Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
Multiply up to four digits by a one-digit number. Multiply two-digit numbers. Both of these skills can be learned using concrete, visual, and abstract methods. Next, lead this demonstration. Instead of introducing it as learning the 17 times table, I would introduce it as skip counting by 17, from 0 to 170. I think this demonstration is valuable, as it shows students how to memorize a small number of just about anything. It may also increase their confidence in their ability to learn.
