Student Tutorials for Multi-Digit Multiplication

We have been sharpening our multi-digit multiplication skills! In class we made posters to share the different strategies we use to solve these larger multiplication problems. At the end of this post is a slide show with some of our posters.

But first, here are a few video tutorials showing a few of the main strategies. These were made by the students using the Explain Everything app on our iPads. The students did a fantastic job being our first to use the app. They learned a lot, and they will be able to help the rest of the class make even better tutorials as we get more familiar with the app.

Below is a demonstration of the "Box" strategy by Lily:

In the next video, Ivy demonstrates the "standard algorithm" or "stacking" strategy:

And, finally, Ryan gives a demonstration of "changing a number" to make an easier equation"

Thanks again to Lily, Ivy, and Ryan for trying out the app and making our first tutorials! Stay tuned for more videos about division strategies.

Here is the slideshow of some of our posters highlighting more ways to solve 35 x 28:
