Multiplication and division - Count in 10s - Presentation

The concept of counting in tens is an essential mathematical skill, and a set of teaching slides aims to reinforce this through a series of interactive and engaging activities. The lesson encourages students to think about different scenarios where counting in tens can be applied, such as tallying candles on a birthday cake, fish in a tank, or cupcakes on a tray. Students are prompted to discuss various counting strategies and to observe the efficiency of counting in groups, such as in twos, fives, or tens, compared to counting individually. The lesson also introduces the use of visual aids like a number line and a 100 square to help visualise and practise counting in tens.

As the lesson progresses, students explore the concept of multiplication in the context of counting in tens. They are challenged to identify patterns and relationships between the number of tens and the total value, with exercises that build upon their understanding of one ten equalling ten ones, two tens equalling twenty, and so on. The lesson includes practical activities where students can apply their knowledge, such as colouring in tens on a blank 100 square and counting forwards and backwards in tens with a partner. The discussion points encourage students to consider real-life applications of counting in tens and the tools that can assist them, such as physical counting aids or visual representations like charts and grids.
