Our Multidigit Arithmetic +/- lesson provides students with a step-by-step strategy for adding or subtracting large numbers. Students should already be familiar with place value, as it is stressed repeatedly throughout the lesson. During this lesson, students are asked to complete an interactive activity in which they draw random numbers from a bag and either add or subtract them. Students are also asked to complete practice problems on their own in order to demonstrate their understanding of the lesson.
At the end of the lesson, students will be able to fluently add and subtract multi-digit numbers.
