Courses and Methods That Help You Succeed

In this module, students strengthen their foundational number skills. They practice addition and subtraction within 20, work with place value using expanded form for 3-digit numbers, and begin multiplication by learning to multiply by 2, 5, and 10. Students also explore the concept of multiplication through equal groups, understanding that 'g groups of k each' equals g × k. These skills prepare students for more advanced operations.
