Solve 1200 + 940 Using Number Line Jump Strategy

Let's solve the problem step-by-step using a number line approach:

• Step 1: Start at the number 1200, the initial value.
• Step 2: Follow the number line jump adding 800 to 1200. The calculation is:

$1200 + 800 = 2000$

• Step 3: Jump again by adding 100 to the current result (2000):

$2000 + 100 = 2100$

• Step 4: Finally, perform the last jump, adding 40 to get the final result:

$2100 + 40 = 2140$

The number line effectively helps in visualizing the addition process through incremental steps.

Thus, the sum $1200 + 940$ results in $2140$.
