Math

Math Foundation

Math is largely sequential and is very dependent on a firm knowledge of the items that come before it in studies. Consider the studies of Math as a series of interconnected stair steps where without a good support the upper treads fall off.

For example, it is hard to conceive of adding or subtracting if one does not know reliably how to count. It is impossible to really understand multiplication or division if one cannot add. While the concepts of algebraic abstraction can be explained to any first grader without fear; he or she could not really take advantage of the problem-solving capabilities if he or she cannot solve the underlying addition, subtraction, multiplication, or other numeric operation.

One tread that underlies math school work that is often overlooked, but extremely critical is handwriting skill. The student needs to be able to reliably form letters and numbers neatly so that they can be read by a grader or the student at a point in the future when the memory of the problem has faded. If the handwriting is messy and slips between lines, if the letters are indistinct and hard to read, if plus signs and negative signs are not consistently written then the answers will be wrong. If the figures that accompany the math are not done with a straight edge and compass, mistakes will be made.

On level? How can I tell?

If your child is not starting from the beginning then it is important to be sure that he has mastered all of the concepts. There are many options available to confirm how well or badly your child is doing in mathematics.
If your student is in a public school then you might be most comfortable measuring your student's progress against state and local metrics. Be aware that the state tests do not always test to ensure full mastery, but instead a minimal floor of mastery. To be confident in math as a student continues to later steps on a math journey, full mastery of each earlier step is much preferable!

On Level Checking with state testing

Some examples of state test materials that you can use to measure your child's level:
 Texas STAAR released tests
 Virginia's poorly abbreviated Standards of Learning (SOL) has released tests as well
 Alaska's Sample questions
 Washington State uses a program from Smarter Balanced Assessment Consortium to handle assessments

If you are entirely homeschooling and not supplementing, you might want to have your children take a full version of a test such as the Iowa assessments which can be ordered through  Bob Jones University testing.

On Level Checking with State or Local Curriculum Guides

Almost every school district has a curricula guide at the state or local level that discusses what will be taught in each class.
These guides tend to be worded to prevent any misunderstandings to people that already know what is being discussed which can make them annoying to read.
For example,
 Alabama's Math guideline
 Oklahoma Standards
Your neighborhood school might also have links to the local standards and coverage expected for each grade.

On Level Checking with Curriculum Placement Tests

There are a number of math providers for homeschool and classroom use that are familiar with having students transition between different curriculum programs and between brick and mortar schools and home and have assessments to help determine where the student fits. Even if you decide to pick a different program, working through a variety of assessments is useful to point out any gaps or holes in the student's knowledge.

 Saxon Math (Primary to Highschool)
 Math Mammoth (Grades 1-7)
 Singapore Math (Grades K-6)
 Life of Fred(Primary-College)
 Art of Problem Solving (Pre-algebra and up)

On Level Checking by reviewing a curriculum overview

You can get a feel for placement by looking at an overview such as at the  Khanacademy which shows a list of all of the math by grade.

Suggestion for getting started

While you may want to start looking at an overview and see what you recognize from your child's homework, it is easy to make the mistake that recognizing the content indicates mastery. Also, beware of your child recognizing that they have seen the material and claiming mastery. Please, evaluate carefully to see what your child has actually mastered. Be aware that your child's mastery may be on grade-level, below, or above. It is easiest if the child has holes in their knowledge or is below level if the program is totally different from their prior materials. Then there is no loss of status in starting a bit below where they test and working from there to ensure a solid foundation.
For evaluation of their knowledge and mastery I strongly suggest utilizing either the Saxon math placement or state-level test to get a basic idea and then work in a bit at a time Singapore Math or Math Mammoth or both. Both Singapore Math and Math Mammoth heavily include word problems in the material and this is reflected in the test.

What if my child made a perfect score on the placement test?

Congratulations to your child! Keep doing higher level tests until your child hits an area that needs work or runs out of tests.
If he runs out of tests, try the math section of a practice  SAT(r).
Puzzle and contesting sites can also broaden the interest of a mathematically adept child looking for challenges.

Ray's Arithmetic Series


The phrasing can be quaint, but the price is right and the books are formatted to largely have the student help themselves.
Ray's Arithmetic series can be found multiple places online as the series has moved out of copyright. The math topics covered have not changed since these books were written and they can still provide thoughtful and complete coverage of the material. One advantage of a text that can be downloaded is that if there is limited internet availability then these materials can be used easily once obtained.
I will mention two places these are currently, although you may find alternative locations as well. On archive.org the books can be read online or downloaded in many formats including PDF, EPUB, text, and kindle.
Ray's Arithmetic blog hosts PDFs of most of the texts as an alternative download location and has added some videos to accompany the book. I have not reviewed the videos, but feel free to comment in the blog about these or other resources and I will make notes as time allows.

American Institute of Mathematics Reviewed Text books

For a number of years members of the American Institue of Mathematics have been reviewing free and low-cost math texts to select ones suitable for a standard college level class. As there is considerable overlap between the lower level college courses and the high school courses, these materials merit consideration.

Texts have been reviewed and recommended in the following groups:
Liberal Arts Math, Elementary Algebra, College Algebra and Precalculus,
Trigonometry, Calculus, Differential Equations, Linear Algebra,
Introduction to Proofs, Discrete Math, Combinatorics,
Computing and Numerical Analysis, Number Theory, Abstract Algebra,
Real Analysis, Complex Analysis, Geometry and Topology,
Probability, Statistics, and Logic

Item Description

  Khan Academy

Khan Academy

KhanAcademy allows the creation of a user account to progress through levels of math from kindergarten to beyond calculus. For an elementary student it is often suggested that the user begin at kindergarten and review and test out of the earlier material. This allows students who have previously been hesitant or un-successful in math at their grade level to back track and have math that is fully in their grasp. When the math is suddenly easy, they find that what had been scary is fun. As the review fills in holes in their knowledge the challenges are manageable and often they discover that they like math after all. For a math wiz who has mastered these concepts, point out that as they test out of sections that they can move on to a continuum of challenges at their own pace.
If you want a single resource for math, pick this one. Although nothing is a fit for all students, the adaptive nature and ability to go at your own speed above or below your grade level make this a flexible choice.
