Place value - Represent numbers to 10,000 - Presentation

In a comprehensive lesson on place value, students are tasked with representing numbers up to 10,000, building upon their previous knowledge of numbers up to 1,000. The lesson begins with a discussion prompt, asking students to recall what they remember about representing smaller numbers. Following this, they engage in a series of activities designed to deepen their understanding of place value. The first activity challenges students to consider the importance of order when building numbers and to write down the numbers represented by various combinations of thousands, hundreds, tens, and ones. This activity not only reinforces the concept of place value but also encourages students to recognize patterns and relationships between different numerical representations.

Further into the lesson, students are presented with a choice between using base 10 blocks or counters to represent given numbers, prompting them to consider their preferences and the reasons behind them. This hands-on approach facilitates a tactile understanding of numerical value. Additionally, reasoning tasks are incorporated to enhance critical thinking, such as determining the missing amounts in a partially covered base 10 representation and exploring multiple ways to make up a specific number using base 10 components. Students are also asked to analyze representations made by others, explaining how they know which child has accurately represented a given number. The lesson concludes with independent work, where students must identify numbers from pictorial images and deduce which counters may have been lost from a representation, further solidifying their place value skills.
