Task cards for second and third grade students to practice subtracting three digit numbers with regrouping.
Each of the 30 task cards
includes a strategy for students to use in solving the problem (open number lines, expanded form, model with base ten, standard algorithm, show two strategies, and student's choice).
This is an engaging way to get students to practice solving 3 digit subtraction with regrouping and to use a variety of different strategies in their problem-solving. I've included strategy explanation pages to illustrate how to use expanded form, open number lines, and model with base-ten. You can post these for students, use them to create class anchor charts, or just as a visual for yourself.
I often tape 10-15 different task cards up around the room and my students walk around with a partner, working together to solve each problem. I show them how to fold a piece of blank paper into fourths or sixths to use as a recording sheet. They just write the number of the task card they're working on, copy the problem into the square, and then show their strategy. It's an easy, low prep way to get kids up out of their seats and practicing solving three-digit subtraction. My students LOVE doing this!
