Addition - Missing Value, 2 Digit, 1 Number (Level 1)

This math topic focuses on solving for the missing value in addition equations involving two-digit numbers, where one of the numbers in the addition is unknown. Students are presented with problems in which they need to determine what number, when added to another two-digit number, results in a specific sum. Each problem provides multiple choice answers, ranging from two-digit numbers to notably larger or smaller values, allowing students to practice discerning the correct calculation from a variety of options. These problems are a component of a broader unit on the addition and subtraction of integers involving two and three-digit numbers.
