This topic focuses on practicing the skill of finding a missing value in simple addition problems involving two one-digit numbers. Each problem presents a missing component in an addition equation where the sum and one of the addends are given, and the students need to determine the missing addend. The broader topic also involves addition and subtraction of integers. The level appears to be introductory, aimed at developing basic addition skills with small numbers. Each question offers multiple answer choices, from which the correct missing number needs to be identified.
