Teaching Then and Now

Concentration
Click cards to try to uncover matching pairs of cards. If you click a hidden card once, it is uncovered to display the item on its other side. If you click the card a second time, the item turns back over and is hidden. Try to only uncover two hidden items that match.


If your match is correct, both items will be displayed with two green check marks and you will receive one point.
If your match is wrong, both items will be displayed with two red "x" marks and you will also receive one point.
Your goal is to match all of the cards with their corresponding matches while earning the least points possible.
