4nbt4
Add two four-digit numbers to find the total. Use carrying (regrouping) when a place value adds to 10 or more.
4nbt4
Subtract one 4-digit number from another accurately. Line up thousands, hundreds, tens, and ones so each digit is subtracted in the right place. Use borrowing (regrouping) when the top digit is smaller than the bottom digit in a place.
3nbt2
Subtract multi-digit numbers using borrowing when you need to trade from a higher place value. Handle subtraction problems where you have to regroup more than once in the same problem.
3nbt2
Practice adding multi-digit numbers using carrying when a place value adds to 10 or more. Practice subtracting multi-digit numbers using borrowing when you don’t have enough in a place value.
4nbt4
Subtract multi-digit numbers when you have to borrow across several zeros. Use regrouping to turn a zero in the top number into a number you can subtract from.
4nbt4
Add two 4-digit numbers written in a horizontal equation (e.g., 3,482 + 6,159). Regroup (carry) from ones to tens, tens to hundreds, and hundreds to thousands when adding 4-digit numbers. Use place value to add thousands, hundreds, tens, and ones accurately.
2nbt7 3nbt2
Practice adding and subtracting numbers up to 1,000 accurately. Decide whether to add or subtract based on the symbols in the problem. Use regrouping when needed to solve multi-digit addition and subtraction. Keep digits lined up by place value so the answer makes sense. Practice finding a missing number in addition and subtraction equations Get comfortable seeing the unknown in different spots — at the beginning, middle, or end of an equation
3nbt2
Subtract larger numbers where the top number has zeros in it. Use regrouping to subtract when you need to borrow across a zero. Line up digits by place value so each column is subtracted correctly.
3nbt2
Practice adding three numbers together to find a total Solve word problems by picking out the important numbers from a story Figure out when a problem is asking you to combine groups to find "how many in all"
4nbt4
Subtract numbers written in columns by lining up ones, tens, and hundreds correctly. Use borrowing (regrouping) when the top digit is smaller than the bottom digit in a place value.
3nbt2
Solve for an unknown number in simple addition and subtraction equations within 1,000. Use addition and subtraction facts to figure out what number makes an equation true. Check that the answer makes sense by plugging the number back into the equation.
2nbt5 4nbt4
Subtract two numbers when each top digit is big enough so you don’t need to borrow. Line up ones and tens correctly before subtracting. Subtract in vertical form, working from the ones place to the tens place.
3nbt2 4nbt4
Decide which operations are needed to solve a two-step word problem. Add and subtract multi-digit numbers accurately with regrouping. Find a missing part when the total and other parts are known. Check that an answer is reasonable using the context of the problem.
4nbt4
Solve for the missing number that makes an addition or subtraction equation true. Use the equals sign correctly by keeping both sides of an equation balanced. Add and subtract whole numbers to figure out an unknown value. Work through equations written in different mixed styles (like the blank on either side of the equals sign).
4nbt4
Practice adding two large numbers by breaking one number into place-value parts (thousands, hundreds, tens, ones) Use a number line to show each step of the addition as a separate jump Build up to the final sum by adding one place value at a time
4nbt4
Practice adding, multiply, subtracting and dividing the digits 6 and 7.
3nbt2 3oa8 4nbt4
Follow directions that require two steps in a row Carry the result of the first step into the second step Tell 'subtract 400 from it' apart from 'subtract it from 400' Add and subtract whole numbers up to 100,000
4nbt4
Use an open number line to subtract by making jumps back from the starting number. Break a subtraction problem into easier steps (like subtracting tens, then ones) and keep track of each jump. Explain your subtraction thinking by showing the jumps you made on the number line.
3nbt2
Learn how to set up subtraction problems in columns by lining up the ones, tens, and hundreds places. Practice subtracting multi-digit numbers using the traditional method. Use regrouping (borrowing) when the top digit is smaller than the bottom digit in a place value. Keep track of place value so each digit is subtracted from the correct digit.
4nbt4
Learn how to subtract using the traditional column method when the top number has one or more zeros. Practice borrowing (regrouping) across zeros so each place has enough to subtract. Keep digits lined up by place value so ones, tens, hundreds, and thousands are subtracted correctly. Write each step neatly and clearly so it’s easy to follow how the borrowing changed the numbers.
3nbt2 3oa8
Judge whether an answer someone else gave is reasonable Use estimation to check an answer without working it out exactly Recognize that one part can never be larger than the whole Decide when an answer is too far off to be believable
