The EY Team would like to invite learners of all ages to take the 2021 Summer Bucket List Challenge! We hope you have fun resting, relaxing, learning & growing this summer!
Vi Hart is one of my absolute favorite mathematicians and doodlers (I’m sure she has many more talents, but those 2 are the ones I admire the most). Watch some, part, all of the videos below and create a doodle for this week’s weekly challenge (also probably the last challenge for the 2020-21 school year). Don’t forget to submit your doodle using the link below!
The Munroe-Meyer Recreational Therapy Program would like to invite you to volunteer!
The program offers student volunteers, ages 13 to 25, hands on experience interacting with children and youth with developmental disabilities. If you are interested in health care or teaching, this would be a great opportunity. Find out more and/or apply by clicking the link below.
The Luhn algorithm or Luhn formula, also known as the modulus 10″ or “mod 10” algorithm, was developed in the 1960s as a method of validating whether or not identification numbers provided by a user are accurate.
Spark your math thinking!
Set up your math mini spark recording page: #83 The Luhn Algorithm
Look over this chart. What do you notice about each of the rows?
3. Read this article about the formula and how it is used in real life to catch errors when shopping online. Choose 2 of these questions to answer with at least two sentences. Remind your teacher that the key can be found in the math mini spark folder.
What is the main purpose of the Luhn Algorithm as described in the text?
How does the algorithm determine if a credit card number is valid after a user inputs it incorrectly? Provide specific steps involved in the process.
What kind of errors might still pass the Luhn Algorithm, even if the sum is a multiple of ten? Explain why these errors can occur.
Why do online stores request additional information, such as the expiration date and card verification number, even if the Luhn Algorithm is used? What does this suggest about the reliability of the algorithm?
3. In this video you will learn how to use the Luhn Algorithm. Make the table on paper as you watch.
4. Optional: Research the creator Peter Luhn and make a timeline with 5-8 details.
5. Optional: Complete the math challenge presented by CEMC math . Print it, read the page and look at the different strategy that they present to you. Work on the challenge presented.
6. Check your work with this answer key. Remind your teacher that the key can be found in the math mini spark folder.
7. Share your math mini spark recording page with your teacher/EY coordinator.
For this week’s Weekly Challenge, you’ll have an opportunity to learn about various types of Engineers, complete some math problems, and possibly win PRIZES!
There will be 5 problems posted this week (linked below) and each problem has multiple parts. You can submit your answers to the problems anytime during EWeek (Feb 21-27), so don’t panic if you get started late!
Each correct answer you get will be a ticket in that day’s prize drawing.
Everyone who participates will be entered in a prize drawing! Submit answers to at least one Problem of the Day and you’ll be entered to win, even if you don’t get correct answers.
Each individual prize drawing winner will get a $10 Amazon gift card and each group drawing winner will receive a $50 gift card to the MATHCOUNTS store!
