This = That




Build creative equations while practicing math facts


6 cards are dealt face up. Players use addition, subtraction, multiplication and division to make some or all of the first 5 cards equal the value of the sixth card. Parenthesis are available if needed. The scoring system encourages the use of as many number cards as possible. Multiplication and division operations earn additional points. After finding a solution, a "hidden" background picture is displayed.

The software behaves just like the card game it is based on in that it does NOT assure all problems have a solution. While the vast majority of problems can be solved, there may be occasions where the given cards cannot be combined to make the target value.

I encourage students in my class (8-10 year olds) to try and match the target number using all 5 cards. While this is not always possible it helps develop several number manipulation strategies. To further entice students along this line, a 200 point bonus is awarded for using all 5 cards and a visual record of the number of times this bonus has been achieved is recorded on the screen. (This makes it easy for me to look and see who has earned a sticker.)

And... IT'S FREE.
