]]>Several years ago, when my son and I were working on multiplying fractions, we were doing some work with multiplying a whole number by a fraction, specifically a proper fraction, where the numerator is less than the denominator. The example was 5/8 x 12, and the focus of the lesson was supposed to be that in order to multiply a fraction and a whole number, you change the whole number into its equivalent improper fraction, in this case, 12/1, then solve. (Cross cancel, multiply the numerators, multiply the denominators, get your answer).
Okay, so he had no problems with the process. What did bother him was when he got the answer and saw that it was less than what he started with. At first, this didn’t make sense to him because, as he put it, “Doesn’t multiplication mean more?”
So we talked about it, and with a little more contemplation:
Now, I realize this example demonstrates a rudimentary understanding of numbers, but, to me, this also illustrates a problem I think kids can run into when it comes to learning math: the difference between knowing how to perform the steps of a particular process versus understanding why an answer does or does not make sense. Sometimes, we can learn a process mechanically without thinking about what we're doing in concrete terms. Maybe the pondering comes later – or maybe it never comes at all.
I suspect this may be one reason why kids that do great in basic math and pre-algebra seemingly hit a brick wall when they get to Algebra. Could it be because when studying Algebra, you may learn to mechanically follow steps to solve complex equations without really comprehending the underlying logic? Or maybe some kids never get a good enough grasp of the basics to sufficiently tackle “higher math?”
I’m not sure where the breakdown occurs, but I do know that some people have a great facility with numbers (I am, unfortunately, not one of these people), while others may struggle all their lives with math, and others are somewhere in between. Is the facility with numbers from having been taught well, a result of some innate trait, a combination? How do you determine if your child has a sufficient understanding of math principles? Do you assess with worksheets and tests or use another method? Please leave a comment. And, if you need some free resources for learning fractions, decimals, percents, ratios and proportions, take a look at these:

]]>Hope you are having a swell summer. After a grueling week in Orlando, I'm happy to get back to the more relaxing (and definitely less taxing) resource planning for the upcoming school year.
For those of you also in planning mode, here are some high school materials you may find useful:
Prentice Hall Algebra 2: So far, I've homeschooled two children at the high school level, and have used a variety of math resource types, including textbook-based (with a hodgepodge of videos not specifically correlated to the text); CD-ROM-based lessons with textbook from a homeschool academy; and totally online courses with no textbook at all. I have found that my high schoolers, although typical "cyber-generation," actually prefer hard-copy when it comes to certain things, math being one of them. So, I'm thinking of using the Prentice Hall Algebra 2 textbook, which appears comprehensive, and has a companion website with projects and real-world applications, and computer-scored lesson quiz.zes, and chapter tests. In addition, here are three sites with video lessons that correlate specifically to each chapter of the Prentice Hall text.
Other Math Textbook/Video Correlations: If you are looking for teaching videos related to specific textbooks for other maths, try HippoCampus. The site has also just added an Art of Problem Solving collection with videos that break down how to solve problems.
Saylor's K-12 Section: Not sure if I mentioned this before, but Saylor.org, which has hundreds of free, online, self-paced college-level courses, also offers some middle- and high-school courses. Currently, there are 9 of them in the areas of English Language Arts, high school math, and two "electives" (one on the Common Core and one on SAT prep).
Enjoy your summer.
]]>Signs of summer are all around us, and our family looks forward to winding down in some areas, and ramping up in others. Still, I find, with my own kids, that math is one of those things that, if not practiced all year, is easily forgotten. So, although I don’t school year-round, we do try to keep the math going, emphasizing a more game-like experience.
If you need some material for your own review endeavors, or maybe you’re planning for the fall, here are some resources that may help, including a list of links to free courses in high school math.
Math Playground: In addition to arcade style games, this site has some interesting additional features, such as:

]]>It's a valid question educators are asking themselves more and more in the face of dismal test scores and the fact that many high school students have never gotten a good handle on basic math, the stuff we use everyday.
Yet despite the fact that most people will not go into engineering or use higher math in any way in their lives, it continues to be forced on students and hinders many from pursuing their true interests. Why should passing Algebra be such a determining factor in a person's future? (Homeschoolers, too, are affected by this either through state graduation requirements, or via college entrance exams).
This math teacher for the middle- and high school grades doesn't think that makes any sense:
"Too many of the nation’s 14-year-olds inadvertently narrow their college options before they’ve even settled into high school." The reason? They can't get past the "gateway" course, Algebra 1. Many fail a second time and never become proficient at it.
Some argue that the reason students are unsuccessful is because the course as it is generally taught is badly designed.
"Algebra, as we teach it, is a death march through endless disconnected technical tools and tips, out of context....The course has no big ideas, no direction, no purpose. And when was the last time you had to graph inequalities?"
Others argue Algebra must be taught because it is necessary for developing critical thinking. But there are alternatives, both to the way Algebra is taught, (relate it more to real-world problem solving), and for the course itself (rigorous courses in statistics and probability, or philosophy and logic to develop reasoning and analytical skills).
And wouldn't we be serving students better if we made sure they had a good, working understanding of things like decimals and percents, how to measure square footage, budgeting and personal finance, how loan amortization works -- you know, some practical stuff?
I don't think Algebra and other higher maths should be scrapped completely from high school courses of study. I just don't understand why these courses are a requirement for everyone. Hopefully, this will change.
In the meantime, the next time one of your kids asks, "Why do I have to learn this?" or "What am I ever going to use this for?", here are two sites that attempt to provide some answers:
]]>I came across some interesting math puzzles over at MathPickle. My daughter likes doing dot-to-dot puzzles, but on this site, you'll find these puzzles with a twist: you use a ruler and only connect the pairs of dots that are a specific distance apart. For example, the puzzle starts out looking like this:
And if you connect all the dots properly, (in this case, those that are 5 cm apart), you'll get a design like this:
This is one of the easy ones. There are 23 progressively harder puzzles, with solutions, that you can download from this page, along with other puzzles.
We've also been looking at symmetry:
and the way 3D shapes look when they are flattened out (noting things like the number of surface faces, sides, and vertices):
You can find both of these free downloads at Nyla's Crafty Teaching.
]]>A free Algebra 1 course just came out this week, this one from Curriki, a provider of free, K-12 open educational resources. This is a full course, broken into modules, so you can use it in its entirety, or just the parts you want. The course includes lesson plans, with links to related Khan Academy videos, worksheets and assessments with their answer keys, and each unit ends with a real-world project. If you haven't been on Curriki yet, click on over. They've got lots of good stuff and the site's pretty easy to search.
Another free Algebra 1 course just newly released is available from SAS Curriculum Pathways. Also modular with video lessons.
Other free high school math courses are available at:
Came across this site called, Mangahigh, which offers free math challenges and games for ages 7 - 16. You can choose games by grade level and also by topic. For example, you can have a child in the elementary grades play a game that reviews certain times tables, or gives them word problems to solve. High schoolers can play games to help them brush up on Algebra, Geometry, and Statistics and Probability.
The games are designed to adapt in difficulty to the ability of each student, and they correspond to Common Core standards. You can assign exercises to a student, and then when your child logs in, he or she will be shown all the math games scheduled for them.
There's a lot to see, so it's best to just go to the site and try it out yourself. You can register for a free account by putting in a "school" name (some states require homeschoolers to register as "schools" with their own names), and upload an Excel spreadsheet of "students". It's easy to do.
]]>Here’s a sample:
A standard checker board has 64 squares alternating black and red on an 8 by 8 grid. How many of the 1296 rectangles on a checkerboard contain more than one red square?
