Concentration: With this game you will need two game cards per word. Mix up all of the cards and place them all face down on the table. You and your child can take turns looking for pair of match sight word cards. If a match is found the player that made the match keeps these cards. If two different cards are located, then both are flipped over and the other player takes a turn. The game is complete when all matches have been made. Remember to have your child identify the words on the word cards as they flip each card over.
You can print out to sets of flash cards from the following website-
I recommend using only one set of words at a time until your child builds up their recognition skills with the sight words. For example, start by playing with the preprimer list. Once your child has built up their proficiency with this set, move on the primer set of words. When they have become proficient on this level, move to the first grade list. For an additional challenge, when they have become skilled at all levels; try having a game using all of the words cards.
