Solve 49 + 27 Using Number Line Jump Strategy

To solve the addition problem $49 + 27$ using a number line, follow these steps:

• Start at 49 on the number line.
• Decompose 27 into tens and ones: $27 = 20 + 7$.
• First jump 20 units forward from 49: $49 + 20 = 69$. Now you're at 69.
• Next, jump 7 more units forward from 69. Break this into a jump of 6 then 1:
• Jump 6 units: $69 + 6 = 75$.
• Jump 1 more unit: $75 + 1 = 76$.

Thus, the final position on the number line is 76. Therefore, the solution to the addition is $76$.
