Teacher Felicia Taylor Intensive Math 8 4 Real Numbers, Exponents & Scientific Notation
Standard(s) Taught

#### Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.

Learning Targets and Learning Criteria

I can…

• convert a rational number into a decimals.
• classify a number as a rational or irrational number based on whether the decimal form is repeating, terminating, or does not repeat or terminate.
• convert a repeating and terminating decimal into a rational number (fraction).
• estimate the value of an irrational number by rounding to a specific place value
• compare the size of two irrational numbers by using a number line.
• use reasoning to determine between which two consecutive whole numbers a square root will fall on a number line.
• recognize perfect squares and non-perfect squares and numbers that are perfect cubes.
• recognize taking a square root of a number as the inverse of squaring that number and taking a cube root of a number as the inverse of cubing that number.
• evaluate the square root of a perfect square and the cube root of a perfect square.
• justify that the square root of a non-perfect square will be irrational and that the cube root of a non-perfect cube will be irrational.
Classroom Activities

Tuesday

Continue working on missing assignments:

MathSpace

1. Fractions to Decimals
2. Rational and Irrationals

If either or both MathSpace assignments received a score of less than 70% the assigment was reassigned to the student(s) to redo.

IXL

1. D.4 Convert between decimals to fractions or mixed numbers
2. D.5 Identify rational and irrational numbers

Students are to continue working on D.4 & D.5 until a SmartScore of at least 70% is achieved.

Start the following IXL assignments:

1. D.6 Absolute value of rational numbers

Wednesday (Early Release Day – Short Class)

Continue working on assignments from Tuesday.

Friday

Continue working on IXL assignments until a SmartScore of at least 70% is achieved.

1. D.4 Convert between decimals to fractions or mixed numbers
2. D.5 Identify rational and irrational numbers
3. D.6 Absolute value of rational numbers

Start IXL assignments:

1. D.1 Write fractions in lowest terms
2. D.2 Least common denominator

Students are to continue working the IXL assignments until a SmartScore of at least 70% is achieved on each one.
