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

In a Year 3 mathematics lesson, students delve into the concept of place value, focusing on hundreds, tens, and ones. The lesson begins with a straightforward addition problem, where pupils are tasked with calculating the sum of 66 and 20, reinforcing their understanding of adding tens to a two-digit number. A 'Fluent in Four' revision segment further challenges students to recognize and represent numbers using the place value columns. They practice their skills by adding three ones to four tens and determining the resulting number, which requires a grasp of the base-10 system and the ability to combine units of different magnitudes.

The lesson continues with exercises that encourage students to apply their knowledge of place value in various contexts. They are prompted to complete a bar model, a visual tool that aids in conceptualizing mathematical relationships. Additionally, an activity that involves moving a counter on a grid helps to visualize the concept of direction and distance in a numerical sense. The materials include a variety of examples and tasks, such as finding the total value represented by a collection of £2 coins, which amounts to £12, or understanding the time as half-past ten. These exercises are designed to be engaging and to solidify the students' comprehension of place value in practical scenarios.
