Guess the Grade - Answer Now Posted!

Hello folks! Time for a bloggeractive moment.
Today, I was teaching the following:

3 + (-2) = ?

Guess the grade I was teaching and earn a cookie (from your own cookie jar).

UPDATE: The blog has been buzzing with anticipation to find out the answer to the above question. The grade, as it turns out, was 7th and 8th grade. In the defense of the children, it was a "remedial math" class and about 80% of them were able to answer the questions on the worksheets with only some difficulty. Quite interesting to me was that multiplication of integers with positive and negative values seemed a bit easier for most than the adding of integers. Perhaps because with the multiplying, they had their multiplication chart for numbers 1 through 12. Most distressing, however, was when students had difficulty spewing out the answer to 3x5 or other simple multiplication problems without the use of their charts.

We must do better!
