Number Sense Games

## Featured Games:   Contig and Contig Jr.

In the Contig Game students toss three dice.   They use those three numbers and any operations to form a number on the game mat.   Players earn an extra point for each covered number the new number touches, so students quickly learn to search for the best move that will yield the maximum possible points.   The instructional benefit of the game is that students try many different combinations in search of that best move.

Contig Jr. is designed to provide that same format for younger students who need to develop mastery of addition and subtraction facts.

# Contig Jr. Game

Contig is a very effective game that encourages students to master basic facts (+ - x /) in order to get the most points with each play. Contig Jr. is designed to provide that same format for younger students who need to develop mastery of addition and subtraction facts.

 How to play Contig Jr.: Player 1 tosses 3 dice. He/she then uses those 3 numbers and the operations of addition and subtraction to make an answer that is on the game board. For example, if the player threw 3, 5 and 2, the player could form these numbers. 3 + 5 + 2 = 10 3 + 5 - 2 = 6 3 + 2 - 5 = 0 5 + 2 - 3 = 4 The player may mark an X on any one of these numbers (10, 6, 0 or 4) anywhere on the board. He/she gets a point for being able to make an X on the game board. If his/her X touches other X's around it, the player gets an additional point for each X it touches (even at corners). Players learn to select the number that touches the most other X's to get the most points. With more experience, players learn to try out all of the different possible combinations, as listed above, in search of the number that will give them the most points. When players reach this stage, it is optimal play for the development of "fact power" as they mentally rehearse lots of different combinations in search of the perfect move.

These games provide mixed practice in all operations as students try several different combinations in search of the winning move.   Because players have the opportunity to score extra points, they are highly motivated to mentally calculate many options in search of the move that yields the most points.
