When subtracting technology is a plus answer key
Subtraction is one of the first mathematical operations to be taught to students. Though mastery of the standard algorithm isn’t expected until grade 4 per Maine Learning Results and Common Core State Standards, students should be exposed to a variety of strategies much earlier. Compensation, decomposition, and expanded notation are just a few of the strategies that can be used to help students strengthen their number sense skills while building an understanding of place value.
When you subtract two numbers, the result is called the difference. The smaller of the two numbers is known as the minuend, while the larger of the two is known as the subtrahend. Subtraction is used in practical problems all the time, so it’s important that students understand the different parts of a subtraction problem.
