This is a set of 2 complete math center games. The first game can be used as a memory game or as a matching game. Match the base ten block representation to the written numerals and the number. Matching the cards in 3 ways helps solidify the concept. Cards can be turned face down and used as a memory matching game or can be shuffled and matched. The second game compares 1 to 3 digit numbers. Number cards are included and greater than and less than cards are as well. A recording sheet is included to hold students accountable. Both games are CCSS aligned and can be used all year long as a math center or small group activity.
