My students need lots of practice to master addition with regrouping, so I created this fun game to help them practice.  This activity supports sol 3.3b, create and solve single-step and multi-step practical problems involving sums or differences of two whole numbers, each 9,999 or less.  The students make a big circle around the room and play a cakewalk style game.  When the teacher stops the music, they sit in front of the closest card and add the two numbers.   Students use their knowledge of place value and estimation to determine if their answer is reasonable.  Movement activities are always a big hit in my classroom!  This game is one of my students’ favorites!
