Place value - 1,000 more and less - Presentation

Lesson 12 in the series focuses on enhancing students' understanding of place value by exploring the concept of 1,000 more or less. This lesson encourages students to compare and contrast the process of adding or subtracting 1,000 to a number with that of adding or subtracting 10 or 100. Through a series of activities, learners are prompted to think critically about which column changes when altering a number by 1,000 and to fill in missing values to demonstrate their comprehension of the concept.

During the lesson, students engage in various tasks that require them to calculate 1,000 more or less than given numbers. They are shown how to add or subtract 1,000 and observe the resulting changes in the thousands place. Activities range from straightforward calculations to more complex reasoning challenges, where students must deduce missing numbers based on provided clues. The lesson plan also includes opportunities for students to use concrete resources to validate their answers, ensuring a deeper understanding of place value and the effects of increasing or decreasing numbers by 1,000.
