Subtract 2 Tens from 46 Blocks: Place Value Practice

To solve this problem, we'll proceed through the following steps:

• Step 1: Identify how many blocks are represented by "2 tens".
• Step 2: Subtract the number of removed blocks from the total number of blocks given.

Now, let's work through each step:
Step 1: "2 tens" equates to $2 \times 10 = 20$ blocks.
Step 2: We are removing 20 blocks from the total of 46 blocks. Using subtraction, we have:

Therefore, after removing 2 tens (which is 20 blocks), the number of blocks that remain is $26$.
