Max Maths, Year 4, Learn together, Multiplication review (3)

In a Year 4 mathematics lesson from Max Maths, students review the concept of multiplication with a focus on the unique properties of multiplying by zero. The lesson begins with a simple yet fundamental question: "What happens when we multiply a number by 0?" To illustrate this concept, the lesson uses relatable examples involving children and counters. Jade has 20 counters, which is represented by the multiplication 2 × 10 = 20. Tya has 10 counters, shown as 1 × 10 = 10. Then there's Han, who has 0 counters, leading to the equation 0 × 10 = 0. This sets the stage for the key learning point that any number multiplied by zero will always result in zero.

Following this introduction, students are encouraged to practice their mental multiplication skills by multiplying various numbers by 10. The exercise includes numbers of increasing complexity, such as 15, 56, 70, 123, 628, and 1,554, to challenge and enhance students' quick calculation abilities. This part of the lesson aims to reinforce their understanding of multiplication by 10 and to solidify the concept that multiplying any number by zero yields zero. The lesson directs students to workbook pages for further practice, ensuring that they have ample opportunity to apply what they've learned in different contexts and solidify their grasp of multiplication principles.
