This material focuses on understanding the place value of each digit and performing subtraction operations using a clear and structured approach. By expressing numbers in expanded form, teachers will demonstrate the activity and this would let the learners to strengthen their grasp of subtraction concepts, enhance their arithmetic skills, and develop a deeper understanding of mathematical operations within the context of tens and ones.
Objective
To provide a comprehensive and hands-on approach to subtraction, enabling students to master subtraction techniques and deepen their mathematical understanding.
