They imagine the future they want but spend little time preparing for the responsibilities that future will demand. This...

JSS1 FIRST TERM E-NOTE

JSS1 E-Note Series — Edwin Ogie Library

Complete JSS1 lesson pack: topic notes + 4 worked examples each + 20-question CBT (15 minutes) with corrections.

1. Number & Place Value

Place value is the value a digit holds depending on its position in a number. JSS1 students should read, write and compare numbers up to 100,000 and understand place names (units, tens, hundreds, thousands).

4 examples — tap to view
  1. Example 1: Value of 6 in 46,372 =
    6,000 (six thousand)
  2. Example 2: Write 7,208 in words.
    Seven thousand, two hundred eight.
  3. Example 3: Which is larger: 23,465 or 23,456?
    23,465 — compare left to right; tens place decides.
  4. Example 4: Round 12,345 to the nearest ten.
    12,350

2. Addition & Subtraction (Whole numbers)

Methods: column addition/subtraction, mental strategies, checking with inverse operations.

4 examples — tap to view
  1. Example 1: 3,456 + 2,789 =
    6,245
  2. Example 2: 10,000 − 2,347 =
    7,653
  3. Example 3: Use inverse to check 4,321 + ? = 7,000 → ? = 2,679
    Check: 4,321 + 2,679 = 7,000
  4. Example 4: Subtract with borrowing: 5,000 − 1,289 =
    3,711

3. Multiplication & Division (Basics)

Times tables, long multiplication, short division and division with remainder.

    1,842

4. Fractions (intro)

Types (proper, improper, mixed), equivalent fractions, addition/subtraction with common denominators, simple multiplication/division.

    20 and 30
  3. Example 3: If 3/x = 6/12 → x = ?
    x = 6
  4. Example 4: A map scale 1:100 means 1cm = 100cm → 3cm =
