Additive Identity Addends Answer Key

This worksheet guides students in finding missing addends using the additive identity property. Students begin with easier equations where zero is added to a number, helping reinforce the idea that adding zero does not change value. The worksheet progresses into moderate-level problems in which students determine the number that, when added to zero, maintains the original value. The final section introduces more challenging problems containing decimals, negatives, and variables, encouraging deeper application of the additive identity. Throughout the page, students practice logical reasoning and strengthen skills related to solving equations. The scaffolded structure supports learners at multiple skill levels while reinforcing a key mathematical property.
