Grade 7 Math: Probability, Percent, and Rational Number Equivalence — Flashcards
| Front | Back |
|---|---|
| What is probability? | A number between 0 and 1 that expresses the likelihood of a chance event occurring; larger numbers indicate greater likelihood. |
| What does a probability near 0 indicate? | An unlikely event. |
| What does a probability near 1 indicate? | A likely event. |
| What does a probability around ½ indicate? | An event that is neither unlikely nor likely. |
| What is theoretical probability? | The probability calculated based on the possible outcomes in a sample space, without conducting an experiment. |
| What is experimental probability? | The probability estimated by collecting data on a chance process and observing its long-run relative frequency. |
| What is chance? | The likelihood that a particular event will occur. |
| What is frequency? | The number of times a particular outcome occurs in a data set or experiment. |
| What is an outcome? | A possible result of a chance process or experiment. |
| What is a ratio? | A comparison of two quantities; in this chapter, focus is on part:whole ratios (as opposed to part:part). |
| What is a fraction (in this context)? | A part:whole relationship representing a portion of a whole, related to decimals and percents. |
| What is a decimal? | A rational number form that can be found by dividing the numerator by the denominator of a fraction using long division; terminates in 0s or eventually repeats. |
| What is a percent? | A ratio comparing a number to 100, representing a part:whole relationship. |
| 7.NS.2d | Convert a rational number to a decimal using long division; know that the decimal form terminates in 0s or eventually repeats. |
| 7.NS.3 | Solve real-world and mathematical problems involving the four operations with rational numbers. |
| 7.SP.5 | Understand that probability of a chance event is a number between 0 and 1 expressing likelihood of occurrence. |
| 7.SP.6 | Approximate probability of a chance event by collecting data on the process and observing long-run relative frequency; predict relative frequency given the probability. |
| 7.EE.3 | Solve multi-step real-life and mathematical problems with positive and negative rational numbers in any form, converting between forms as appropriate and checking reasonableness of answers. |
| Why does Chapter 1 begin with probability? | To review/apply arithmetic with whole numbers and fractions, and to help foster a classroom culture of discussion, collaboration, and investigating real-world situations. |
| What relationship do fractions, decimals, and percents share? | They are all relative to a whole (part:whole relationships) and can be converted between one another. |
| What is the difference between part:whole and part:part relationships? | Part:whole relationships (like probability, fractions, decimals, percents) compare a part to the whole; part:part relationships (like "odds," studied in Chapter 4) compare one part to another part. |
