G1: VIDEO and Google Form Multiply 2x1 and Multiples
This lesson focuses on multiplying 2-digit by 1-digit numbers and introduces the concept of multiples. Students will learn two methods for solving multiplication problems. The first is the traditional algorithm, where numbers are written vertically and multiplied step by step. The second is the box method, which uses expanded form to break the numbers apart and multiply in sections. ______________________________________________________________________________________________ Video Tutorials – G

Adding and Subtracting by Multiples of 10
One way to add and subtract mentally is to understand the role place value plays. Too often, students are taught only one way to add and subtract by using regrouping as the algorithm. While this knowledge is important, having the number sense to add and subtract two and three digit numbers (or more!) helps the student to visualize what he or she is doing when problem solving mathematically.
