B6 Mathematics · Term 1 Week 3: Counting, Representation, Cardinality & Ordinality

Lesson notes

Learning Objectives

Indicator: B6.1.1.1.4 - Compare and order whole numbers up to 100,000 and represent the comparison using “>, <, or =”

By the end of the lesson, learners can:

Compare two whole numbers up to 100,000 by examining the place value of each digit, starting from the highest place value.
Use the symbols “>”, “<” and “=” correctly to represent the relationship between two numbers up to 100,000.
Use the words “greater than”, “less than” and “equal to” correctly when comparing numbers verbally.
Arrange a set of up to five whole numbers up to 100,000 in ascending order (smallest to largest) and descending order (largest to smallest).
Identify numbers that are 10,000 more or 10,000 less than a given six-digit number up to 100,000.

Exemplars (from the NaCCA curriculum)

E.g. 1 Learners identify numbers which are 10,000 more or 10,000 less than a given six-digit number.
E.g. 123,400 is 10,000 less than133,400 Learners use words such as: "equal to" "greater than" "less than" and later use symbols such as "<", "=", ">" to compare numbers up to 10,000 taking into consideration the place value of each digit in the given number. E.g. 100200 = 100200, 2746794 > 2646796
E.g. 2 Learners work together in their groups to order a given set of numbers in ascending or descending order verbally and in writing. E.g. For instance; 140230, 17025,75 267389, 287368,
E.g. 3 Give two numbers between 10,000 and 100,000 to each group and encourage learners to say as many things as possible about the two numbers. For instance 234675 and 253874; 234675 is less than (smaller than) than 253874 or 253874 is bigger than (greater than) 234675, or 234675 is almost 20000 less than 253874 etc.
