Common Core Math - Grade 4
Lesson Plan
Fluently add and subtract multi-digit whole numbers using the standard algorithm
Goals / Objectives
Add multi-digit whole numbers (up to 1,000,000) using the standard algorithm, including problems that require regrouping (carrying) across multiple place values
Subtract multi-digit whole numbers (up to 1,000,000) using the standard algorithm, including problems that require regrouping (borrowing) across multiple place values
Explain why the standard algorithm works by connecting each step to place value -- each column adds or subtracts units of the same size, and regrouping trades 10 of one unit for 1 of the next larger unit
Handle subtraction from numbers containing zeros that require regrouping across multiple columns (e.g., 5,000 - 1,237)
Check the reasonableness of addition and subtraction results using estimation and by using the inverse operation (adding to check subtraction)
