Double Digit Multiplication

 

Double Digit Multiplication

Your kiddo has been working on double digit multiplication. We have learned a couple of ways to calculate these types of problems. I wanted to be sure that you were aware of the methods introduced so that you can support your kiddo at home. We learned the standard algorithm/bow method and the box/partial product method. Below are images of the steps/notes that your kiddo uses for both methods.

Here is a link that can help demonstrate and explain the connection between the box/partial products method and the bow/standard method:


Box/partial products method does a good job of keeping place value in double digit multiplication. This concept can be lost when calculating using the standard method. It is also less overwhelming and therefore seems easier to some kiddos. I do not care which method your child uses as long as it make sense to them and they are consistently successful. Ask them to explain the method that they like the best to you!

Here are some websites that allow you to practice these skills:





Here is a fun song explaining the standard method:
