Learnzillion Lesson on Adding four two-digit numbers: https://learnzillion.com/lesson_plans/2717-11-adding-up-to-four-twodigit-numbers-c
Facilitate a class discussion and use guiding questions throughout the lesson.
Explore the bridge strategy. If there are four numbers, then take the first two numbers and add them and then do the same for the
last two numbers. Creating a bridge to each number. Then taking the sums of the last two problems to get your answer.
