Place value - Compare numbers - Presentation

In a comprehensive lesson on place value, students are tasked with comparing numbers to deepen their understanding of numerical value. The lesson starts with an engaging question, prompting students to think of two 3-digit numbers and determine which one is greater. This sets the stage for the main activity, where they are presented with pairs of numbers in various forms, such as written words and numerical expressions. Students are instructed to circle the greater number in each pair, encouraging them to apply their knowledge of place value to make comparisons. For example, they compare 'nine hundred and two' (920) with '500 and 63' (568), and '7 hundreds and 6 ones' with '76 tens'.

The lesson's second activity challenges students to use comparison symbols (<, >, or =) to correctly complete given statements, further reinforcing the concept of numerical magnitude. They must determine whether numbers like 399 and 501 are less than, greater than, or equal to each other. Additionally, the lesson includes reasoning problems that require students to apply logical thinking and their understanding of place value. One problem involves determining the possible number of sweets in a jar, given the quantities in other jars. Another problem asks students to deduce a mystery number based on clues about its digits and their sum. Through these activities, students learn to use place value knowledge to compare numbers and solve problems, developing critical thinking skills in the process.
