Share whole numbers not exceeding 48 into equal groups of 2, 3, 4, 5, or 6 without any remainder.
Show how whole numbers not exceeding 48 can be made by multiplying two other numbers (e.g., 12 = 3 x 4).
Find a missing number when given a multiplication problem (e.g., 3 x ? = 15).
Tell the difference between numbers that divide into another number exactly (factors) and numbers that are products of another number (multiples).
Identify and use division correctly in various everyday situations, such as sharing food, money, or school supplies.
Lesson summary
This lesson introduces Primary 3 learners to the fundamental concept of division, building upon their prior knowledge of multiplication and subtraction. Division is a critical mathematical operation essential for equitable distribution, resource management, and problem-solving in everyday life. Understanding division helps learners perform calculations related to sharing, grouping, and finding how many times one number is contained within another. This topic also introduces related concepts such as factors and multiples, which are foundational for future mathematical learning, including fractions and algebra.
Teacher activity
Demonstrates sharing using concrete objects. For example, "I have 12 bottle tops and I want to share them equally among 3 groups." The teacher physically distributes the bottle tops, one by one, into three designated areas.
Demonstrates grouping: "I have 15 beans. I want to put them into groups of 5. How many groups can I make?" The teacher counts out groups of 5 beans.
Explains how to record this on the board (e.g., 12 รท 3 = 4).
Evaluation guide
Observation: The teacher observes students during group activities (sharing manipulatives, drawing patterns) to gauge their understanding and participation.
Questioning: The teacher asks probing questions throughout the lesson (e.g., "How did you get that answer?", "Can you explain another way?").
Classwork Review: The teacher collects and quickly reviews responses from Guided Practice and selected Independent Practice questions to identify common misconceptions.
Mini Whiteboards/Chalkboard Activity: Students write answers to quick division or factor/multiple questions on individual whiteboards or slates for immediate feedback.
