Place Value - Numbers to 100,000 - Presentation

The educational resource offers a series of engaging activities designed to enhance students' understanding of place value for numbers up to 100,000. In one activity, a number is presented within a place value grid that segments the digits into tens of thousands, thousands, hundreds, tens, and ones. Students are tasked with writing the number both in numerical form and in words. To deepen their comprehension, they perform simple additions to this number: Tia adds 10, Malachi adds 100, and Rosie adds 1,000. Each resulting number must also be expressed in figures and words, allowing students to observe the changes in the place value grid and understand the effect of each addition on the different place value positions.

Further activities involve reasoning tasks, such as identifying the value of a letter on a number line when given its relation to other values, and exploring various ways to partition a number like 28,850 into thousands, hundreds, tens, and ones. Students are encouraged to think critically and creatively to come up with alternative partitioning methods. Another reasoning task challenges students to identify which numbers a character named Leanna will say when counting forwards and backwards in tens from a given number. This activity helps students to recognise patterns and sequences in numbers. Additionally, the resource prompts discussion on estimation techniques on a number line and the changes in digits when adding 10, 100, or 1,000, encouraging students to articulate their mathematical thinking and reasoning.
