. A good estimate is close. It does not have to be exact.

| Order | Pages | Topic |
|---|---|---|
| Part 1 | 10s on the line | 10s on a number line — Count in 10s from 0 to 100. Fill in the 10s and read the arrows. |
| Part 2 | 10s and 1s | 10s and 1s — 47 is between 40 and 50. Start at the nearest 10, not at 0. |
| Part 3 | What is each step worth? | Each step — Count the intervals between two numbers. A step can be 2, 5 or 10. |
| Part 4 | Estimate the arrow | Estimate — Find halfway, then say about where the arrow is. |
| Part 5 | Mark the number | Mark the number — Draw an arrow where a number goes. Small numbers go close to 0. |
| Part 6 | Think about it | Think about it — Is the friend right? Tell a grown-up why. |

Good questions to ask
- “What is each interval worth?”
- “Where is halfway?”
- “Is it closer to 0 or to 100?”
- “Which two 10s is it between?”
- “Is your estimate sensible?”
- “Explain how you know.”
Answers are at the end of the workbook. For estimates, any number in the range shown is a good answer. Please note: this is home practice, not official school or White Rose material. If something is taught differently in class, please follow the teacher's method.
How to help at home
- Make a floor line.
Put masking tape on the floor. Write 0 at one end and 100 at the other. Walk it, jump on it, count along it.
- Play “Stand on the number”.
Call a number. Your child stands where it goes and says why: “It is a bit less than halfway.”
- Read the ends first.
Before any number line, ask: “What number does it start at? What number does it end at?”
- Spot scales at home.
Rulers, kitchen scales, jugs, thermometers and the fuel gauge in the car are all number lines.
- Close is good.
Praise a close estimate and the steps used to find it. Do not ask for the exact number.
- Stop while it's fun.
Short and happy is better than long. One Part a day is enough.
The pictures we use
These are the same kinds of number lines used in class. Your child will see them at school too.
