Whole Numbers (270-300) And Number Writing Basic 2 Mathematics Lesson Note

Learning Objectives

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

• Count numbers from 1-300 confidently
• Write numbers from 1-300 in numerals
• Write numbers up to 200 in words
• Skip count in 2s, 3s, 5s, and 10s up to 300
• Identify numbers at random
• Read and write numbers in reverse order

Lesson Content

Day 1-2: Mastering 270-300

Focus Numbers: 270-300

• Practice counting from 270 to 300
• Learn to recognize these numbers quickly
• Understand the pattern: 270, 271, 272… 299, 300

Number Formation:

• Practice writing numbers 270-300 clearly
• Pay attention to number shapes and sizes
• Use lined paper for neat writing

Day 3: Writing Numbers in Words

Numbers in Words (1-200):

• One to twenty: one, two, three… twenty
• Twenty-one to ninety-nine: twenty-one, thirty-five, sixty-seven
• One hundred to two hundred: one hundred, one hundred and fifty, two hundred

Examples:

• 45 = forty-five
• 67 = sixty-seven
• 123 = one hundred and twenty-three
• 189 = one hundred and eighty-nine

Day 4: Skip Counting Mastery

Skip Counting in Different Numbers:

In 2s: 2, 4, 6, 8… up to 300 In 3s: 3, 6, 9, 12… up to 300 In 5s: 5, 10, 15, 20, 25… up to 300 In 10s: 10, 20, 30, 40… up to 300

Day 5: Reverse Counting

Counting Backwards:

• Count backwards from 20 to 1
• Count backwards from 50 to 40
• Count backwards from 100 to 90

Random Number Identification:

• Quick recognition of numbers shown on cards
• Finding numbers on a hundred square
• Number games and activities

Examples in Class

Number Writing Example:

In Numerals: 156, 234, 298 In Words:

• 156 = one hundred and fifty-six
• 234 = two hundred and thirty-four
• 298 = two hundred and ninety-eight

Skip Counting Examples:

• By 5s: “5, 10, 15, 20, 25, 30” (helps with telling time later!)
• By 10s: “10, 20, 30… 300” (helps with money!)

Reverse Counting Example:

“Let’s count down like a rocket launch: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, BLAST OFF!”

Exercises

Exercise 1: Number Writing

2. 3, 6, 9, ___, 15, ___, 21
3. 2, 4, 6, 8, ___, 12, ___

Exercise 3: Reverse Counting

Count backwards:

1. 30, 29, 28, ___, ___, 25
2. 100, 99, 98, ___, ___, 95
3. 50, 48, 46, ___, ___, 42

Exercise 4: Random Number Recognition

Circle the biggest number in each group:

1. (145, 154, 141)
2. (267, 276, 627)
3. (198, 189, 291)

Exercise 5: Mixed Practice
