Place value - 100s, 10s and 1s 2 - Presentation

In the educational slides for Lesson 7, students delve into the concept of place value, specifically focusing on hundreds, tens, and ones. The lesson utilises a place value chart and counters to help students visualise and understand the value of each digit in a number. They are challenged to think about why numbers are not simply read as a sequence of individual digits but as a whole, where each digit has a distinct value based on its position. For instance, they explore why the number 300506 is not read as such and what the actual value is when represented on a place value chart. Additionally, students are prompted to consider the effect of adding one more ten to a given number and to predict the new total.

Further activities guide the students to use place value counters and a grid to represent various numbers, enhancing their understanding of how digits are grouped into hundreds, tens, and ones. They are also tasked with comparing numbers using the greater than, less than, or equal to symbols, ensuring they appreciate the importance of correct digit placement. The lesson includes reasoning challenges, such as finding different ways to represent a number like three hundred and fifty using place value counters. Students are encouraged to present their solutions as calculations, fostering a deeper comprehension of number composition. Independent work activities involve completing part-whole models and writing number sentences to represent them, building a solid foundation in place value knowledge.
