Place Value – Basic 2 Mathematics Lesson Note (First Term)

Learning Objectives

By the end of this week, pupils should be able to:

• Count and identify numbers from 1-320
• Write numbers 1-320 in numerals and words
• Understand units, tens, and hundreds place values
• Split numbers into place value parts
• Group numbers and objects in 10s
• Identify place values up to 500

Lesson Content

Day 1: Counting to 320

Extending Our Range:

• Count from 1-320
• Focus on numbers 300-320
• Practice reading: 301, 302, 303… 320
• Write these numbers clearly

Day 2-3: Understanding Place Value

What is Place Value? Place value tells us what each digit means in a number.

The Three Places:

• Units (Ones): How many single items
• Tens: How many groups of 10
• Hundreds: How many groups of 100

Examples:

• In 234: 2 hundreds, 3 tens, 4 units
• In 156: 1 hundred, 5 tens, 6 units
• In 89: 8 tens, 9 units (no hundreds)

Day 4: Breaking Down Numbers

Splitting Numbers:

Example 1: 145

• Hundreds: 1 (which means 100)
• Tens: 4 (which means 40)
• Units: 5 (which means 5)
• So: 145 = 100 + 40 + 5

Example 2: 267

• Hundreds: 2 (which means 200)
• Tens: 6 (which means 60)
• Units: 7 (which means 7)
• So: 267 = 200 + 60 + 7

Day 5: Grouping in 10s

Making Bundles of 10:

• 10 units = 1 ten
• 10 tens = 1 hundred
• Use objects like straws, sticks, or blocks
• Bundle 10 items together with rubber bands

Skip Counting by 10s: When we have bundles of 10, we can count: 10, 20, 30, 40…

Examples in Class

Place Value Examples:

Number: 178

• H T U
• 1 7 8
• 1 hundred + 7 tens + 8 units
• 100 + 70 + 8 = 178

Grouping Example:

“We have 23 pencils. Let’s make bundles of 10:

• 2 bundles of 10 = 20 pencils
• 3 single pencils left = 3 pencils
• Total: 2 tens and 3 units = 23″

Real-Life Example:

“In our classroom:

• 2 boxes of crayons (each box has 100 crayons) = 200 crayons
• 3 packs of 10 crayons = 30 crayons
• 5 single crayons = 5 crayons
• Total: 235 crayons”

Exercises

Exercise 1: Place Value Recognition

Write the place value of the underlined digit:

1. 145 = ___ tens
2. 267 = ___ hundreds
3. 893 = ___ units
4. 321 = ___ tens

Exercise 2: Breaking Down Numbers

Split these numbers into hundreds, tens, and units:

1. 156 = ___ + ___ + ___
2. 234 = ___ + ___ + ___
3. 89 = ___ + ___
4. 305 = ___ + ___ + ___

Exercise 3: Building Numbers

What number do these make?

1. 2 hundreds + 4 tens + 7 units = ___
2. 1 hundred + 9 tens + 3 units = ___
3. 3 hundreds + 0 tens + 8 units = ___
4. 0 hundreds + 6 tens + 5 units = ___

Exercise 4: Grouping in 10s

1. How many tens are in 50? ___
2. How many tens are in 80? ___
3. 4 tens = ___ units
4. 7 tens = ___ units

Exercise 5: Real-Life Problems

1. A shop has 3 boxes of 100 sweets, 4 packs of 10 sweets, and 6 single sweets. How many sweets altogether? 
2. Mary collected 267 bottle tops. How many hundreds, tens, and units does she have? 

Exercise 6: Place Value Charts

Fill in the chart:

Fun Activities

• Place Value Game: Use base-10 blocks or bundles of sticks
• Number Building: Create numbers using hundreds, tens, and units cards
• Grouping Race: Who can make the most bundles of 10?

Homework

• Practice identifying place values in numbers around your home
• Group 20-30 small objects into tens at home
• Write 5 three-digit numbers and break them down

Assessment

• Can the child identify place values correctly?
• Do they understand the concept of grouping in 10s?
• Can they break down numbers into hundreds, tens, and units?
• Can they build numbers from place value parts?
• Do they understand that position matters in numbers?
