Study Notes

Comparing Numbers

  • Methods: Comparing 3-digit numbers using > (greater than), < (less than), or = (equal to).
  • Ordering: Arranging numbers in ascending (least to greatest) or descending (greatest to least) order.
  • Expanded Form: Identifying the place value of digits (ones, tens, hundreds) in a number.
  • Example: 300 + 50 + 6 is equivalent to 356.
  • Example: 7 hundreds, 3 tens, 3 ones is 733.

Ordering Numbers

  • Ascending Order: Arranging numbers from smallest to largest.
  • Descending Order: Arranging numbers from largest to smallest.
  • Example: Ordering numbers like 352, 637, 471, 564 in ascending order results in 352, 471, 564, 637.

Finding Greatest and Least Numbers

  • Determining greatest and least numbers: Finding the largest and smallest possible numbers that can be made using the provided digits.
