Maryland VSC: 4.6.C.1.b. Use a minuend and subtrahend with no more than 4 digits in each and whole numbers (0-9,999)
The purpose of this lesson is for students to use prior knowledge of subtracting whole numbers and regrouping, and applying that knowledge to subtracting whole numbers with no more than 4 digits in each whole number, and regrouping up to three times. Students will use straw manipulatives to model borrowing and regrouping when subtracting the whole numbers. Then, students will use a standard algorithm to solve the subtraction problem in order to check their work.
