Are You Smarter Than A 5th Grader In Common Core Math? Norcross

  Tutoring - Private Lessons

I really wasn’t expecting to get much of a turn out or interaction from this one simple Facebook post.

But I got a ton of comments. Plus even after I declared a winner, the guesses kept coming in days later.

Many answered correctly with an answer of 90,. While a few didn’t pay close enough attention. See they missed that the first number skipped from 6 to 9 multiplying by 8 instead of 10 forgetting to compensate for the number jump.  Still many others apparently guessed randomly.

In case you still don’t understand how to arrive at the right answer of 90, stay tuned. See we must first look at the first two numbers of 2 and 6 to figure out the pattern.

In order to get from 2 to 6, we must multiply 2 times 3. This equals 6.

From there each number pair increases by one, as follows:

  • (3,12) = 3 x 4 = 12

  • (4,20) =  4 x 5 = 20

  • (5,30) = 5 x 6 = 30

  • (6,42) = 6 x 7 = 42

We are missing 7 and 8. But it would be 7 x 8 = 56 and 8 x 9 = 72
