Description:

This interactive Flash version of the familiar game Concentration ("pelmanism" in the UK) helps a single user practice addition facts while developing memory and concentration skills. The player can choose an array of 16, 20, or 24 cards, which appear face down. The goal is to flip two cards at a time to match all the 2- or 3-addend expressions with their sums as efficiently as possible. A scoring feature discourages random guessing. Printable versions of the game cards are available to download.
