Play Memory Game 2 to practice words derived from the Latin root cedere, which means 'to go' or 'to yield.' They include access, inaccessible, concede, concession, excessive (too much!-- it goes over the limit!), precede and precedent, proceed, proceedings, process, and procession (each with a different meaning), recession, succession, and success.
If you want to play this game from a mobile phone and your screen is too small to show the regular 4x3 card grid, try the mobile version of this page with a long, narrow (2x6) grid of cards to turn over. (You'll just need to scroll a little to play.)
This game won't teach them all-- but it will give you a good start. There are more (as well as a different way to practice matching some of the same words) on Important Latin Roots.
Instructions: Your goal is to turn over 2 cards that belong together: a word and its (simplified) definition. There are twelve cards in 3 rows. Players (if you are playing with someone) take turns choosing two cards to turn over. If the cards match, they will stay face up, and the player who chose them wins that pair.
If they do not match, they will turn back over. (Try to remember their locations. If you find a match for one of them later, you want to be able to find it again.) Continue to turn over two cards at a time until all have been matched. The player with the most matches wins.
If you are playing with others, the object of this game is to win the most pairs of cards. By yourself, see how quickly you can match all the words with their definitions. Play it again to watch your speed go up. (Card locations will be different. Memorize meanings, not locations!)
Again, Important Latin Roots has more information on words made from cedere and five other very useful roots. Roots, Prefixes, and Suffixes and its links to other pages explain how words are put together.
