This comprehensive Multiples and Factors presentation has been created to guide students through what multiples and factors are. It also explores Highest Common Factors (HCF) and Lowest Common Multiples (LCM). In addition, it explores the rules of divisibility and how multiples and factors can be used to solve word problems. The presentation explains these concepts through detailed examples and opportunities for shared practise, through Think-Pair-Shares. While the unit is predominantly aimed at Year 5, this presentation could be used in lower of higher grades for extension or revision.
Express natural numbers as products of their factors, recognise multiples and determine if one number is divisible by another
Create and use algorithms involving a sequence of steps and decisions and digital tools to experiment with factors, multiples and divisibility; identify, interpret and describe emerging patterns
Identify and describe factors and multiples of whole numbers and use them to solve problems
Identify and describe factors and multiples of whole numbers and use them to solve problems
Describe, continue and create patterns with fractions, decimals and whole numbers resulting from addition and subtraction
Follow a mathematical algorithm involving branching and repetition (iteration)
Describes and represents mathematical situations in a variety of ways using mathematical terminology and some conventions
Selects and applies appropriate problem- solving strategies, including the use of digital technologies, in undertaking investigations
Orders, reads and represents integers of any size and describes properties of whole numbers
Gives a valid reason for supporting one possible solution over another
Analyses and creates geometric and number patterns, constructs and completes number sentences, and locates points on the Cartesian plane
Applies an understanding of place value and the role of zero to represent the properties of numbers
