3rd Grade Algebra and Functions:  Standards and Practice Problem(s)	VoiceThread Mathcasts
3AF.1.0 Students select appropriate symbols, operations, and properties to represent, describe, simplify, and solve simple number relationships:
3AF.1.1 Represent relationships of quantities in the form of mathematical expressions, equations, or inequalities.	View full-sized 3AF1-1 Ready
3AF.1.2 Solve problems involving numeric equations or inequalities.	3AF1-2 Ready
3AF.1.3 Select appropriate operational and relational symbols to make an expression true (e.g., if 4 __ 3 = 12, what operational symbol goes in the blank?).	3AF1-3 Ready
3AF.1.4 Express simple unit conversions in symbolic form (e.g., __ inches = __ feet x 12).	3AF1-4 Ready
3AF.1.5 Recognize and use the commutative and associative properties of multiplication (e.g., if 5 x 7 = 35, then what is 7 x 5? and if 5 x 7 x 3 = 105, then what is 7 x 3 x 5?).	3AF1-5 Ready
3AF.2.0 Students represent simple functional relationships
3AF.2.1 Solve simple problems involving a functional relationship between two quantities (e.g., find the total cost of multiple items given the cost per unit).	3AF2-1 Ready
3AF.2.2 Extend and recognize a linear pattern by its rules (e.g., the number of legs on a given number of horses may be calculated by counting by 4s or by multiplying the number of horses by 4).	3AF2-2 Ready
