This math topic focuses on identifying and understanding fact families through addition and subtraction problems. Students practice building fact family triangles based on provided addition and subtraction facts involving 1 and 2-digit integers. Each problem is designed to help students recognize and visualize the relationships between numbers in a fact family, essential for enhancing their integer operation skills. The examples prompt students to deduce the correct fact family triangle that corresponds to a specific arithmetic fact, effectively strengthening their number sense and arithmetic reasoning.
