Multiplication and Division (1) - Divide by 100 - Presentation

In the educational resource focused on multiplication and division, Lesson 12 (R) delves into the concept of dividing by 100. The session begins with a review of dividing by 10, prompting students to discuss the steps involved in this process and to predict the method for dividing by 100 based on their understanding. The lesson is structured to strengthen students' fluency and reasoning skills through a series of engaging activities. For example, students are encouraged to use their knowledge of place value to explain the relationship between multiplying and dividing by 100. They are asked to consider how shifting the digits in a number affects its value when multiplied or divided by 100, thereby reinforcing their understanding of the decimal system.

In one of the activities, students are presented with a practical scenario involving the division of £1 into 100 parts, illustrating that it is indeed possible as £1 is equivalent to 100 pence, with each person receiving 1 pence. Furthermore, the lesson includes matching exercises where students pair calculations with the correct answers, such as 7,300 ÷ 10 and 7,300 ÷ 100, and use comparison symbols to relate different division statements. Through these activities, students gain a deeper understanding of the mathematical operations and apply their skills to solve problems. The lesson culminates with reasoning tasks where students deduce the starting number from given division results and complete calculations using digit cards, thereby fostering critical thinking and a solid grasp of the concepts of division by 100.
