Today, we are taking bigger steps with our multiplication. We are multiplying 3 and 4 digit numbers! It is very easy to overlook numbers when doing something as simple as addition. I would like the students to check their work by doing the standard algorithm AND the area model. They may also do the problem on a calculator to triple check :]. Sometimes it is exciting for them to be able to use the calculator and see that they got the same answer... very gratifying!
In problem b, we are multiplying 273 and 306. When we decompose (break up) 306, we have 300 and 6. If we were to write tens, we would put 0. This would be okay, but it is also extra work, so we may as well leave it out!
* When doing the standard algorithm, ensure your student is not forgetting the place value of each number which adds a zero on each line after the first. If this sentence is confusing, take a look at the picture where I wrote "Don't forget".
Thank you!
