Lesson Note: JSS 1 Mathematics, Week 1
Topic: Whole Numbers (Counting and Writing in Millions and Billions)
- Behavioural objectives
- By the end of the lesson, students should be able to: (1) count and write numbers up to one billion in figures and in words; (2) identify the place value of each digit in a multi-digit whole number; (3) compare two whole numbers and state which is greater using <, =, >.
- Instructional materials
- Place-value chart (printed A3), number cards showing 0–9, the board, chalk / marker, and the recommended NERDC JSS 1 Mathematics textbook (chapter 1).
- Entry behaviour
- Students can read and write whole numbers up to one thousand from primary school. The teacher confirms this with two quick oral questions before proceeding.
- Presentation (4 steps)
- Introduce the place-value chart on the board: ones, tens, hundreds, thousands, ten-thousands, hundred-thousands, millions, ten-millions, hundred-millions, billions.
- Work an example together: write 23,408,716 on the board and read it out digit by digit using the chart. Have two students come up and place number-cards in the correct columns for a different number.
- Class activity: in pairs, students write five large numbers from a word list (e.g. "twelve million, four hundred thousand, seven hundred and twelve") into the place-value chart in their exercise books.
- Comparison drill: the teacher writes pairs of numbers on the board and students call out which is greater, justifying using place value.
- Evaluation
- Five quick board questions answered in exercise books: write the place value of the underlined digit, write the number in words, write the number in figures, and compare two numbers using < or >.
- Assignment
- Exercises 1a–1d from the recommended NERDC JSS 1 Mathematics textbook (chapter 1, page 6). Marked at the start of next lesson.
