11/10/21 – Math – Multiplying 2 digits by 2 digits
We have been introduced to 2 different ways to multiply 2 by 2 digit numbers. Some of us are familiar with method 1: cross-multiplying and others have found method 2: using expanded form more helpful.
Use whichever strategy works best for you! This lesson should be challenging. Great work keeping up so far! We will continue working towards this on Monday.
Watch this video tutorial and see if it helps you! Create a question yourself to try it out afterwards.
