In the picture we have a total of 35 blocks. Comprised of 3 tens and 5 ones. If we add a further 5 ones how many blocks will we have in total?
Given the problem, we begin by identifying that the original number of blocks is 35, composed of 3 tens and 5 ones.
Step 1: Identify the current number of tens and ones: - blocks means tens and ones.
Step 2: Add the additional ones: - We add more ones to the current ones: .
Step 3: Regroup the ones into tens and ones: - Since is equal to one ten, the ones become , and the tens increase by .
Step 4: Calculate the new total number of blocks: - The original tens plus the additional ten from regrouping gives us tens. - Therefore, we now have blocks in total.
Thus, the new total number of blocks is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
You absolutely can! The blocks help you visualize what's happening with place value. Both methods give the same answer - blocks just show why regrouping works.
Same process! If you get 15 ones total, that becomes 1 ten and 5 ones. If you get 23 ones, that's 2 tens and 3 ones. Always group every 10 ones into 1 ten.
No! Only when your ones add up to 10 or more. If 3 ones + 4 ones = 7 ones, no regrouping needed since 7 is less than 10.
Count tens first: each ten block = 10. Then add any leftover ones. So 4 tens + 0 ones = blocks total.
Always trust the numbers stated in the problem first. The picture is there to help visualize, but focus on what the problem tells you: 35 blocks = 3 tens + 5 ones.
