Numbers & Operations in Base 10

4th Grade students will be able to:

• Demonstrate an understanding that in a multi-digit whole number (through 1,000,000), a digit in one place represents ten times what it represents in the place to its right. 

  • Example: Recognize that in the number 770, the 7 in the hundreds place is ten times the 7 in the tens place. 

• Read and write whole numbers in expanded, standard, and word form through 1,000,000. 

• Compare two multi-digit numbers through 1,000,000 based on meanings of the digits in each place, using >, =, and < symbols. 

• Round multi-digit whole numbers (through 1,000,000) to any place.

• Add and subtract multi-digit whole numbers (limit sums and subtrahends up to and including 1,000,000). 

• Multiply a whole number of up to four digits by a one-digit whole number and multiply 2 two-digit numbers. 

• Divide up to four-digit dividends by one-digit divisors with answers written as whole-number quotients and remainders. 

• Estimate the answer to addition, subtraction, and multiplication problems using whole numbers through six digits (for multiplication, no more than 2 digits × 1 digit, excluding powers of 10).
