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 .
Add fifty units to the number 31.
What is the resulting number?
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.
