Decimal - Multiply by 10, 100 and 1,000 - Planning

In a Year 6 maths lesson, students delve into the world of decimals, specifically learning how to multiply decimal numbers by 10, 100, and 1,000. The lesson utilises a variety of resources, including blank place value charts and place value counters, to help visualise the multiplication process. The key vocabulary introduced includes terms such as 'decimals', 'place value', 'tenths', 'hundredths', 'thousandths', and 'multiply'. The class begins with a review of previous knowledge and then moves on to an activity where a child identifies a number on the place value chart. Through discussion, students explore the effects of multiplication on the size of a number and the significance of shifting digits to the left on the chart to represent multiplication by powers of ten. They also learn the importance of using zero as a placeholder to maintain the correct value of the number.

Subsequent activities involve hands-on practice with place value charts and counters, where students multiply numbers such as 1.34 by 10, 100, and 1,000, and record their findings. They also tackle problems with missing stages, using their understanding of place value to fill in the gaps. The lesson encourages partner discussions on how to adapt these skills to multiply by multiples of 10 and 100, such as 20 or 200. Group work and independent activities further reinforce concepts, with differentiated worksheets catering to various learning levels. Students reflect on their learning, discussing what they found challenging and the strategies that aided their understanding. The lesson aims to dispel common misconceptions, such as the movement of the decimal point, and to ensure students can confidently apply their skills to multiply by multiples of 10, 100, and 1,000.
