Solve Half Plus Half Using Rectangle Models: Adding 1/2 + 1/2

To solve this problem, we'll follow these steps:

• Step 1: Verify that both fractions have the same denominator.
• Step 2: Add the numerators of the two fractions.
• Step 3: Retain the common denominator.
• Step 4: Simplify the resulting fraction if needed.

Let's work through each step to add $\frac{1}{2} + \frac{1}{2}$:
Step 1: Both fractions have the same denominator: 2.
Step 2: Add the numerators: $1 + 1 = 2$.
Step 3: The denominator remains the same: 2.
Now the sum is: $\frac{2}{2}$.
Step 4: Simplify if needed: $\frac{2}{2} = 1$.

Therefore, the solution to the problem is $1$, which corresponds to answer choice 2.
