6. Similar figures

What does this word mean to you?

This word actually means….. figures with the same shape but not necessarily the same size (sides are proportional).

Examples… Explain how you would use this word in math.

Objective SPI 0706.1.2 Generalize a variety of

patterns to a symbolic rule from tables, graphs, or words.

Lesson Ch. 5 L 3 A function relates an input to an output.

It is like a machine that has an input and an output. And the output is related somehow to the input.

8. Directly Proportional

What does this word mean to you?

This word actually means…..a linear relationship between x and y, when graphed forms a linear line through zero : aka direct variation.

Examples… Explain how you would use this word in math.

Lesson Ch 5 L 4 Sequences- A Sequence is a list of things

(usually numbers) that are in order.

Two types Arithmetic Geometric

Arithmetic An arithmetic sequence goes from one term

to the next by always adding (or subtracting) the same value.

For instance 2, 5, 8, 11, 14, adds 3

 7, 3, –1, –5,. Subtracts 4

Geometric A geometric sequence goes from one term

to the next by always multiplying (or dividing) by the same value.

So 1, 2, 4, 8, 16, multiply by 2  

and 81, 27, 9, 3, 1, 1/3 divide by 3

9. Inversely Proportional

What does this word mean to you?

This word actually means…..a nonlinear relationship between x and y, when graphed forms a curved line and stays in one quadrant: aka inverse variation.

Examples… Explain how you would use this word in math.
