More and Less
More and Less:
Comparing numbers is the ability to determine more and fewer, greater than, less than and equal to, and putting a group of numbers in order. Comparing numbers is a relational number skill where students work with numbers in relation to each other.
Videos for Educators
Important Information:
An understanding of the concepts more, less and the same and an appreciation of how these are related. Children at this stage develop these concepts by comparison and no counting is involved.
This is important because these concepts lay the foundation for children to later develop an understanding of the many ways that numbers are related to each other.
Children often have some concept of more; this needs to be extended and refined. Less is a more difficult concept and understanding can be developed by pairing the terms less and more to help develop an understanding of the relationship between the two.
Examples of what students might say: "I think the red box has more because it looks more full."
Strategies to Support Student Learning:
Putting pictures of items in order from smallest to largest, based on quantity, and counting them forwards and backwards.
Organizing objects in order, without numbers at first, then adding the symbols later.

This game provides opportunity for students to subitize in a variety of ways. Bingo card representations include numerals, die dot patterns, raised fingers and five-or ten-frames. (Lawson, 159)
This partner game provides opportunity for students to subitize a standard die while also strengthening their early counting skills in order to win the 'tug of war.' (Lawson, 159)
The object of the game is to be the first player to fill all 50 squares on the game board. Players take turns rolling the die, then puts that number of chips on their game board, one per square. The game ends when one player successfully fills all squares on his or her game board; or, when played cooperatively, when all game boards are filled. This game can be played as early as Kindergarten, but you may consider using game boards with only 20 or 30 squares, then giving each child 20 or 30 chips. (Lawson, pg. 160)
Use square tiles or linking cubes, take turns building towers on a game board. The towers are constructed by adding the number of tiles or cubes that have been rolled on the die. Pay close attention to building the towers to the correct height. The game ends when one player successfully fills all the towers on his or her game board. (Lawson, pg. 161)
