14.4 Geometric Patterns (p. 319-321)

I. Fractal: an endlessly repeating pattern that looks like the whole, but different sizes
II. Iteration: a step in the process of making a fractal that follows a pattern

14.3 Number and Pattern Functions (p. 315-318)

I. Function: relationship between two quantities in which one quantity depends uniquely on the other every input has one output
II. Use an equation, function table, or function machine

14.2 Patterns in Sequence (p. 312-314)

I. Sequence: an ordered set of numbers - each number in the sequence is called a term
II. If you can find a rule, it can be used to find any number in a sequence
III. Figure out if the values are increasing or decreasing

14.1 Problem Solving: Find a Strategy (p. 310-311)

I. Ways to find patterns
A. Make a table
B. Figure out the relationship between consecutive numbers
C. Find the difference between consecutive numbers

13.5 Inequalities (p.300-303)

I. An inequality is an algebraic sentence that contains the symbol <, >, ≤, ≥, or ≠ because the sides are not equal
II. An inequality can sometimes be solved the same way as an equation
III. When graphing on a number line
A. <> Use an open circle if the value at that spot is not included in the solution
B. ≤ or ≥ Use a filled in circle if the value at that spot is a possible solution
IV. If you multiply both sides of an inequality by a negative number it will reverse the direction of the inequality sign

13.4 Problem Solving: Work Backwards (p.298-299)

13.4 Problem Solving: Work Backwards (p. 298-299)
I. Use when the problem describes a series of actions and tells the result
II. Can be used to solve a problem represented by an equation by undoing the operation
III. When a desired outcome is known, work backwards to figure out what you need to do to make it work
