Place value - Comparing numbers - Presentation

In a presentation aimed at reinforcing the concept of place value, students are tasked with comparing numbers using the mathematical symbols for greater than (>), less than (<), and equal to (=). The lesson begins with a review of these symbols and their meanings, setting the stage for the activities that follow. The first activity requires students to determine the relationship between pairs of numbers or mathematical expressions by inserting the correct comparison symbol. This activity involves numbers and simple addition problems, challenging students to apply their understanding of numerical value and basic arithmetic to make accurate comparisons.

As the lesson progresses, students delve into reasoning exercises that further test their grasp of place value and comparison. One such activity asks them to identify all the possible numbers that can fit within a given range, such as finding numbers between 13 and 20. Another reasoning challenge presents a puzzle where students must fill in missing numbers using a predetermined set of digits to complete a series of comparisons. Independent work includes tasks where students must determine the truthfulness of statements using comparison symbols and add numbers to make sentences true. Throughout these exercises, students are encouraged to justify their answers using concrete resources or diagrams and to consider if there might be multiple correct answers or if calculations are necessary to determine which number is greater.
