8ns2 Worksheets

8ns2

• Decide which two whole numbers a square root falls between.
• Use nearby perfect squares to judge whether a square root is closer to the lower or higher whole number.
• Compare the sizes of different square roots by thinking about their values.

8ns2

• Recognize the perfect squares that are closest to a given square root.
• Decide which two whole numbers a square root falls between.
• Use nearby perfect squares to make a quick estimate of a square root’s size.

8ns2

• Place square roots on a number line by figuring out which two whole numbers they fall between.
• Estimate the decimal value of a square root well enough to plot it in the right spot.
• Use nearby perfect squares (like 16 and 25) to judge how close a square root is to a whole number.

8ns2

• Recognize perfect squares and perfect cubes so you can solve quickly without a calculator.

8ns2

• Break a number into factors and spot pairs that make a perfect square.
• Use exponents to write repeated factors more simply, like 3×3 as 3^2.

8ns2

• Practice rewriting square roots by pulling out perfect-square factors.
• Use factor pairs to break a number under a radical into simpler parts.
• Simplify radicals all the way to a number times a square root (like 3√2).
• Recognize which radicals are already in simplest form.

8ns2

• Practice estimating square roots of numbers that aren't perfect squares
• Figure out which two whole numbers a square root falls between
• Work with square roots of various sizes to build number sense around irrational numbers

8ns2

• Rewrite negative exponents as reciprocals so the exponent becomes positive.
• Evaluate expressions with negative powers to get the correct fraction or decimal value.
• Work with negative exponents on whole-number bases, fractions, and powers of 10.

8ns2

• Practice reading a number line that is divided into equal parts and understanding what each tick mark means.
• Learn to locate a decimal on a number line by using the interval between two whole numbers.
