1.3 Properties of Numbers

Standard(s):

1.OA.B3:

  • Understand and apply properties of operations and the relationship between addition and subtraction.
  • Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)

3.OA.B5:

  • Understand properties of multiplication and the relationship between multiplication and division.  
  • Apply properties of operations as strategies to multiply and divide.  Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.)



Essential Questions:

  • How can the properties of the real number system be used?
  • How can properties of algebra be used to describe the relationship between sets of numbers?


Learning Targets:

  • I can identify the property used. (Knowledge)
  • I can apply properties. (Application)
  • I can demonstrate the concept of equality. (Comprehension)
