Multiplication and Division (1) - Multiply by 10 - Worksheet

The lesson on multiplying by 10 is designed to enhance students' mental multiplication and division skills through the understanding of place value and derived facts. The National Curriculum objective is met through a variety of resources including differentiated worksheets and teaching slides. The key vocabulary for this lesson includes terms such as 'multiplication', 'ten lots of', 'equal', 'commutative law', and 'calculations'. The importance of visualising numbers becoming ten times larger is emphasised, and the phrase 'ten lots of' is integral to the teaching of multiplication by 10. Understanding that the commutative law makes calculations like 10 x 3 and 3 x 10 equivalent is also a crucial learning point.

Students are encouraged to represent multiplication problems with concrete objects or drawings and discuss their methods with peers. They explore the patterns noticed when multiplying by 10 and are prompted to consider if the rule always applies. The activities include matching statements to bar models and identifying the difference in commutative calculations using images. Higher-level tasks involve reasoning and problem-solving, where students might determine which calculations fit within a given range or identify the odd one out among several cases. The worksheets guide students through various scenarios, such as determining the number of passengers on buses or the number of pencils in packets, to reinforce the concept of multiplying by 10.
