Multiplication and Division - Divide by 1 - Presentation

The presentation focuses on the concept of division, specifically dividing by 1, and is designed to help students understand the effects of this operation on numbers. It begins by encouraging students to explore what happens when a number is divided by 1 or by itself, prompting discussion and comparison of different calculations. The lesson includes a series of activities where students use counters and their hands to visually demonstrate division by 1, such as sharing 3 counters between 3 hands, and then between just 1 hand, to see the difference in outcomes. This hands-on approach helps to solidify the understanding that dividing by 1 leaves the number unchanged, while dividing a number by itself results in 1.

Subsequent activities involve choosing the correct bar model for a given word problem, such as determining how many friends receive £6 if Malachi gives away £6 at a time. This leads to the understanding that only one friend would receive the full amount. Further exercises require students to draw bar models to represent division scenarios, such as sharing 4 marbles between 4 friends and determining how many children can have 9 cookies if there are 9 cookies available. The presentation also challenges students with reasoning questions where they compare division expressions using symbols, and they are tasked with correcting a statement that mistakenly suggests division is commutative. Independent work reinforces these concepts through comparison problems, bar model representations, and matching questions to the correct models, fostering a deeper comprehension of the division by 1.
