  • I recommend checking the following three links, namely http://www.homeschoolmath.net/download/Add_Subtract_Integers_Fact_Sheet.pdf, http://www.homeschoolmath.net/download/Multiply_Divide_Integers_Fact_Sheet.pdf, and http://amby.com/educate/math/integer.html#mult-div. These sites might serve as good initial resources to concretize math, i.e. help our learners negotatiate meaning in it.
