Grade 8 - Number Sense and Numeration

Standard 8.NSN.1 - Practice solving scientific notation inequalities by finding the symbol that makes the equation true.

Included Skills:

Quantity Relationships

• express repeated multiplication using exponential notation (e.g., 2 x 2 x 2 x 2 = 2 to the 4th power);

• represent whole numbers in expanded form using powers of ten (e.g., 347 = 3 x 102 + 4 x 10 to the 1st power + 7);

• represent, compare, and order rational numbers (i.e., positive and negative fractions and decimals to thousandths);

• translate between equivalent forms of a number (i.e., decimals, fractions, percents) (e.g., 3/4 = 0.75);

• determine common factors and common multiples using the prime factorization of numbers (e.g., the prime factorization of 12 is 2 x 2 x 3; the prime factorization of 18 is 2 x 3 x 3; the greatest common factor of 12 and 18 is 2 x 3 or 6; the least common multiple of 12 and 18 is 2 x 2 x 3 x 3 or 36).
