This depends on your scholars and their current understanding of integer operations.

  • If your scholars are at the beginning levels, Level 1 would be best.
  • If your scholars understand the concepts but simply need more practice, Level 2 will do the job.
  • If your scholars are ready for a challenge, by all means go for Level 3!
  • If your scholars are at various levels (which is most common), a classroom set of Levels 1, 2, & 3 will enable you to create a differentiated learning experience where all scholars are engaged at the appropriate level. This will create a fun learning experience for all!

What are “Integer Counters”?

Hands using integer counters
  • Integer counters are tangible representations of positive and negative integers.
  • Each blue integer counter represents +1.
  • Each red integer counter represents -1.
  • A combination of a blue integer counter and a red integer counter represents a sum of 0. We call this a “pair of zero”.
  • Integer counters can be used for scholars who are still making sense of integer operations in Integer Addition Level 1 and Integer Subtraction Level 1. If a scholar attempts a level 2 game and is still dependent on the integer counters, it might be helpful to conduct the “Checks for Understanding” from the booklet included in the deck.
  • Once a scholar has graduated to the level 2 and level 3 decks, integer counters should not be necessary.

For more information on the use of the integer counters, see the Instructions and Videos tab.
