Using Manipulatives in Addition

The video tutorial demonstrates solving two addition problems, 47 + 34 and 14 + 22, using manipulatives like tens rods and ones cubes. The instructor explains how to represent numbers with these tools, combine them, and count to find the sum. The tutorial emphasizes the concept of regrouping ones into tens when the count exceeds ten.
