Max Maths, Year 6, Learn together, Multiplying and dividing by multiples of 10 (1)

In a mathematics lesson for Year 6 students, the focus is on multiplying and dividing by multiples of 10. The lesson aims to develop mental maths skills by breaking down larger calculations into simpler steps. One example used to demonstrate this concept involves a classroom scenario: Jade's class has 30 learners, and each learner possesses 20 cents. To find out the total amount of money they have collectively, the calculation is simplified by first multiplying the number of learners (3) by the value each learner has (2), and then multiplying the result by 100. This method reveals that the class has 600 cents in total, which is equivalent to $6.

The lesson continues with further exercises to practice mental multiplication involving larger numbers. Students are encouraged to find 24 multiplied by 200 by initially multiplying 24 by 2, resulting in 48, and then multiplying this answer by 100 to reach the final answer of 4,800. Another example challenges students to multiply 3,000 by 1,200. This is approached by first multiplying 3 by 12, which equals 36, and then multiplying 1,000 by 100. Combining these results, the students learn that 3,000 times 1,200 equals 36 multiplied by 10,000, leading to a final answer of 3,600,000. These exercises help students understand the process of breaking down complex multiplication into more manageable calculations, enhancing their numerical fluency and confidence.
