It’s Palindrome “Week”
The dates December 1-9 form a palindrome when the month is written as 12 and the year is written as 21. So…
December 1 is 12-1-21
December 2 is 12-2-21
December 3 is 12-3-21
BONUS: 12-11-21 and 12-22-21 are also palindrome dates this month!
The date reads the same forward as it does backwards. This doesn’t happen often, but it’s happening now until December 9!

Mean Absolute Deviation (MAD) is how far, on average, all data values are from the middle.
To find the MAD, you can follow 3 easy steps:
- Find the mean of the values
- Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs which is also the absolute value)
- Then find the mean of those distances
For this Math Mini Spark, you’ll be finding the MAD on a spreadsheet. Follow the steps below.
Step 1: Make a Copy of this Spreadsheet by clicking the link: https://docs.google.com/spreadsheets/d/1ndcgCZ1EeVcKausxtkmBkONVfCeilbQNE6ukdUCWYk8/copy
Step 2: Watch the video below and complete the steps shown in the video on your own spreadsheet.
NOTE: This mini-spark can be used as 1 spreadsheet lesson for the Spreadsheet Superstar Badge.

In your math notebook, complete the following tasks:
- In the episode, “Have You Seen This Snail?”, SpongeBob SquarePants is given a challenge of hitting a paddle ball 29,998,559,671,349 times in a row. This causes SpongeBob to neglect Gary (his pet snail) and so Gary leaves. Write this number out in words.
