This Divide with Three-Digit Divisors Using the Area Model video also includes:
What do benchmark numbers and an area model have in common? An area model is another strategy that learners can use when performing multiplication and division. The key feature of the model shown in the video, is that it represents the product of two numbers as a rectangular region. Using benchmark numbers, number crunchers make an estimate of the product of two numbers that come close to the number being divided.
- Have class members view the link outside of class, saving class time for discussion and practice of skill
- The video is the second in a series that helps learners become fluent in dividing multi-digit numbers using the standard algorithm
- The video introduces benchmark numbers: 5, 10, 15, 20, 25, 30, 50, 100. These numbers help students make good estimations when dividing
- Provides important steps for learning the standard algorithm of dividing multi-digit numbers
