Place value - Numbers to 100,000 - Presentation

The educational resource provides a comprehensive series of activities designed to strengthen students' understanding of place value for numbers up to 100,000. In the first activity, a number is presented within a place value grid, delineating the tens of thousands, thousands, hundreds, tens, and ones. Students are tasked with writing the number both in numerical form and in words. To further their grasp, they are asked to calculate and express new numbers after adding 10, 100, or 1,000 to the original number, as demonstrated by characters Tia, Malachi, and Rosie. This exercise not only reinforces their number writing skills but also prompts them to consider how many digits change when different values are added to a base number.

Subsequent activities delve into representing numbers in various formats, such as counters, bar models, number lines, and part-whole models, allowing for a visual and conceptual understanding of numerical value. For instance, the number 65,048 is broken down into its constituent parts, demonstrating the sum of tens of thousands, thousands, hundreds, tens, and ones. Another activity challenges students to fill in missing numbers within equations, fostering their ability to decompose and reconstruct numbers based on place value. Reasoning exercises further engage students with tasks such as counting in increments from a given number and estimating the placement of numbers on a number line without clear divisions, thus enhancing their numerical fluency and critical thinking skills.
