A great math extension for Leap Day!
Give students the 3 rules to figure out past and future Leap Years and have them answer the mystery question: When were the last Leap Years and when will the next one be? Finish up with the bookmark and a jump rope song!

This craftivity will be FREE for an entire year! Woo hoo.

After which time, it will be up-dated and put in my TpT shop.

Click on the link to see the new, completely re-done, 26-page, Leap Year Bookmark Math Craftivity packet, which now includes 10 bookmark options, background information for more math extensions &  data analysis, plus an answer key to the year 2400.

For your convenience, I've included a PREVIEW here.
