Fact Family Practice Online

EZSchool has a free fact family game online that students use to build four related addition and subtraction problems. The game gives the players three numbers and the students click on them to put them in the correct order in a number sentence. Parents, you can help your children while they play by remind them that in addition you start with the two smallest numbers and in subtraction you start with the largest number. Then remind the students that in fact families, the two smallest numbers switch places. Or, as we call it in our class, the two smallest numbers "flip flop."
