Adding Multiple Digit Numbers in 2nd Grade

The video tutorial takes place in outer space, where the teacher guides students through solving addition problems using different methods. The first problem involves adding the number of stickers three children have using the expanded form method. The teacher then demonstrates the same problem using base 10 blocks for a visual approach. A second problem is introduced, and the teacher explains how to line up place values and carry over numbers. The video concludes with encouragement to practice more.
