Place Value Subtraction: Remove 5 Tens and 4 Ones from 55 Blocks

To determine how many blocks remain, follow these steps:

• Step 1: Calculate how many blocks 5 tens represent: $5 \times 10 = 50$.
• Step 2: Add the 4 individual blocks being removed: $50 + 4 = 54$.
• Step 3: Subtract the total removed blocks from the original number of blocks: $55 - 54 = 1$.

After performing these calculations, we find that the number of blocks remaining is $1$.

Therefore, the solution to the problem is $1$.
