8th Grade Math (Pre-Algebra) Scale Drawings and Scale Models in a PowerPoint Presentation
This slideshow lesson is very animated with a flow-through technique. I developed the lesson for my Pre-Algebra class, but it can also be used for upper level class reviews. This lesson teaches how to understand ratios and proportions as it relates to scale factor. Also, use scale factor to find different size versions of an object.
The presentation has 28 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:
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.
