Multiplication and division - Divide two digits by one digit 1 - Presentation

In a series of engaging maths lessons, students are introduced to the concept of dividing two-digit numbers by one-digit numbers. The lessons utilise a variety of visual aids, such as place value counters and grids, to help children understand the division process. For example, Leanna demonstrates how to divide 84 by 2 by partitioning the number using place value counters and forming two equal groups. This hands-on approach is extended to other division problems, such as 84 ÷ 4 and 66 ÷ 3, where students use the same method to calculate the quotient. The lessons are structured to encourage discussion and reasoning, prompting students to think about the relationship between division and multiplication, and how to represent numbers effectively for division.

As the lessons progress, students are presented with various scenarios and strategies to solve division problems. Esin, for instance, uses a place value grid and a part-whole model to divide 66 by 3, illustrating a different technique that reinforces understanding of the division process. The activities are designed to cater to different learning styles, allowing students to explore division through visual, tactile, and conceptual means. Reasoning tasks challenge students to evaluate the correctness of given answers, such as determining whether Zach's solution to 48 ÷ 4 is accurate and explaining their reasoning. These exercises not only test the students' division skills but also enhance their critical thinking and ability to articulate mathematical concepts.
