Mastering Multiplication

We just finished up our unit on the 4 operations. When I am introducing multiplication and division with large numbers, I first focus on the skill. Then we follow up the skills with an in-depth problem solving unit.

One of the first skills I teach is multiplying large numbers by a 1-digit number. Our standards in Texas include multiplying a 4-digit number times a 1-digit number. This is an important skill because it builds on their knowledge from 3rd grade (2-digit times 1-digit) and lays the foundation needed for 2-digit times 2-digit - which comes next in our curriculum.

We spent a week on multiplying by 1-digit numbers. All of the activities that my kids did were in a Google Slide that I shared through Google Classroom. They worked through the following activities at their own pace:

They started with a video lesson, while completing a student anchor chart. The completed charts go in their math binder.

After the video lesson, they completed a sort. The sort was multiplication problems. They solved them on white boards and then sorted them by odd products and even products. {My kids LOVE to work problems out on white boards!!}

Next they used a deck of cards to create 10 multiplication problems that they solved on white boards and *their favorite part* got to check with a calculator. What! You let your kids use a calculator?? Yep! It keeps them motivated and they have to go back and find their mistake if they see that they get the problem wrong. We also spend a lot of time discussing why they really need to do the work on their own and use the calculator to check.

Finally, they complete a set of task cards. There were 10 task cards. I posted each card around the room. They walked around the room with a white board to work the problems. Then they posted their answers to a Google Form that automatically graded all their work. With a click of a button I could see which kids needed more help before their Friday math quiz (hallelujah!).

My kids love having their assignments in Google and having the freedom to work at their own pace. It also helps me pull students in small groups throughout the week.

More visual? Here's a quick glimpse of the Google slides.

Want to try it in your room? You can get all the materials I used in my Teachers Pay Teachers store. Just click the picture below!

Need white boards for your class? You can find some on Amazon that are pretty affordable. This set has a good reviews (this is an affiliate link)
