#64: Divide by Zero?

Math Mini Sparks

So for now is sounds like we can’t divide by zero, but maybe there might be a rule that mathematicians could be tweaked to make it possible?  Check out this math mini spark and see what you think about this idea.

Spark your math thinking!

  1. Set up your math mini spark recording page: #64: Why can’t you divide by zero
  2. Watch this video that explains why you can’t divide by zero. Write down 5 ideas from the video.

3. Record 5 vocabulary terms with definitions from the video.

4. Read this info page from Math is Fun. Record 5 details from this page.

5. Share your math mini spark recording page with your teacher/EY coordinator.

#63: Can you KenKen®?

Learning Opportunities, Math Mini Sparks

The goal of KenKen® is to fill the whole grid with numbers, making sure no number is repeated in any row or column. If it’s a 3×3 puzzle, you only use the numbers 1-3.  If it’s a 4×4 puzzle, you only use the numbers 1-4. The “cages” are outlined in dark black.  The top left corner of each cage has a “target number” and a math operation (+ – x /).  The numbers you put in the cage have to make the target number. Sometimes a cage is one square in which case, it’s a freebie.

  2. A palindrome is a word, phrase, number, or other sequence of symbols or elements, whose meaning may be interpreted the same way in either forward or reverse direction (i.e. mom, wow, racecar, 10501, etc.).  Create a list of palindromes using this resource.
  3. Did you know that any number can be written as the sum of 3 palindromes?  It’s true!  Check out this Numberphile video. Record 5 details.

 

4. On your recording sheet, answer these questions after watching the video

  • Describe the specific example used in the video to demonstrate how to write a positive integer as the sum of three palindrome numbers.
