  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
• What is the purpose of the PLACE VALUE CHART?


  • To show the value of each digit in a number
  • Organizes digits into THOUSANDS, HUNDREDS, TENS, and ONES
• What is the place value of the digit 8 in the number 5648?


  Ones
• How do you calculate the value of the digit 4 in the number 5648?

  Sum
• What does the word "in all" indicate in a math problem?


  That you should add the numbers
• How do you align numbers when adding whole numbers?


  By aligning the last digits above each other
• What is the Commutative Property of Addition?


  The order of the addends does not affect the sum
• What does the Associative Property of Addition state?


  Changing the grouping of the addends does not affect the sum
• What is the Identity Property of Addition?


  The sum of a number and zero is the same number
• What is the process of subtraction?

  The grouping of the factors does not affect the product
• What is the Identity Property of Multiplication?


  When a number is multiplied by 1, the product is the number itself
• What is the Zero Property of Multiplication?


  Any number multiplied by zero is zero
• What is division as repeated subtraction?


  Subtracting a number repeatedly until reaching zero
