Celebration! Danica McKellar has released her latest math book for girls, Girls Get Curves!

McKellar recently did a really thoughtful interview with NPR about her latest book, which focuses on geometry. One of my favorite parts is this bit, when she talks about taking her first college math class at UCLA:

I was actually worried about taking a math class. I didn’t know that I’d be able to handle it. And here I scored a five on an AP Calculus BC exam. Talk about perceptions. I didn’t see myself as being good at math even though I was. And that’s one of the things I’m tackling in the books. But when I did jump into that math class, despite my concerns and my fears, I did really well and I was hooked.

I was like, wow, I suddenly felt valued and important for something that had nothing to do with Hollywood. It had everything to do with something that I was building from the inside out, and you don’t have to have been on television to struggle as a teenage girl with your self-image. And that’s why I know that math is an amazing tool for all girls to find themselves, to find something that they value themselves for.

Because I admire Danica and share with her a mission of helping girls (and guys too) really GET math in a way that is fun and meaningful, I’ve read a lot of her interviews very closely (and I even got the chance to interview her myself about her third math book for Wired’s GeekMom blog — check it out here). I’ve heard her talk about how doing a difficult math problem during college would make her euphoric, and her journey of becoming a math major.

But this is the first time I’ve heard her talk about experiencing math as a refuge – a place where you can incubate and develop your own abilities and intellectual strength and work “from the inside out” in a way that has nothing to do with appearances.

This vision really resonates with me — and I hope that all girls (and guys) can experience math this way.

Would you love to experience math as a refuge – even if right now, you might not be sure that it’s possible to ever regain your confidence? Give me a call at 617-888-0160 or email me at rebeccazook@gmail.com, and I’d be happy to set up a time for us to have a conversation about what’s going on and look into whether or not it would be a good fit for us to work together one-on-one!

What an awesome way to remember what some of the essential functions look like!

Next time one of my students needs to remember what a function looks like, I’m gonna say, “Let’s DANCE!!”

This goes out to all the kids who are working on summer math packets without having a textbook to refer to. If you need a good online math reference, I highly recommend Purplemath (one of my personal favorite math websites).

This site has a GREAT lessons index so you can quickly find the exact topic you need. The lessons (written-out explanations) are very thorough and easy to follow. They’re not written like a math book, but like having someone really smart and kind explain things to you in a conversation. The lessons do an excellent job of going over concepts AND steps, integrating the “what do I do?” with the “why it works!”

The site also features community forums sorted by level—starting with arithmetic and going all the way up to trigonometry. So if you have a math question, you can post it in the appropriate forum and get help from other community members. Elizabeth Stapel, the founder of purplemath, frequently responds to students’ posts in the forum herself!

Thank you, Elizabeth Stapel, for this totally user-friendly and expert site!

Five fun ways to help your kids learn math this summer (online!)

Here’s a fun way to remember the formula for surface area of a cylinder—singing these lyrics set to the tune of Camptown Races (in the style of Foghorn Leghorn):

2 times pi times r times h; that’s the middle.
2 times pi times r times r; top and bottom, too.
Surface area!
Of a cylinder! It’s
2 times pi times r times h plus two times pi times r times r.

If you’re not sure about how to fit the lyrics with the Camptown Races melody, just listen to the intro of this sweet rendition on YouTube:

With this handy mneumonic device stuck in my head, I feel the urge to belt “Surface areAAAA! Of a cylinDERRRR!” while walking around my neighborhood and puttering around my kitchen!

Many thanks to Becky Brickell for sharing this great idea on the Texas Instruments Classroom Activities website!

Five fun ways to help your kids learn math this summer with rock songs and raps

Growing up, I remember learning to remember the difference between the greater than and less than signs by imagining a hungry alligator with an open mouth getting ready to “eat” the bigger number.

I recently got to work on this concept in an online tutoring session with a student of mine who’s a fifth grader.

First we had a regular < sign and we talked about the "alligator" idea.

He drew in some pointy alligator teeth:

Then he spontaneously drew a whole alligator:

As we worked on different inequality problems, he took it further. He drew a picture of a bird and explained that the bird’s closed little beak is shaped like an inequality sign. The bird would go for the smaller meal, while the alligator would go for the bigger meal.

And he topped it off – with sound effects.

The smaller number, which the bird would eat, has a “peck peck” sound. The larger number, which the alligator would eat, has a “chomp chomp” sound. Oh my gosh, I love it!

I’d never seen the alligator metaphor pushed this far before, and I wanted to share my student’s creative ideas!

What’s your favorite way to remember (or teach) the difference between the two signs?

Five fun ways to help your kids learn math (this summer)

Pizzas. They’re the best way to represent fractions, right? Everyone has seen a pizza. Everyone knows you can slice a pizza different ways. When you need to visually represent fractions, pizzas are the go-to metaphor, right?

Well, that’s what I thought until I tried using pizzas to teach equivalent fractions. Sure, it’s easy to use a pizza to represent quarters, sixths, eighths. Thirds aren’t even too bad.

But just try dividing a circle into five equal pieces. Or seven. Or ten. Even though I’m a grown-up and a professional math educator, it’s really hard for me to consistently do this.

And as for showing visually how two fifths equals four tenths? Unless I do an impossibly immaculate job of dividing those pizzas into pieces, forget about it.

Are they really the same?

Fortunately, I’ve found a much better way to represent fractions visually: the Math-U-See fraction overlays. If we’re going to use a food metaphor, they’re flat and square, like brownies from a square pan.

And like brownies, they are much easier to slice evenly than pizzas. In fact, because they’re reusable transparent overlays, you don’t even have to draw (or slice) anything. You just arrange them on top of each other.

Check it:

Awwww, yeah! Those fractions are DEFINITELY equivalent!

You can use the overlays to represent basic fractions with divisors from two through seven, or combine multiple overlays to build other denominators.

Not only do they make it really easy to see how equivalent fractions work, but using them is way easier than drawing pizzas and hoping the slices come out even.

The fraction overlays make the concepts extremely clear, and because they’re tactile, visual, and kinesthetic, they make fractions feel like a game instead of work. Whenever I’ve used them with my students, either in person or during online tutoring sessions with a webcam, they’ve react the same way: “This is fun!”

Now that’s how I want my students to feel about fractions!

How to find a good math tutor
Be yourself, do what you want, wear what you love (Ada Lovelace/Coder Barbie Follow-Up)

Do you need a way to remember unit conversion effortlessly and forever? Or just a way to calculate how many cups there are in a gallon?

Here’s how to figure it out. Draw a gallon man!

First, draw a really big capital G. (This is the gallon.)

Inside the G, draw four big Qs. (These are the quarts.)

Inside each Q, draw two Ps. (These are the pints.)

Inside each P, draw two cs. (These are the cups.)

For the final flourish, draw an arrow to one of the cs and write “8 ounces.” (There are eight ounces in every cup.)

When one of my students, a fifth grader, taught me about Gallon Man, I thought, I wish I had learned about this in fifth grade! My entire life, I’ve had to look up each of the conversions and never really internalized how they all fit together.

Since I’ve been introduced to Gallon Man, I’ve gleefully shared him with a fourth grade tutoring student (online), a friend who is a professional organic farmer (in person), innocent bystanders (at a restaurant), and most recently, my Mom (over the phone…”first, draw a really big G…”)!

They’ve all found Gallon Man helpful. Responses have included: “Can I take that drawing home with me?”, “Oh…I get it!”, and “I’m going to hold onto this.”

Gallon Man is totally visual and works for many learning styles. You can SEE how many quarts are INSIDE a gallon. Gallon Man is intuitive for all grade levels (unlike dimensional analysis, you don’t have to worry about the numerators or denominators). Gallon Man is practical. You can use it in your kitchen or in the grocery store. Gallon Man is easy to remember. And Gallon Man is fun to draw!

Gallon Man has recently gotten some airtime from other math bloggers, including Sam J Shah, who pointed out that it really helped him to see someone drawing Gallon Man. Here’s Sam’s post and video.

Yay for mnemonic devices!
