This lesson describes the difference between algebra and arithmetic, variables and constants. It introduces algebraic notation, and the concept of balancing equations. It discusses simplifying expressions and evaluation expressions. In the second half, it discusses methods for solving basic equations - first one variable, one step the multi-steps. It would be best taught over at least 2 lessons of 55-60 minutes each.

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 contains 8 weeks of lessons, which were given to my Gifted 5th grade math class. It may be appropriate for 6th grade non-gifted classes. Topics include: Order of Operations Powers of 10 Metric System, converting Metric units Exponents with Powers of 10 Scientific Notation - both small and larger numbers Intro to Pre-Algebra and Variables Slides are highly animated, showing step-by-step how to solve equations.

Basic geometry including definitions (points, lines, planes, rays, etc.), shapes, types of angles and triangles, perimeter, area and volume including irregular shapes. Difference between 2D and 3D shapes. Slides are annotated, showing step-by-step how to solve equations. Includes a quiz at the end. 4th grade level or advanced 3rd graders. I also have a more advanced version for 5th-6th.

Covers the basics of fractions - terminology, proper, improper, and mixed numbers. Shows how to find a common denominator, add and subtract fractions, then multiply and divide fractions. The concepts of reciprocals is introduced and how to use reciprocals to divide fractions. Slides are animated and show how to solve equations step-by-step when in presentation mode. Concludes with very brief intro to how decimals compare to fractions.

This presentation contains an introduction to negative numbers, the number line, absolute value, and then the rules for adding, subtracting, multiplying and dividing with negative numbers. There are word problems at the end with one advanced challenge problem. It is appropriate for 5th to 6th graders, or 7th graders needing a review. This can be taught over 2-3 classes. Approximately 2 hours 15 minutes to 2 hours 30 minutes teaching time, plus time for questions, introductions, etc. To avoid ru

This material will take 5-6 days with 50-55 minute lessons per day. Recommended level is 6th-7th grade, although advanced 5th graders will typically do well. Perimeter, area and volume should be review but there is advanced material on the triangle sum theorem, finding missing angles, calculating area and volume of irregular shapes, trapezoids, circles and spheres. Also introduces pi and relationship between circumference, radius and diameter. Slides are animated, showing how problems are solved

Full quarter of 6th grade level math lessons including integers, the coordinate plane and graphing, geometry including 2D and 3D, circles and spheres

This 91-slide lesson helps students to gain a strong foundation for the concepts of multiplication and division before exploring what it means to multiple and divide with fractions. We explore on a number line problems such as "3 divided by 1/4". Slides are animated, showing step-by-step solutions.

Presentation covering the basics of multiplication and division, then some mental math strategies for multiplying 12's, 15's, 20's, and numbers ending in zero(s). Next, it walks through step-by-step with animation how to multiply multi-digit numbers with carrying. It also covers long division with the family style method. Several word problems at the end. 4th to 5th grade level or advanced 3rd.

This 42- slide lesson/Powerpoint lecture on graphing with the coordinate plane includes slope, intercept, linear equations and other pre-algebra topics. It is highly animated, showing step-by-step how to perform calculations. Main topics include: Definition of line and linear equation with examples Identifying sign of slope Calculating slope Special cases - no slope and undefined slope Slope-intercept form - what it is and how to write equations in this form This would be appropriate for 6th gr

This math lesson covers equivalent fractions; adding, subtracting, multiplying and dividing fractions; reciprocals, improper fractions and mixed numbers. Slides are animated showing the method of solving problems step-by-step. Includes word problems. Teaching time approx. 60-80 minutes not including questions. Ideally would be taught over 2 lessons or around 40 minutes each.

5 worksheets on integers, each with their own solutions key Topics - Add, Subtract, Multiply, Divide & Absolute Value 14 total pages Includes some variable expressions

This presentation covers English and Metric units of measure (plus some other weird units!), a brief history of measurement, how to convert between metric units, the three temperature scales and how to convert between them, plus the difference between time shown on clocks. This would be best covered over 2 lessons of around 45-50 minutes each. Some of the younger students find the conversions to be difficult and may require a bit of extra time for those.
