Unit 1

UNIT OVERVIEW - In this unit students will learn to:

• Use units of measure (linear, area, capacity, rates, and time) as a way to understand problems.

• Interpret units in the context of the problem.

• Convert units and rates using dimensional analysis (English–to–English and Metric–to– Metric without conversion factor provided and between English and Metric with conversion factor).

• Identify the different parts of the expression or formula and explain their meaning.

• Operate with polynomials with an emphasis on expressions that simplify to linear or quadratic forms.

• Rewrite (simplify) expressions involving radicals.

• Use and explain properties of rational and irrational numbers.

• Explain why the sum or product of rational numbers is rational; why the sum of a rational number and an irrational number is irrational; and why the product of a nonzero rational number and an irrational number is irrational.
