Place value - Comparing objects - Presentation

In a series of engaging and interactive slides, students are introduced to the concept of comparing objects through a variety of activities that are rooted in the principles of place value. The lesson begins with a discussion on what it means to compare, setting the stage for students to explore and understand the comparative size of different quantities. The initial activities involve a straightforward comparison of the number of pencils in two groups, prompting students to determine which has the most or the least, thus applying their understanding of numerical value in a practical context.

As the lesson progresses, the activities become more complex and require students to use cubes to represent and compare numbers visually. They are tasked with arranging objects in a manner that makes comparison easier, such as grouping by tens, which aids in recognising the relative magnitude of numbers. Students learn to use inequality symbols to express their comparisons, further reinforcing their grasp of place value. The slides also incorporate reasoning exercises where students must justify their comparisons or adjust quantities to make numbers equal or to satisfy certain conditions. These activities not only challenge students to apply their knowledge but also to think critically about the relationships between numbers.
