A math educator once asked his daughter, who was in Algebra 1, if she knew what slope was. She said yes. He asked her what it was. She replied that it is the m in y = mx + b. When asked to elaborate, she could only go back to equations and rules. She got an A in algebra from her teacher. MA.6.A.3.2 Write, solve, and graph one- and two- step linear equations and inequalities.
3
Review… How would we graph a line without technology? y= x x y How about with technology?
4
y = x y= 2x y= 3x y= - 2x y= x y = mx+ b
5
Slope y = mx+ b Positive slope Negative slope
6
y = x + 2 y = x + 5 y = x - 4 y = x + y = mx+ b
7
y-intercept y = mx+ b Positive intercept Negative intercept
8
y = - 3x + 8

Grade 6: Big Idea : Develop an understanding of and fluency with multiplication of division of fractions and decimals Benchmark: MA.6.A.1.1 – Explain and justify procedures for multiplying and dividing fractions and decimals. Power Point Presentations
10
Students should have addressed the following in prior grades: ◦ Grade 3 Big Idea 2 -- Develop an understanding of fractions and fraction equivalence Explored the meaning of fractions Grade 4 Big Idea 2 -- Develop an understanding of decimals, including the connection between fractions and decimals Includes using various models to represent fractions. Grade 5: Big Idea 2-- Developing an understanding and fluency with addition and subtraction of fractions explored fractions using a variety of models (e.g., length, set, area)
11
Students must be taught how to use the models or tools used as part of instruction Online Geoboard

WinPlot and TI-Screen Capture (as part of Word or PPP) Allows you to express mathematical representation as part of presentations or worksheets Screen Capture of TI CalculatorGraph created using WinPlot
40
Test Generating Software Every textbook publisher offers one Others commercially available as well Generate multiple versions of same test easily
41
Online access to mathematics resources Tutoring (e.g., Dr. Math) Mathematics Dictionaries with examples FCAT Explorer
42
Textbook Websites Usually have practice tests and/or quizzes Also have other resources tied directly to the text. Florida’s adopted Grade 6 texts Glencoe Glencoe Holt, Rinehart, & Winston Holt, Rinehart, & Winston McDougal Littell McDougal Littell Prentice Hall Prentice Hall
43
Is it important to use technology to teach mathematics? Why or why not? What are appropriate uses of technology? Inappropriate uses? What should you consider when deciding to use technology or not?
44
Technology is an essential tool for learning mathematics in the 21st century, and all schools must ensure that all their students have access to technology. Effective teachers maximize the potential of technology to develop students’ understanding, stimulate their interest, and increase their proficiency in mathematics. When technology is used strategically, it can provide access to mathematics for all students. Full position statement
45
Teacher productivity Producing Mathematically accurate representations Keeping and recording class information Student Support Example: Ask Dr. Math Textbook Websites Teaching and Learning
46
Allows the visualization of concepts difficult to show otherwise Allows the examination of multiple examples with ease Allows a focus on concepts rather than calculations Allows access to real-time data to make mathematics relevant to students ◦ (e.g., use of real world examples such as orange production in Florida for analysis) Allows student to make and test conjectures ◦ What happens when … Promotes student independence in mathematical problem-solving Reinforces mathematics learning
48
The CPALMS will: Increase access for all teachers to high quality information and resources aligned with the standards Support the delivery of teacher professional development Support teacher application of new content and pedagogical knowledge in the classroom
49
The CPALMS will include the following: Searchable database of standards and benchmarks Levels of cognitive complexity for each benchmark Mathematics and Science Course Descriptions Course builder tool for districts Electronic course approval system Online PD on the use of course descriptions
50
It will be launched during 2008-09 school year.
51
We’ve only touched the surface of what’s available. Don’t be afraid to learn from your student. Just like any tool, technology only helps when used correctly/appropriately.
