This is two of my four adding and subtracting task cards for three digit numbers. These two levels are more challenging than my others. Included in this is 12 different task cards for each level, an answer key, and a student record sheet.
The green task cards also have regrouping and four addition problems, four subtraction problems, and four story problems.
The red cards have multiple regrouping for each problem and have four addition cards, four subtraction cards, and four story problems.
Please leave feedback! Thanks!
