Fact Family Cards
These are cards that should be cut apart and placed in four different boxes. A complete instruction document is included. The children choose from addition/subtraction, multiplication/division, algebraic addition/subtraction, or algebraic multiplication/division. There are vertical versions included so they learn to recognize them in both ways. The sample photo below shows how they would do this. They should use graph paper with only one numeral or symbol in each square - this helps with exchanges too because they should never have more than nine in one square. There are six sheets for addition, six sheets for multiplication and two for each of the algebraic problem sets and the vertical addition and multiplication.
