## Calculus Textbook Evaluations

Look for the following material or heading in the contents.

• Limits and Derivatives
· Limit of a function
· Calculating limits
· Limit laws
· Continuity
• Differentiation Rules
· Rates of change
· Derivative rules (polynomials and exponentials)
· Product rule
· Quotient rule
· Derivatives of trigonometric functions
· The chain rule
· Implicit differentiation
· Derivatives of logarithmic functions
• Applications of Differentiation (subtitles may differ widely here)

Notes for use: This course should be equivalent to a Calculus One course at a local university. If you know what school your child plans to attend, find out which textbook they use and go with it. In fact, ask for a syllabus and sample tests. A good deal of information can be gleaned from the UAB website on the screening test and the UAB test bank. (See the resources at the end of the chapter.)

Also, note that these books are often written for Calculus I, II, and III. So your text will be a lot bigger than what you will teach in high school. Also, if you do go with a college textbook you will pay a hefty price. An alternative is to find the previous edition on eBay – much cheaper with probably little change in material.

## Geometry Textbook Evaluations

Look for the following material or heading in the contents.

• Reasoning and Proof
· Proofs
· Deductive reasoning
· Direct and indirect proofs
• Lines
· Parallel and Perpendicular Lines
· Angles
• Triangles
· Congruent
· Isosceles
· Equilateral
· ASA and SAS
· Parallelograms
· Rectangles
· Squares
· Trapezoids
• Area
· Squares
· Rectangles
· Triangles
• Similarity
· Ratio and proportion
· Similar figures
• Right Triangle Trigonometry
· Pythagorean Theorem
· Proportions
· Tangent, Sine, and Cosine
• Surface Area and Volume
· Geometric solids
· Rectangular solids
· Spheres
• Circles
· Chords
· Tangents
• Transformations
· Reflections

Notes for use: One of the keys of geometry is learning deductive reasoning or how to do proofs. This can be a challenge to teach, so getting a teachers manual will really help here. The second main idea of geometry is getting used to thinking in space with shapes and the relationships between them. Lots of figures should be drawn.

## Algebra Textbook Evaluations

Look for the following material or heading in the contents.

• Variables
• Exponents
• Order of Operations
• Equations and inequalities
• Word problems (converting words into symbols)
• Real Numbers
• Subtracting
• Multiplication
• Division
• Distributive property
• Linear Equations (might be equations in one variable)
• Graphing

Notes for use: All the material on the above list needs to be covered in algebra. Instead of moving fast, the students should understand these concepts pretty well.

## How to Evaluate Math Textbooks and Material

Steps to evaluate a math textbook:

1. Make sure the basic material is covered. Look at the outlines below as a guide. The wording and chapter arrangement may be different, but you should see these key ideas in the contents.
3. Since you will be using the material for homeschooling, look for material with lots of worked examples. Go through some yourself and determine if they are easy to read and follow.
4. Look for plenty of problems to work.
5. Do you have the answers? We like the textbooks that have the answers to the odd-numbered problems for the students and then have the solutions to all the problems in the teacher’s manual. If they do not have the answers to many problems, your students will never know if they are doing the problems correctly.
6. Look for some real-world examples and problems. Do the problems tell about real situations? This is key to helping your child see the use of the material.
7. Look at some chapters. Are the key points of the chapter outlined in boxes or color so that they stand out? This makes it easy to use as a reference now and later.
8. Is there a teacher’s reference that tells you how to use the book? If so, is it useful to you? Does it make sense to you?
9. Is there an index?
10. What does your student think? If you can, let them compare a few and ask which they like better.

Math materials (such as textbooks, videos, or computer-based teaching) should all cover the same material per course title. In fact, many textbooks will have the exact same chapter titles. So you can do a pretty good job evaluating the coverage of material based on the chapter and subchapter titles. Here are some typical titles or subtitles that should be keywords in your comparison of material. Note that these topics may not match your textbook exactly or be in the same order as listed below. But, a majority of the key points listed should be found.

To use this guide go to the table of contents and look for these keywords. You should not have to search the entire text or videos to find them.

## Can my son/daughter do this course on their own without my help?

Yes. We know, we homeschool too. Parent overload is common. We have designed all of our courses so that you can either do it with them or have them do it on their own.

At our home we teach our children to do everything on their own. We help them plan out a schedule for the term at first using the syllabus. Then each week we review progress. They work on their own except when they have questions, need group interaction, or need to have a test graded.

Our view is that we are preparing our kids for college and life, and we want to teach them to learn on their own, to have a love for learning, and to develop personal responsibility.

## TI Calculator Emulators

Texas Instruments (TI) are our calculators of choice. There are many other great companies – so this is a personal preference.

• Algebra, Geometry, Biology, Chemistry  – For these courses, the TI-30 Scientific Calculator is perfect. It is inexpensive and does all you need.
• Algebra 2 with Trig, Calculus, Physics, Statistics, and beyond – These courses require a bit more horsepower as well as some graphical tools. Our choice is the TI-84 Plus CE.

Note: The TI-84 Plus CE is approved for use on the following exams: PSAT, SAT, and ACT college entrance exams and AP Exams that allow or require a graphing calculator.

Web Base Calculators

Scientists and engineers are using more powerful tools today. One such tool that is free to use is Wolfram Alpha. It has APPS and extensions for web browsers etc. If you ask us a question on support, this is the tool we use. But, you cannot take it into the ACT/SAT or other tests – so you need to be able to use your calculator also.

Emulators

Emulators are software programs that operate like the calculator. For the TI graphing calculators you can find some here. You may find others by searching You can also find some apps for these and even so a search “TI Emulators”
