Understanding Division and Cuisenaire Rods

The video tutorial explains division by using Cuisenaire rods to model how many times one number fits into another. It starts with a basic example of dividing six by two and progresses to defining units with colored rods. The tutorial then applies these concepts to solve various division problems, including complex ones, using the rod values. The video emphasizes understanding the division process through visual models.

What is the main concept of division as explained using Cuisenaire rods?

• Calculating the difference between two numbers

• Multiplying two numbers together

• Determining how many times one number fits into another

• Finding the sum of two numbers
