Max Maths, Year 6, Practice, Multiplying and dividing by multiples of 10

In the "Max Maths" practice exercises for Year 6 students, the focus is on sharpening mental arithmetic skills, specifically multiplying and dividing by multiples of 10. The "Let’s Practise" section challenges students to complete a series of calculations mentally and encourages them to time themselves with a stopwatch to track their speed. The exercises include straightforward multiplications and divisions, such as multiplying 600 by 300 and dividing 500 by 10, as well as more complex calculations like multiplying 1,200 by 50 and dividing 2,400 by 800. The aim is to complete all twelve problems accurately and quickly, with students recording their total score out of 12 and the time taken to complete the task.

Following the mental arithmetic practice, the "Calculate It" section invites students to use a calculator to multiply and divide by multiples of 10. This exercise provides a hands-on approach to understanding the pattern and relationship between the number of zeros in the base numbers and their products or quotients. The instructions guide students through specific calculations, such as multiplying 1,490 by 100 and dividing 3,500 by 70, and then prompt them to observe and record the resulting numbers displayed on the calculator screen. Students are further encouraged to experiment with their own choice of numbers and multiples of 10, to deepen their understanding of the concepts. They are asked to note patterns in the number of zeros, fostering a conceptual grasp of how multiplication and division by 10s affect the placement and number of zeros in an answer. The exercises are linked to workbook pages for additional practice and reinforcement of the concepts learned.
