Numbers to 100

Overview

This lesson is Lesson 7 of 9 in the unit "Counting Adventures Ahead." Students will develop their number recognition and writing skills by reading and writing numbers up to 100. A practical and interactive scavenger hunt will consolidate learning, promoting engagement and real-world application.

Duration: 45 minutes
Class size: 25 students
Age group: Year 1 (ages 5-6)
Curriculum link: National Curriculum for England - Mathematics

National Curriculum Alignment

Subject content (Year 1 - Number - Number and Place Value)

Count to and across 100, forwards and backwards, beginning with 0 or 1, or from any given number.
Read and write numbers from 1 to 20 in numerals and words. (Extend to 100 this lesson)
Recognise the place value of each digit in a two-digit number (tens, ones). (introduction in this unit)

Key Learning Objectives

By the end of this lesson, pupils will be able to:

LO1: Read aloud numbers from 1 to 100 accurately as numerals.
LO2: Write numerals correctly up to 100.
LO3: Identify and record numbers found in their environment around the classroom.

Resources Needed

Number cards from 1 to 100 (laminated) hidden throughout the classroom
Paper and pencils / whiteboards and markers for each pupil
Chart showing numbers 1–100 displayed prominently
Large number line (optional for visual reference)
Stickers or stamps (optional for rewards)

Lesson Structure

1. Introduction (10 minutes)

Engage: Begin with a quick number chant, counting aloud together from 1 to 30, then 70 to 100 to excite curiosity about larger numbers. Use a colourful number line for visual support.
Review: Recap the previous lesson’s work on counting to 50 and the concept of tens and ones.
Explain: Today, pupils will read numbers to 100 and write them down during a scavenger hunt around the classroom. Emphasise the importance of recognising numbers in daily life.

2. Guided Practice (10 minutes)

Display several number cards from 1 to 100 around the classroom (start with easier numbers below 50 and increase difficulty).
As a class, read numbers aloud together. Model how to write a two-digit number on the board, emphasising the tens and ones.
Invite a few students to come up and write numbers you call out (e.g., 24, 57, 88).

3. Main Activity: Number Scavenger Hunt (15 minutes)

Explain the scavenger hunt: pupils will find number cards hidden around the classroom (numbers 1 to 100) and write each number found on their worksheet or whiteboard.
Pupils work independently or in pairs to find and record as many numbers as possible during the allotted time. Encourage neat writing.
To differentiate: support lower-ability pupils by giving them a specific range (e.g., 1-30), whilst challenge higher-ability pupils to find higher numbers (e.g., 70-100).

4. Plenary and Assessment (10 minutes)

Gather pupils back on the carpet.
Invite volunteers to share some of the numbers they found and written, asking them to read the number aloud and describe its digits (e.g., "57 has 5 tens and 7 ones").
Use mini whiteboards for rapid-fire number dictation (say a number, pupils write it down immediately).
Quick formative assessment: Check the worksheets for correct numeral formation and understanding. Provide immediate feedback where necessary.

Differentiation

Support: Provide number lines and digit cards with visual cues for struggling pupils. Pair them with a peer helper during the scavenger hunt.
Challenge: Ask more confident pupils to write numbers in words for additional stretch (e.g., write "seventy-three" next to "73").
Use verbal encouragement and stickers to reward effort and accuracy.

Extension Ideas

Create a simple number puzzle using the numbers found during the hunt (e.g., putting numbers in ascending order from their findings).
Introduce matching games where pupils match numeral cards to number words (for reinforcement beyond this lesson).

Assessment & Reporting

Monitor participation and engagement during the scavenger hunt.
Mark pupils’ recorded numbers for correct recognition and writing.
Note pupils who struggle with number formation or reading for targeted future support.
Use observations and mini whiteboard responses to inform next lesson planning.

Reflection for Teachers

After delivering the lesson, reflect on:

Were pupils engaged and motivated during the scavenger hunt?
Did the activity support understanding of numbers beyond 20?
Which pupils may need further intervention on numeral recognition or formation?
Could using different environments (outside the classroom) enrich the experience further?

This lesson effectively links the statutory requirements of the National Curriculum with a hands-on, memorable activity, aiming to build foundational number skills in a playful, immersive context.
