Place value within 100 - Comparing numbers - Presentation

In a series of engaging and educational slides, students are invited to delve into the concept of place value up to 100, with a focus on comparing numbers. The lesson encourages the use of comparative language such as 'greater than', 'less than', and 'equal to', and challenges students to recall the meanings of the symbols <, >, and =. The first activity presents a practical task where students place numbers on place value charts to determine which number in each pair is the largest. For example, they compare 64 with 81 and 90 with 89, using the tens and ones columns to visually represent and assess the size of the numbers.

Further activities include using a number line to identify numbers that are greater than or less than a given reference point, such as 79 or 89, and pinpointing numbers that fall within a specific range. Students are then tasked with comparing numbers by applying the appropriate comparison symbols. This hands-on approach is designed to solidify their understanding of numerical value and the relationship between numbers. The lesson also incorporates reasoning exercises where students create two-digit numbers from a set of number cards, determining which is larger and exploring the various possible combinations. Independent work rounds off the session, prompting students to label numbers on a number line and use base 10 blocks to compare two numbers, further reinforcing their understanding of place value and comparison within the realm of 100.
