Algebra I Std. A.13 Rubric for Formative and Summative Assessment
	Excellent 4 pts	Good 3 pts	Fair 2 pts	Poor 1 pts
Estimating Square Roots Estimate the square root of a non-perfect square with examples. Find the square root to the furthest decimal place.	Excellent Procedure is correct and identifies the two perfect squares integers lay between, finding the square root of two perfect values to estimate the square root of the non-perfect square.	Good Procedure is correct but fails to complete ONE of these procedures: identifies the two perfect squares integers lay between, finding the square root of two perfect values to estimate the square root of the non-perfect square.	Fair Procedure is correct but fails to complete two or more of these procedures: identifies the two perfect squares integers lay between, finding the square root of two perfect values to estimate the square root of the non-perfect square.	Poor Neither the procedure nor examples given provides any evidence that the student understands the concept of estimating square roots.
Squaring and Square Roots Determine the relationship between squaring and square roots? Demonstrate with with examples.	Excellent Student describes the relationship as an inverse relationship. where t taking the square root of a number yields that number.	Good Student description recognizes that square roots and squaring are inverse operations. If the work inverse is not used, it is clear that the student understands the concept. The examples are correct.	Fair Student description demonstrates understanding that square roots and squaring are inverse operations, but is unable to show examples and explain relationship, but examples demonstrate some understanding.	Poor Neither the explanation nor the examples provide any evidence that the student understands the relationship between squaring and square roots.
Simplifying Radicals Simplify the radical expressions. Show your work to demonstrate knowledge of the concepts.	Excellent Student work shows that they identified perfect squares that could be factored out of the radicand. They demonstrate that understand that the square root of a product is the product of the square roots and simplify the expressions.	Good Student work shows most of the required work in identifying perfect squares that could be factored out of the radicand.	Fair Student work shows some of the required work in identifying perfect squares that could be factored out of the radicand.	Poor Work does not demonstrate an understanding of the process and properties used to simply radical expressions.
