Here are links to some YouTube videos that show strategies we are using in class to solve addition and subtraction problems. Please know that the traditional algorithm for addition and subtraction involving borrowing (regrouping) is NOT a 2nd grade skill. When students are prematurely introduced to the algorithm for addition and subtraction, this can cause confusion and difficulty in class. Please watch these videos below to see how we can solve addition and subtraction without the traditional algorithm. Thanks for your support!
