Dan Meyer tweeted a recommendation, and on November 4th Ashley Minton tweeted a different variation that uses spinners (pictured below).

The dots were connected for me yesterday as this same robust activity appeared in Boaler's article that was shared by Common Core Math Resources on Facebook. I knew I just had to try it and share it with others! How Close to 100? is one of several resources provided in the must-read article- Fluency Without Fear: Research Evidence on the Best Ways to Learn Math Facts by Jo Boaler. (The template can be easily downloaded from the YouCubed website). I highly recommend anyone concerned with computational fluency strategies to read this article and grab the provided resources. The content is in alignment with another favorite article I've read from Linda Gojak called Fluency: Simply Fast and Accurate? I Think Not!
I introduced How Close to 100? in a 4th grade classroom today! I inserted a slightly altered template into a sheet protector for each group, gathered enough dice and dry erase markers, and made additional copies for the students to use for practice at home. (Sheet protectors and dry erase markers make repeated practice sustainable by reducing the amount of paper needed.)
|Each player used a different color dry erase marker and shared a template to increase the opportunities for discourse.|
|The player with a total sum closest to 100 was the winner!|
