Counting · Number words · Facts within 20 · goes with “Lia's Maths Book – Year 1 Review”
This guide helps Lia practise the Year 1 number work at home. It explains each part in easy English, with things to say, questions to ask, and games to play.
The most important word in this guide is again. Counting and number facts become easy only with short, happy practice, many times.
Made by Lia's dad with the help of AI. It follows the Year 1 Number programme in the National Curriculum for England (place value, and addition and subtraction), which Lia's school follows. It is home practice, not official school material.
What Year 2 expects from Year 1
Five things from Year 1. This guide has one topic for each.
| Year 1 goal (National Curriculum) | What it means | Topic |
|---|---|---|
| count forwards and backwards to and across 100 | Say numbers in order, up and down, from any number, and past 100 (… 99, 100, 101 …). | 1 |
| read and write numbers to 100 in numerals | Read 47 and write 47 when someone says “forty-seven”. Know tens and ones. | 2 |
| count in 2s, 5s and 10s | 2, 4, 6, 8 … / 5, 10, 15 … / 10, 20, 30 … and back again. | 3 |
| write numbers 1 to 20 in words | Read and spell one, two, three … twenty. | 4 |
| addition and subtraction facts within 20 | Know facts like 8 + 7 = 15 and 15 − 7 = 8 quickly. | 5 |

In Year 2, every lesson uses these skills. For example, adding 38 + 5 needs counting across 40, and bonds to 10. If these skills are quick and easy, Lia can think about the new idea, not the counting.

Lia probably knows the maths. Now she needs it in English.
Children in Korea learn numbers to 100 and adding within 20 in Grade 1. So the maths is probably not new for Lia. What may be new is doing it in English: counting out loud quickly in English, reading and spelling English number words, and understanding English questions.
So in this guide, speaking and listening are as important as writing. Count out loud together every day.
The repeat plan (15 minutes a day)
| Minutes | What to do | Where |
|---|---|---|
| 3 | Count out loud. One kind each day: forwards across 100, backwards, 2s, 5s, 10s. | Topic 1 and 3 games, or the Counting machine on the web page |
| 8 | One Daily Practice page. Lia works. You sit with her and ask questions. | Workbook: Daily Practice 1–10 |
| 2 | Check together. Count the score. Colour the stars on the tracker. | Answers: at the back of the workbook. Tracker: How to use this book |
| 2 | One quick game from this guide or the web page. | “Games” in each topic |
