Second Grade 2 - Adding Whole Tens (2 digits)-Exercise 2

This worksheet focuses on addition for second graders, specifically adding whole tens with two-digit numbers. Students practice adding pairs of tens, such as 40 + 70 and 60 + 30, which helps reinforce their number sense and mental math skills. This activity is excellent for building confidence in addition and can be used as a warm-up exercise, during math centers, or for independent practice. Encourage students to verbalize their thought process as they work through the problems to deepen their understanding of addition strategies.
