 * Targets:**
 * 1) Define, classify, compare, and order rational and irrational numbers. Place rational and irrational numbers on a number line.
 * 2) Evaluate and simplify expressions, including formulas, containing rational numbers and square roots using the order of operations.
 * 3) Simplify, add, subtract, multiply, and divide expressions with square roots.
 * 4) Compute solutions to real world problems, representing my answer in exact form, determining whether or not my answer is reasonable using estimation.
 * 5) Use the Pythagorean Theorem to find any missing side of a right triangle.

Rational and Irrational Numbers Five quick activities for ordering, comparing, and classifying real numbers.[| A Question of Order (Alg 8.6 Revised).doc] Students develop an understanding of square roots using geometric representations.[| Squares and Square Roots Simple (Alg 8.5 Revised).doc] Practice worksheet on placing rational numbers on a number line and ordering the numbers from least to greatest. Practice worksheet on perfect squares.[| Perfect Squares.pdf] Practice worksheet on classifying rational and irrational numbers.[| ClassifyRationalIrrational.pdf] Practice worksheet on ordering real numbers (between two integers, number line).[| Ordering Real Numbers.pdf]

In this lesson, students estimate the square roots of non-perfect squares using perfect squares. Then they give the approximate location of the non-perfect squares on a number line.
