Add Up To Four Two-Digit Numbers

This Common Core numbers and operations in base ten lesson covers how to add multiple two-digit numbers. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. In this lesson, students are asked to add the digits by place value. Students are also asked to regroup any group of ten or more with concept demonstrations to show what regrouping means in real terms. In addition to the lesson, there are four pages of Independent Practice with questions modeled after the Common Core assessment items.
