Place value - Compare objects - Presentation

In a mathematics lesson centred around place value, students are introduced to the concept of comparing numbers using objects. The lesson begins with an exploration of the comparison symbols: greater than (>), less than (<), and equals (=). Students are then engaged in a series of activities designed to reinforce their understanding of these symbols as they relate to numerical values. The first activity prompts them to compare two numbers, such as 452 and 542, using place value counters to visually represent hundreds, tens, and ones. This hands-on approach helps them determine which number is greater by comparing the quantity of counters in each place value column.

Building on the initial activity, students move on to use the comparison symbols to make statements about pairs of numbers correct. They are encouraged to develop and discuss strategies for comparing numbers, such as starting with the highest place value. Further activities involve drawing sets of counters or base 10 blocks to create visual representations that make given statements true, such as one number being less than another. This visual and interactive method allows students to grasp the concept of place value and comparison more concretely. The lesson also includes reasoning tasks where students identify odd numbers out from a series or correct false statements, fostering critical thinking and a deeper understanding of place value and number comparison.
