7th Grade Math Ratios and Rates 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 find ratios, rates and unit rates and find ratios and rates involving ratios of fractions.
This lesson has SKELETON NOTES, notes that have the problem only. This will allow for the students to follow the lesson easier. There are 6 slides per page. They are in a pdf form for easy printing. I also attached the Word document for you to EDIT. If you won’t be doing all of the problems you can shorten what you print off for the skeleton notes.
NEW: The lesson is in an editable format so you can tailor the lesson to your class. The problems and clipart can’t be edited 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 38 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:
Ratios & Proportional Relationships 7.RP
Analyze proportional relationships and use them to solve real-world and mathematical problems.
1. Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.
3. Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
