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 MA2015 (2016) Grade: 3 5 ) Apply properties of operations as strategies to multiply and divide. (Students need not use formal terms for these properties.) [3-OA5] Examples: If 6 x 4 = 24 is known, then 4 x 6 = 24 is also known. (Commutative property of multiplication)                   3 x 5 x 2 can be found by 3 x 5 = 15, then 15 x 2 = 30, or by 5 x 2 = 10, then 3 x 10 = 30. (Associative property of multiplication)                   Knowing that 8 x 5 = 40 and 8 x 2 = 16, one can find 8 x 7 as 8 x (5 + 2) = (8 x 5) + (8 x 2) = 40 + 16 = 56. (Distributive property) NAEP Framework NAEP Statement:: 8NPO3a: Perform computations with rational numbers. Mathematics MA2015 (2016) Grade: 3 7 ) Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 x 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers. [3-OA7] NAEP Framework NAEP Statement:: 4NPO3c: Divide whole numbers: Up to three digits by one digit with paper and pencil computation, or Up to five digits by two digits with use of calculator. NAEP Statement:: 8NPO3a: Perform computations with rational numbers. NAEP Statement:: 8NPO3d: Describe the effect of multiplying and dividing by numbers including the effect of multiplying or dividing a rational number by: Zero, or A number less than zero, or A number between zero and one, One, or A number greater than one. Alabama Alternate Achievement Standards AAS Standard: M.AAS.3.7- Multiply and divide one-digit numbers using repeated addition or repeated subtraction where the products are within twenty and the factors are one, two, three, four, five, or ten using multiplication and division tools.
