Place value - 100s, 10s, 1s - Starter

In Year 4 mathematics, students delve into the concept of place value, focusing on the hundreds (100s), tens (10s), and ones (1s) in a series of engaging starter activities. One of the exercises involves a simple subtraction problem: 932 minus 100, which requires students to understand the significance of subtracting a hundred from a three-digit number. Additionally, the 'Fluent in Four' revision segment prompts students to calculate and identify numbers represented in different forms. For example, they might be asked to determine the result of subtracting 14 ones from seventeen tens, testing their ability to combine knowledge of place value with basic arithmetic.

The lesson also includes a variety of true or false questions designed to challenge students' understanding of fractions and place value. They are asked to verify statements such as whether a unit fraction always has a numerator of 1, and to provide examples of unit and non-unit fractions. Visual representations of currency, such as £1, are used to help students connect mathematical concepts with real-life contexts. Moreover, the activities involve describing groups of place value blocks and performing calculations represented by these blocks, further reinforcing the importance of place value in understanding numbers. The lesson is structured to build a strong foundational knowledge that is crucial for grasping more complex mathematical concepts in the future.
