Multiplying and Dividing Real Numbers on a Number Line in a PowerPoint Presentation
This slideshow lesson is very animated with a flow-through technique. It was made for my Algebra 1 class, but can be used for lower grades. This lesson was one of a chapter that was used as a review for all previous grades. The lesson teaches how to multiply and divide real numbers using properties of multiplication and division in a number line.
The presentation has 83 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 that helps to eliminate confusion and guide 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. 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:
The Number System 7.NS.A
Apply and extend previous understandings of operations with fractions.
2a. Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts.
2b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then –(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real-world contexts.
Please note that the PowerPoint is not editable.
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.
