Sample Activities:

 

·        Young students use dot pattern cards or dominoes to practice more, less, and same. For example, given a card with 6 dots on it, students use counters to make a set that is more, another that is less, and one that is the same. They can then label the sets with cards that show the appropriate words. With dominoes, students work in pairs to compare the dots on the two halves and state which is more and by how much.

 

·        Students play the old favorite card game war with either dot cards or with a deck of regular playing cards minus the face cards. Every now and then, the rule changes so that the student with the card that is less wins the play.

 

·        Students play Guess the Point. A long number line with endpoints of 20 and 75, for example, is drawn on the board where all of the intermediary points are labeled above the line. The labels are then covered by a long piece of paper that can be lifted to reveal them. A student places a finger somewhere on the line and others must estimate the numerical label of the point chosen. The paper is then lifted to check the accuracy of their responses.

 

Kidspiration Activities:

 

·        Use the number lime symbol and the create SuperGrouper tool to create number line SuperGrouper categories to sort whole numbers
