each student 20 index cards. They are to create 10 problems using positive and
negative numbers. Have students write each problem on an index card and write
the answer on another index card.
When they have all 10 problem cards and
10 answer cards, allow them to shuffle the deck and place each card face down
on a table.
I used this during the month of October so we decorated the
blank side of the cards with Halloween or Autumn pictures.
How to play:
Flip over one card, work it out and try to find it's match (the correct answer
card). If match isn't found, turn both cards over and begin again.
into our cafeteria and had a "Concentration Tournament". There was lots
of room and my 7th graders absolutely LOVED it!
