Multiplication and Division - Multiply and divide by 9 - Presentation

Today's lesson is centred around the mathematical operations of multiplication and division, specifically focusing on the number 9. Students are encouraged to count in multiples of 9 to strengthen their understanding of the sequence. The lesson includes a variety of activities designed to reinforce these concepts. For instance, one activity requires students to complete sentences about apples boxed in groups of 9, prompting them to calculate the total number of apples by using multiplication. This exercise not only tests their numerical skills but also their ability to link related mathematical facts, thereby deepening their comprehension of the multiplication table of 9.

Another key component of the lesson involves the construction of fact families, which are sets of related multiplication and division facts. Students are tasked with filling in the blanks to complete these fact families, thereby illustrating the inverse relationship between multiplication and division. For example, if 9 multiplied by 4 equals 36, then 36 divided by 9 equals 4. The lesson also includes reasoning exercises where students must determine the truth of certain statements, such as whether multiplying 6 by 9 yields the same result as multiplying 9 by 3 and then by 2. Through these activities, students are encouraged to use concrete or pictorial representations to aid their understanding and to draw connections between different times tables, thereby enhancing their overall mathematical fluency.
