Adult Brain Teasers

Cartoon man questioning, unsure of how to solve our brain teasers for adults. From www.spelling-words-well.com.

These are adult brain teasers ,  but we know that upper grade students will be able to solve them, too, as long as they have good reading, comprehension, and spelling skills!  Why settle for boring, rote comprehension worksheets, when you can really challenge your high-preforming students with brain-straining exercises like this?!?

We recommend you use the printable version of this one so you can use paper, pencil, and an eraser, if needed. As with all worksheets, activities, and brain teasers here at Spelling Words Well, I strongly recommend that you solve this one before assigning it to your students. It helps you spot potential trouble spots your students may encounter. By doing it first, you can confidently steer your fantastic pupils in the right direction.

But here's my challenge to you: Will you be able to get the right answer the first time?


An Impossible Brain Teaser?

Here's a peek at the printable version. The full text also appears below.

Brain Teaser for Adults, titled "An Impossible Brain Teaser"

Carefully read the directions in each line to make changes in the previous set of letters. Write the new letters in the blank on the printable version after each instruction. The first two lines are completed for you.

1. Start with IMPOSSIBLE.                IMPOSSIBLE 

2. Change the second vowel from the left to E.           IMPESSIBLE

 3. If occurrence is spelled correctly, change the 2nd consonant to H. If it is not spelled correctly, change the last consonant to T.                                                    

4. Omit the letters, in order, that spell MESS.

5. Insert CABBAGE after the 1st vowel.                   

6. Change the 2nd I to A.                                          

7. Move the first vowel so that is directly to the right of the 4th consonant.                                                

8. If mischieveous is spelled correctly, omit the first two letters. If it is spelled incorrectly, omit the double consonants.            

9. Change the G to V.

12. Switch the order of the 1st and 2nd letters.         

13. If your letters now form a correctly-spelled word, use the word in the sentence below. If not, review the directions to find any possible errors.
