توضیحات
Some of the numbers are missing in the icy fact families. Students add, subtract, or use math facts they have memorized to fill in the missing numbers. In this fact family practice worksheet, students show they understand the inverse relationship between addition and subtraction (for example, an opposite number sentence for 4 + 7 = 11 is 11 − 7 = 4).
