How to Teach A Reluctant Boy Subtraction

alec vanderboom

Our Kindergarten Word Problem of the Day:

"If there were 10 people on an airplane that landed on Jurassic Park Island and a mean Dino ate 3, how many people are left?"

To figure out the answer to 10-3=7, Alex drew a picture of 10 people running from a fierce Dino and then drew a bloody red x on three of the victims. I'm not sure how thrilled our home school reviewer will be with this teaching method, but it works! My son got the tricky conception of subtraction mastered in one day. Hurrah for our new invention of "Dino Math!"
