Introduction to Algebra We live in a world of numbers. You see them every day: on clocks, in the stock market, in sports, and all over the news. Algebra is all about figuring out the numbers you don't see. You might know how fast you can throw a ball, but can you use this number to determine how far you can throw it?

Natural Math In a Math 2.0 email group conversation about screencasting and tools like vZome, Brad Hansen-Smith of WholeMovement posed this question: Can you explain how using this virtual zome tool will give students a better understanding of polyhedra than actually building it from scratch for themselves? I have the same question about any virtual experience when compared to actual experience of doing something. Here was my reply: It is better to have both experiences. 1. 2. Step review works wonders with sharing. 3. The word “easy” here is the difference between thousands and millions doing the three activities I described above. I posed the same question to Katherine, my daughter, who added two items to the list: In virtual constructions, you can see infinity. I am adding another key item that came to mind: modularity.
How to Recognize a Successful Homeschool Math Program photo by Dan McCarthy (cc-by) After teaching co-op math classes for several years, I’ve become known as the local math maven. Upon meeting one of my children, fellow homeschoolers often say, “Oh, you’re Denise’s son/daughter? You must be really good at math.” The kids do their best to smile politely — and not to roll their eyes until the other person has turned away. I hear similar comments after teaching a math workshop: “Wow, your kids must love math!” In fact, one daughter expressed the depth of her youthful perfectionist angst by scribbling all over the cover of her Miquon math workbook: “I hate math! Translation: “If I can’t do it flawlessly the first time, then I don’t want to do it at all.” photo by Jason Bolonski (cc-by) Measuring Math Success I don’t judge my success as a math teacher by whether my students enjoy the subject. How, then, can I tell whether my kids are learning math? I talk to them. I ask questions like “How did you figure that out?” Thinking like a Mathematician
Introduction to Geometry More than 2000 years ago, long before rockets were launched into orbit or explorers sailed around the globe, a Greek mathematician measured the size of the Earth using nothing more than a few facts about lines, angles, and circles. This course will start at the very beginnings of geometry, answering questions like "How big is an angle?" and "What are parallel lines?"

Workboxes: Math At a conference last fall, I heard Kim Sutton mention something about using Zoo Pal Paper Plates to show parts and whole in math. She briefly described putting the parts in the ears and then showing the whole in the larger plate area. I couldn't find the zoo plates locally (Amazon link is below), but decided to try it with a plastic plate from a local one buck store. I've used this a couple different ways to explore the part-whole relationship in addition with my 5yo... With Dice: He tossed one die into each of the smaller compartments and put that many items (I used centimeter cubes) in each dish. With Pre-Written Number Sentences & Penguin Pieces: I wrote several number sentences. This could easily be replicated at home or school.

10 Unusual Ways to Explore Math I confess. I never really liked math. I played the school game well so I received pretty good grades, but after I passed the test (even after receiving an A in most cases), those rules, theorems and facts didn’t stick around for very long. The problem was everything was drilled into me, or as I like to think now, drilled out of me. I’m so excited that now, as an adult, I have the time and opportunity to get to know math all over again with my kids. Over the next few weeks, I’m going to take subjects traditionally taught in schools, one subject each week, and show you how they can be looked at in unusual ways. Here’s a list of ten unusual ways to look at math. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Do you have any ideas about how math is connected in unusual ways to your world? Did you like this post?
