Behavioral Objectives:

By the end of the lesson, pupils should be able to:

  1. Identify numbers from 1-130.
  2. Read and write numbers 1-130 in numerals.
  3. Compare numbers from 1 to 130 using “more than,” “less than,” and “equal to.”
  4. Count forward in ones from any number between 1-100.

Keywords:

Numbers, Counting, More than, Less than, Equal to, Order, Shapes, Numerals, Counting by 2s, Counting by 10s

Set Induction:

  • Activity: Begin the lesson by asking pupils to count from 1 to 20 aloud. Then, ask them to count backwards from 20 to 1. Praise them for their participation.
  • Rationale: This introduces them to the importance of counting and sets the stage for counting numbers beyond 100.

Entry Behavior:

  • Pupils should be able to count numbers from 1 to 100.

Learning Resources and Materials:

  • Flashcards with numbers 1-130
  • Number chart (1-130)
  • Whiteboard and markers
  • Playing cards with numbers
  • Counters or objects for counting
  • Dictation sheets for writing numbers

Building Background/Connection to Prior Knowledge:

  • Pupils should already be familiar with numbers 1-100 and counting by ones.
  • They have learned about greater than, less than, and equal to in previous lessons.

Embedded Core Skills:

  • Communication Skills: Pupils will discuss numbers in groups and practice dictation.
  • Critical Thinking Skills: Pupils will compare and order numbers.
  • Problem-solving Skills: Pupils will apply counting skills in real-life situations.

Learning Materials:

  • Flashcards with numbers 1-130
  • Dictation practice sheets
  • Counters for hands-on counting

Reference Books:

  • Lagos State Scheme of Work for Primary 1 Mathematics
  • Lagos State Curriculum for Mathematics

Instructional Materials:

  • Flashcards with numbers from 1-130
  • A number chart with numbers from 1 to 130
  • Whiteboard and markers
  • Playing cards with numbers for hands-on learning

Content:

  1. Definition of Whole Numbers 1-130:
    • Whole numbers are numbers that do not have fractions or decimals. They are used for counting and measuring.
    • Numbers 1-130 represent a set of whole numbers that can be counted from 1 to 130.
  2. Explanation of Numbers 121-130:
    • Numbers from 121 to 130 are an extension of the basic counting numbers we use in everyday life.
    • The number after 120 is 121, followed by 122, 123, 124, and so on until 130.
  3. Comparing Numbers Using More Than, Less Than, Equal To:
    • “More than” means a number is larger.
    • “Less than” means a number is smaller.
    • “Equal to” means both numbers are the same.
  4. Counting in Ones, Twos, and Tens:
    • Counting forward in ones means increasing the number by one each time.
    • Counting in twos means skipping one number each time (e.g., 2, 4, 6, 8…).
    • Counting in tens means skipping ten numbers each time (e.g., 10, 20, 30…).

Examples:

  1. 121 comes after 120.
  2. 125 is more than 120 but less than 130.
  3. 130 is the last number in this sequence.
  4. Counting by 2s: 2, 4, 6, 8, 10…
  5. Counting by 10s: 10, 20, 30, 40, 50…
