Addition Suprise lets your child practice finding sums in an addition table.

To use Addition Surprise, click and drag the number under the door on the left to any square on the grid whose row and column numbers add to that number.  If you are correct, the number will stay on that square as a bear with a balloon pops out of the door and the sum is shown below a “Continue” button. Click this button to reveal parts of the picture beneath all the grid squares whose rows and columns add to the number. The door on the left will shut and a new number will display. If you are wrong, the bear will look in the direction of your answer as “Try Again” is displayed. Click on the button and keep answering until you get it right. Continue playing until the picture is fully revealed, then click “Play Again” to start another round.
