Excel Interactive Resource: Multiples Chain
Stage: 3 and 4
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?
There are two versions of this Interactive Resource:
three value chain
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.
