Here is four different math task cards that focus on adding and subtracting within 100 and 1,000. Also, students will focus on writing numbers in expanded form and compare two digit and three digit numbers. Each color is a different level. The purple has no regrouping, blue has some regrouping, green has students regroup twice, and the red cards have students regroup and have some multiple step problems. Each level contains 12 different task cards, a student answer sheet, and an answer key. Happy teaching!
