The primary objective of this course is to enhance learners' mastery of addition and subtraction by utilizing their understanding of place value. Throughout the course, learners will develop fluency in these operations while incorporating efficient strategies for solving different types of problems. These strategies include skip counting, counting on, counting back, and making a ten.

A crucial aspect of the course is fostering learners' ability to identify and utilize the most appropriate strategy for a given problem. By honing this skill, learners will become more efficient problem solvers, able to tackle arithmetic tasks in a timely manner.

Another key aspect of the course is helping learners make connections between the conceptual representation of computations and the abstract representations of sums and differences. By understanding the underlying concepts behind these calculations, learners will be better equipped to perform calculations involving sums and differences up to 1000.

The course is designed to be completed over a 12-week period, allowing learners ample time to develop and reinforce their mathematical skills. The curriculum and instructional materials are structured in a way that promotes a gradual and scaffolded progression of learning. This approach helps learners build a strong foundation in place value and develop a range of strategies for addition and subtraction.

Overall, this course aims to enhance learners' computational fluency and problem-solving abilities by leveraging their understanding of place value and teaching them efficient strategies for addition and subtraction. By the end of the 12-week course, learners will have developed the skills necessary to tackle a wide range of computational problems with confidence and accuracy.
