Lesson 1: The Areas of Squares and Their Side Lengths
-
I can find the area of a triangle.
-
I can find the area of a tilted square on a grid by using methods like “decompose and rearrange” and “surround and subtract.”
Lesson 2: Side Lengths and Areas
-
I understand the meaning of expressions like $\sqrt{25}$ and $\sqrt{3}$.
-
If I know the area of a square, I can express its side length using square root notation.
-
I can explain what a square root is.
Lesson 3: Rational and Irrational Numbers
-
I know what an irrational number is and can give an example.
-
I know what a rational number is and can give an example.
Lesson 4: Square Roots on the Number Line
-
I can find a decimal approximation for square roots.
-
I can plot square roots on the number line.
Lesson 5: Reasoning About Square Roots
-
When I have a square root, I can reason about which two whole numbers it is between.
Lesson 6: Finding Side Lengths of Triangles
-
I can explain what the Pythagorean Theorem says.
Lesson 7: A Proof of the Pythagorean Theorem
-
I can explain why the Pythagorean Theorem is true.
Lesson 8: Finding Unknown Side Lengths
-
When I have a right triangle, I can identify which side is the hypotenuse and which sides are the legs.
-
If I know the lengths of two sides, I can find the length of the third side in a right triangle.
Lesson 9: The Converse
-
I can explain why it is true that if the side lengths of a triangle satisfy the equation $a^2+b^2=c^2$ then it must be a right triangle.
-
If I know the side lengths of a triangle, I can determine if it is a right triangle or not.

-
I understand the meaning of expressions like $\sqrt[3]{5}$.
-
I can approximate cube roots.
Lesson 13: Cube Roots
-
When I have a cube root, I can reason about which two whole numbers it is between.

-
I understand that every number has a decimal expansion.
-
I can write a fraction as a repeating decimal.
