The 12-week course aims to equip learners with a comprehensive understanding of addition and subtraction up to 100. Throughout the course, learners will delve into the intricate connection between these two operations by engaging in activities that involve composing, decomposing, and identifying missing values in different scenarios. The foundation for this exploration lies in learners' grasp of essential mathematical concepts such as fact families, number bonds, and part-whole relationships.

Through a carefully curated curriculum, learners will gradually develop their proficiency in addition and subtraction within the given range. They will dive into the intricacies of composing numbers, understanding how various smaller numbers can be combined to form a larger whole. Simultaneously, learners will also engage in decomposing numbers.
