You've found a fantastic THANKSGIVING math enrichment/challenge word problem activity.
This Mayflower Math sheet asks students to use historically accurate information about the Mayflower ship, that the Pilgrims took to land in America, to solve math problems.
The best part about this activity is how much it makes students think. The answers are not right there forcing students to slow-down, re-read and take the time to critically think. I use this every year during Thanksgiving time and my students have so much fun with this challenge.
An optional 3rd page is included, which includes a few vocabulary words to further their understanding. Good for early finishers and vocabulary building!
This activity brilliantly combines ELA, SS, the history of Thanksgiving and Math all in one!
