Subtraction using compensation for 2nd grade by adjusting one number. Help your students practice two-digit subtraction with regrouping using the compensation strategy! In this 25-card Boomâ„¢ Cards deck, students learn to make subtraction easier by adjusting the subtrahend (the number being subtracted) to the next ten. They subtract the adjusted number and then add back the extra amount to find the correct difference. This deck helps students develop number sense, strengthen mental math skills, and explore an alternative to the traditional regrouping algorithm. Perfect for Grade 2 math centers, independent practice, small-group instruction, and subtraction strategy review.
