Place value - Tens and ones within 20 - Presentation

In a presentation designed to teach young learners about place value, specifically the concept of tens and ones within the number range of 20, students are encouraged to explore and understand the basic building blocks of our number system. The lesson begins with a question that prompts students to define tens and ones and provide examples of numbers up to 20 that illustrate these components. Through a series of interactive slides, the presentation guides students to discuss and recognise the difference in value between a ten and a one, and why a ten is greater than a one.

The presentation includes a variety of activities where students use ten frames and counters to represent numbers such as 14 and 19, reinforcing the visual aspect of tens and ones. Students are asked to fill in the ten frames and then complete sentences to show their understanding of how many tens and ones are in a given number. Independent work further challenges students to represent numbers using ten frames and to express numbers as a combination of tens and ones. The lesson also encourages discussion around the significance of the 'teen' suffix in numbers, the concept of swapping tens for ones, and the efficiency of counting by tens rather than starting from zero every time. This interactive approach helps students to visualise and articulate their understanding of place value within the context of the numbers they encounter every day.
