LESSON 1: WHOLE NUMBERS
In this lesson, we look at whole numbers, which learners studied in Grade 4. Use this lesson for revision. You will see the time allocation is only 2 hours. If learners do not understand the content yet, you may spend more time as needed.
Revise the different notations of numbers. Make sure learners understand notations as it lays the foundation for the language of mathematics. If they are already comfortable with this, it can simplify the introduction of new concepts.
Learners will: • count • order • compare • represent • indicate place value (which is important for calculations later in the term)
Make sure learners have mastered the concepts before they start working with larger numbers in unit 2.
Do you still remember what a whole number is?
Whole numbers do not have fractions or decimals. Whole numbers are always positive and never negative. Remember: 0 is also a whole number.
Learners were introduced to whole numbers in Grades 3 and 4. Make sure they know a whole number is not a fraction. Use different games to reinforce this concept.
Example
Write down different numbers, including fractions and whole numbers. Learners close their eyes and randomly point to a place on the page. They identify the number they chose as a whole number or not.
