Add 2-digit numbers using a number line to find the sum!
2nd Grade - Math - Add within 100
About This Skill
Where will you land on the number line? Grade 2 students practice adding 2-digit numbers by making 'jumps' for tens and ones to reach the sum. As questions adapt to their progress, children use visual models to break apart numbers and move step-by-step toward the final answer. With instant feedback on every jump, this practice builds flexible mental math strategies and a strong understanding of place value.
