Students learn to write fact family problems. Fact families all use the same number. Using a whole, part, part mat, students use cube trains to write two different addition problems using the same numbers 2, 8 and 10 (2+8=10, 8+2=10). For the subt...raction problems, students use the same cube trains but start with the whole (10) and then break it down into the two parts (2, 8). Write the subtraction sentences with the same numbers 2, 8 and 10 (108=2, 102=8).
