8th Grade Math (Pre-Algebra) Finding Cube Roots in a PowerPoint Presentation
This slideshow lesson is very animated with a flow-through technique. I developed the lesson for my 8th grade class, but it can also be used for upper level class reviews. This lesson teaches how to find cube roots of perfect cubes, evaluate expressions involving cube roots, use cube roots to solve equations, and solve a real-life problem by using cube roots to find the length of a life size number cube.
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.
The presentation has 43 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:
Expressions and Equations 8.EE
Expressions and Equations Work with radicals and integer exponents.
2. Use square root and cube root symbols to represent solutions to equations of the form x2 = p and x3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.
Please note that these PowerPoints are NOT EDITABLE
. They WILL NOT
work with Google Slides or Adobe Connect. You will need the PowerPoint software.
If you need an alternative version because your country uses different measurements, units, slight wording adjustment for language differences, or a slide reordering just ask.
