How modeling partialproducts can be used to find the products of greater numbers.

I'm not sure exactly what you mean, but I'm amusing what you mean. You can multiply the smaller number by a part of the bigger number. for instance, 45x5. You can multiply 5x5 and that = 25, then mulitply 40x5=200. Then add 400+25=225. So, 45x5=225.
