Students must be able to determine the product of a number and 10 or a number and 100. They will do this using and their understanding of place value. 

Brizza told Tiandre that she could find the product of 394 and 10 (or even 100) without actually multiplying, but Tiandre didn’t believe her. Use the distributive and commutative properties of multiplication to show Tiandre why Brizza was correct.

 

Hint  

Possible Solution 

Supporting Standard 

 

4.4 Number and operations. The student applies mathematical process standards to develop and use strategies and methods for whole number computations and decimal sums and differences in order to solve problems with efficiency and accuracy.
