Multiplication and division - Divide by 8 - Presentation

Lesson 18 of a mathematics teaching series introduces Year 3 students to the concept of dividing by 8 through a series of practical and visual activities. The lesson encourages students to practise counting in multiples of 8 and to recognise patterns within the sequence. For example, students are asked to continue the sequence 8, 16, 24, and so on, to identify the next four numbers. The lesson then moves on to real-life applications of division by 8, such as dividing 32 children into equal teams for a relay race, sharing 72 flowers into vases, or determining the number of packs of pens needed for a class.

Each activity is designed to reinforce the division process through grouping and sharing, with the use of concrete or pictorial representations like counters or multi-link cubes to aid understanding. Students are prompted to fill in the blanks for the number of teams or items in each group after performing the division. Additionally, the lesson includes activities that challenge students to complete missing numbers in division and multiplication equations, enhancing their fluency with the concept. The lesson concludes with reasoning exercises where students observe patterns in their answers, identify numbers divisible by 8, and apply their knowledge to predict outcomes in division problems.
