54 slide presentation covering theory and examples of exponents, exponential notation, and scientific notation including back and forth conversions between exponential and standard notation, scientific and standard notation. Introductory level, would be appropriate for advanced 6th graders to 8th grades. Slides are animated with many examples solved.

This 41-slide presentation includes the following topics: The Normal Distribution Standardizing Data with Z Scores Z Tables and Standard Deviations from the Mean Central Limit Theorem Slides are highly animated, showing solutions step-by-step.

Lesson on converting between fractions, decimals and percentages, percent increase or decrease, percent of a number, ratios and proportions. Emphasis on what percentage actually means. I taught this over 5 days, 50-55 minute lessons per day. Target level 5th-6th grade, or 7th grade as review. This would ideally be spread out over several weeks. Slides are annotated, showing step-by-step how to solve problems. Includes work problems and practical examples. I have a shorter, simpler version geared

This presentation covers a brief review of long division, with emphasis on understanding why we do long division and why it works. Then it covers division of a decimal number by a whole number, and finally, division with decimals in the dividend and divisor. It includes a review of decimal place value names, and cancelling zeros when dividing. It covers rounding of decimal numbers. It concludes with several word problems. Slides are animated to show step-by-step solutions. I taught this material

Lesson on interpreting bar graphs. 25 slides with multiple choice questions asking students to interpret the difference between lines on bar graph. Would be appropriate for 4th to 5th grade. Slides are animated and include colorful pictures and graphics.

This presentation covers adding and subtracting rational expressions with variable and unlike denominators. It covers finding a like denominator when the denominator is a variable expression, and then performing the addition or subtraction. Slides are highly animated, showing each step of solving the equations.

Review presentation covering full AP Statistics Course. 110 slides covering approximately 50 problems, with questions, answers, steps, and a few some mini-reviews thrown in. Some questions are conceptual but most involve calculations. Presentation is highly animated with formulas coming in to show steps. Also includes Z-tables and interpretation.
