7th Grade Math Samples and Populations in a PowerPoint Presentation
This slideshow lesson is very animated with a flow-through technique. I developed the lesson for my 7th grade class, Pre-Pre-Algebra, but it can also be used for upper level class reviews. This lesson teaches how to determine when samples are representative of populations and use data from random samples to make predictions about populations.
This lesson has SKELETON NOTES, notes that have the problem only. I used this with our 1-1 district devices. This will allow for the students to follow the lesson easier. There are 6 slides per page with plenty of room for notetaking. They are in a pdf format for easy printing too. A Word document is included for you to EDIT if you won’t be doing all of the problems so you can shorten it. I also made that is only one or two sheets long in a pdf. When I printed off skeleton notes for the whole class this is what I used. It is also editable so you can delete the problems and rearrange the skeleton notes however you want.
: The lesson is in an editable format so you can tailor the lesson to your class. The due to the TOU and to maintain the copyright integrity of the product. If you need an alternative version because your country uses different measurements, units, or slight wording adjustment for language differences just email me at PrestonPowerPoints@gmail.com. I am respond to email quickly.
The presentation has 35 slides with LOTS of whiteboard practice. Use as many or as few of the problems to help your students learn each concept. For more PowerPoint lessons & materials visit Preston PowerPoints.
Students often get lost in multi-step math problems. This PowerPoint lesson is unique because it uses a flow-through technique, guided animation, that helps to eliminate confusion and guides the student through the problem. The lesson highlights each step of the problem as the teacher is discussing it, and then animates it to the next step within the lesson. Every step of every problem is shown, even the minor or seemingly insignificant steps. A helpful color-coding technique engages the students and guides them through the problem (Green is for the answer, red for wrong or canceled numbers, & blue, purple & sometimes orange for focusing the next step or separating things.) Twice as many examples are provided, compared to a standard textbook. All lessons have a real-world example to aid the students in visualizing a practical application of the concept.
This lesson applies to the Common Core Standard:
Statistics & Probability 7.SP
Use random sampling to draw inferences about a population.
1. Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.
2. Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data. Gauge how far off the estimate or prediction might be.
