Which of the following concepts do students need to master before learning about math fact families?

While place value is an important foundational concept in mathematics, it does not specifically relate to the understanding of math fact families. Place value helps students comprehend the value of digits within larger numbers, but it does not directly aid in recognizing the relationships between addition and subtraction necessary for fact families.

Skip counting is a technique used to count by specific intervals, such as twos, fives, or tens. Although it is useful for developing number sense and fluency, it does not directly pertain to understanding the relationships within math fact families, which focus on the interplay of addition and subtraction.

One-to-one correspondence refers to the ability to match one object to one number or another object, which is foundational for understanding counting and quantity. However, like place value, it does not provide the necessary understanding of how addition and subtraction work together in math fact families.
