Type: Audio/Video

Overview:

In this video segment from Cyberchase, the CyberSquad is shooting a film. On their fourth day of filming, they hope to shoot an extra scene, which means their film supply costs will go up. They look at their budget and find that if they lower their crew costs, they can film the extra scene without going over their budget for the day. The crew uses their multiplication and division skills to budget the extra scene.

Content Standard(s):
Mathematics
MA2019 (2019)
Grade: 3
5. Develop and apply properties of operations as strategies to multiply and divide.
(Students need not use formal terms for the properties)

Unpacked Content
Evidence Of Student Attainment:
Students:
  • Use their understanding of multiplication and division to develop and apply a variety of properties to various situations.

    • Examples: given 4 x 9 = 36 is known, then 9 x 4 = 36 is also known. (commutative property). If 3 x 5 x 2 can be found by 3 x 5 =15, then 15 x 2 = 30 or 5 x 2 = 10, then 3 x 10 = 30. (associative property). If 8 x 5 = 40 and 8 x 2 = 16 are known, then 8 x 7 can be found by 8 x (5 + 2) = (8 x 5) + (8 x 2) = 40 + 16 = 56. (distributive property.)
  • Identify an equivalent expression where the properties of operations has been applied.
  • Describe the properties of multiplication related to visual models.
  • Write multiplication equations to represent visual models.
  • Apply properties of operations as strategies to multiply and divide.
Note: Students need not use formal terms for the properties of operations.
Teacher Vocabulary:
  • Product
  • Sum
  • Property of operations
  • Multiplication expression
  • Decompose
  • Array
  • Area model
Knowledge:
Students know:
  • When any factor, x, is multiplied by a factor of 1, the product is the value of x.
  • If one factor is zero, then there are zero groups or zero items in a group and the product is zero.
  • The commutative property of multiplication shows a x b = c and b x a = c.
  • The associative property of multiplication shows that when multiplying three or more numbers, the product is always the same regardless of the grouping.
  • The distributive property will help in finding products of more difficult multiplication facts.
Skills:
Students are able to:
  • Develop properties as strategies for multiplication and division.
  • Apply properties of operations as strategies to multiply and divide.
Understanding:
Students understand that:
  • applying properties of operations can help develop strategies to find solutions to multiplication and division problems.
Diverse Learning Needs:
Essential Skills:
Learning Objectives:
M.3.5.1: Define properties of operations.
M.3.5.2: Apply basic multiplication facts.
M.3.5.3: Apply properties of operations as strategies to add and subtract.

Evidence Of Student Attainment:
Students:
  • When given any single digit multiplication problem, use an efficient strategy (recall, inverse operations, arrays, derived facts, properties of operations, doubling, skip counting, square numbers) to name the product.
  • When given a division problem with a single digit divisor and an unknown single digit quotient, use an efficient strategy (recall, inverse operations, arrays, derived facts, properties of operations, doubling, skip counting, square numbers) to name the quotient.
Teacher Vocabulary:
  • Fluently
