Addition and Subtraction - Add and subtract multiples – 1s, 10s, 100s, 1000s - Presentation

This educational resource provides a comprehensive set of activities aimed at enhancing students' fluency and reasoning skills in adding and subtracting multiples of 1s, 10s, 100s, and 1000s from four-digit numbers. The lesson encourages students to explore and understand the impact of these operations on the different place value columns within numbers. Through a series of engaging activities, learners are prompted to consider what changes occur in the number when adding or subtracting multiples of 10, 100, and 1,000, fostering a deeper grasp of place value and number manipulation.

The activities are designed to be interactive, with students using place value counters to visualise and carry out the arithmetic operations. They are tasked with adding and subtracting specific values, such as adding 2 thousands or subtracting 4 tens, and then observing the resulting changes in the number. This hands-on approach helps to concretise abstract concepts, allowing for a clear understanding of how each digit within a number is affected by addition and subtraction. Students are also encouraged to discuss and reason through their answers, further reinforcing their learning. Whether working independently or in groups, these activities cater to a range of learning styles and promote critical thinking.
