This resource focuses on teaching students the addition strategy known as 'Compensation.' It aims to enhance students' ability to efficiently solve complex 3-digit and 4-digit addition and subtraction problems by utilizing compensation techniques. The document introduces the learning objective, provides warm-up exercises for identifying 'friendly' numbers, and presents a worked example that illustrates the compensation method step-by-step. Students engage in independent practice, applying compensation to various problems and reflecting on the simplification of math when using 'friendly' numbers. The resource includes advanced strategies that encourage students to compare the standard algorithm with compensation and tackle multi-step problems, culminating in a design-your-own challenge that promotes deeper understanding and mastery of the concept.
