Unit 3: Number

Analyzing puzzles and games that involve logical reasoning, and critiquing the viability of small-business options by weighing expenses, sales, and profit or loss.

• Finding a logical strategy in a puzzle or game
• Justifying a logical strategy

• Expenses, sales, and profit or loss
• Break-even and critiquing viability
• Comparing small-business options

Unit 4: Algebra

Understanding linear relations by recognizing patterns and trends, graphing, creating tables of values, writing equations, and interpolating and extrapolating to solve problems.

• Patterns, trends, and tables of values
• Graphing a linear relation
• Writing the equation of a linear relation
• Interpolating, extrapolating, and solving problems

Unit 5: Statistics

Solving problems with measures of central tendency (mean, median, mode, weighted mean, trimmed mean) and analyzing and describing percentiles.

• Mean, median, and mode
• Weighted mean and trimmed mean
