To solve this problem, we'll carry out the following steps:
Now, let's perform the calculation:
Starting with 34 blocks, and needing to remove 8 blocks, we calculate:
Calculating this, we have:
Therefore, the number of blocks that will remain is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?

It doesn't matter which specific blocks you remove - just make sure you remove exactly 8 blocks total. The remaining count will always be the same.
Organize your counting! Group blocks by tens when possible, or mark the ones you've removed. You can also count twice to double-check your work.
Yes! Visual models work for any subtraction problem, though for very large numbers you might use base-ten blocks (rods for tens, squares for hundreds) to make counting easier.
Use addition to check subtraction! Add your answer to what you removed: . If you get the original number, you're correct!
