If we have 17 blocks in total and we remove 14 of those blocks, how many blocks remain? Remember you can break down a row of 10 blocks into single units.
We need to determine how many blocks are left after removing a certain number from a total.
First, let's identify the given figures:
The formula for finding out how many blocks remain is subtraction:
Remaining Blocks = Total Blocks - Blocks Removed
Substituting the given numbers into this formula:
Remaining Blocks =
We perform the subtraction:
Therefore, after removing 14 blocks from the total of 17, we find that the number of blocks remaining is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
You start with 1 tens block and 7 units, but need to remove 14 blocks total. Since you can't remove 14 from just 7 units, you must break down the tens block into 10 individual units first!
One tens block equals 10 individual unit blocks. So 1 tens + 7 units becomes 0 tens + 17 units. Now you can easily remove 14 units!
Yes! The picture shows exactly what you're working with. Count carefully - you'll see 1 long block (representing 10) and 7 small blocks (representing units).
Start by converting everything to individual units: 17 total units. Then remove 14 units. Count what's left - that's your answer!
Add the blocks back together: . If you get your starting amount, your subtraction was correct!
