Excel interactive resource: multiples chain

Although this interactive resource could be used just to reinforce vocabulary, I prefer to use it as a dynamic prop to support classroom questioning.

• What's the largest number that a blue cell can hold?
• If the start value is 10 and the end value is 100, how many chains can be made?
• Which pair of start and end values give the largest number of possible chains?
• What is the highest start number that still makes a chain?
• What is the lowest end number that still makes a chain?

The Files

There are two versions of this Interactive Resource:

A three value chain and a four value chain

(Standard click-select will open these Excel files, but to download the files to your own machine: right-click on the link, and choose Save Target As . . . )

Change the values in each blue cell until you have a complete chain of multiples.
