4.NBT. Grade 4 - Number and Operations in Base Ten

4.NBT.A. Generalize place value understanding for multi-digit whole numbers.

• What's My Number?

4.NBT.A.1. Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that $700 \div 70 = 10$ by applying concepts of place value and division.

• Thousands and Millions of Fourth Graders
• Threatened and Endangered

4.NBT.A.2. Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using $>$, =, and $<$ symbols to record the results of comparisons.

• Ordering 4-digit numbers

4.NBT.A.3. Use place value understanding to round multi-digit whole numbers to any place.

• Rounding on the Number Line
• Rounding to the Nearest 1000
• Rounding to the Nearest 100 and 1000

4.NBT.B. Use place value understanding and properties of operations to perform multi-digit arithmetic.

• To regroup or not to regroup

4.NBT.B.4. Fluently add and subtract multi-digit whole numbers using the standard algorithm.

• No tasks yet illustrate this standard.

4.NBT.B.5. Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

• Thousands and Millions of Fourth Graders

4.NBT.B.6. Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
