This resource focuses on understanding and building whole numbers up to 100,000. Students will learn to read, write, and identify the value of each digit in various forms: standard form, expanded form, and word form. The activity encourages collaboration through partner verification, improving their grasp of place value and number comparison. It includes hands-on tasks such as building five-digit numbers, discussing the significance of each digit's position, and even creating the largest and smallest numbers possible from a set of digits. This approach fosters a growth mindset by promoting the positive impact of making mistakes and learning from them.
