Integer addition and subtraction is explained using two different approaches:
1. Plus and minus counters with a workboard
2. Number line rules
The presentation covers several different examples of addition and subtraction. The counters and workboard are not included in this presentation and are not needed to use this presentation, but they are available for purchase (see below).
This presentation could be used as part of an introduction to integer addition or subtraction, or as a review at the beginning of Algebra 1.
The plus and minus counters, together with a workboard and practice problems, are sold separately here:
