Fun At Home Activities

Kids home from school? Some fun activities to try…. There are lots of fun things to do on the Math Fairy website and on other great websites. I’ve been thinking about some ideas since we started to learn that school would be closed so I thought I’d share those ideas here… Try a Fibonacci Walk! Try a Fibonacci Walk! Recall that the Fibonacci sequence is a pattern of numbers identified hundreds of years ago by an Italian mathematician. The pattern is additive and goes like this….1,1,2,3,5,8,13,21,34,55…. Where you add the two previous numbers to derive the next number. Example: 1+1 = 2, 2+1=3, 2+3 = 5, 3 +5 = 8, 5 + 8 = 13 and so on. One of the super cool, mathemagical things about the Fibonacci sequence is that it exists in nature. The spirals of a pinecone expand in a Fibonacci pattern, leaves can grow from a Read More →

Homemade Play-Dough

Play-Dough ~ great for kids of all ages! Playdough ingredients: 2 cups all-purpose flour 3/4 cup salt 4 teaspoons cream of tartar 2 cups lukewarm water 2 Tablespoons of vegetable oil (coconut oil works too) Food coloring, optional Quart sized bags Stir together the flour, salt and cream of tartar in a large pot. Next add the water and oil. If you’re only making one color, add in the color now as well. Cook over medium heat, stirring constantly. Continue stirring until the dough has thickened and begins to form into a ball. Remove from heat and then place inside a gallon sized bag or onto wax paper. Allow to cool slightly and then knead until smooth. If you’re adding colors after, divide the dough into balls (for how many colors you want) and then add the dough into the quart sized bags. Start with about 5 drops of color and add Read More →


Gack ~ best for older children who will not ingest! Ingredients 4 ounces of school glue½ cup water + ¼ cup hot water½ teaspoon BoraxFood coloring Directions Pour the glue into a container with the ½ cup water. Mix with a spoon. Add the food coloring. Mix well with the spoon. In a separate small bowl, mix ½ teaspoon Borax with the ¼ cup hot water. Make sure to mix gently until the Borax is completely dissolved. Pour the Borax water into the glue water. Begin mixed and watch the Gack form! So cool! Then start mixing with your hands. Have fun! Did you know Gack will bounce? (p.s. Beware of Gack and carpet. I have had it stick to carpet and fabrics before. Great thing to play with in the kitchen or outside.) Sourced from:

A response to Stuart Reges “Why Women Don’t Code”

Today I opened up the Sunday Seattle Times newspaper for a relaxing read with my morning coffee. I noticed a little “letter to the editor” in which a professor from the University of Washington responded to women who had responded to his article about women in the computer sciences fields. As a new computer coding teacher I was immediately intrigued. I googled Mr. Reges’ article and read it. My primary thought as I was reading through his long article was, “huh”. I know, not very intellectual, but I am firmly perplexed by his apparent position that men and women have different brains and so choose different careers. I realize that the nature vs. nurture dialogue rages on and has for the past several thousand years but I was under the impression that the current brain research had debunked the idea that human brains are hardwired for one type of learning Read More →

Math or maths, if you will, is a funny subject. As you know from reading other mathfairy thoughts, I personally find math incredibly magical: The Fibonacci sequence in nature! Ten fingers and a base ten number system! Triangles! And I find that almost everyone I meet has very strong feelings about math. I was speaking with my 84 year old father recently. He’s quite brilliant. My parents are both amazingly smart, very articulate, well educated, you get the idea…my dad and I were discussing some of my latest teaching experiences and ideas about math in general. He was talking about how math is a language for the world. I, of course, had to proclaim my favorite quote, “mathematics is the language with which god has written the universe” from Leonardo da Vinci. And then, surprisingly, my brilliant father said, “yes, a language I don’t understand and never have.” I was Read More →

The 5×5 Grid Game or FUN on the day before vacation!

I will just start by saying that I did not create this fun math game. I didn’t even find it! A member of my awesome math team emailed everyone a link to a math teacher’s blog, in which she explained the 5×5 game. I’ll sum it up here, but definitely go check out her blog. She has a lot of great ideas!×5-most-amazing-just-for-fun-game/ Let’s start by discussing the day before vacation in middle school. Ugh. The kids are either excited or anxious or both. And that doesn’t translate into an excellent learning environment. When I taught in the Catholic schools the day before vacation was very ritualized….we would have church, we would have traditional parties organized by the parents, etc. It was still tiring and the kids were still super amped up, but at least there was some structure provided by the nature of the day. In public school, where Read More →

Teaching with whiteboards

Using “standing” or wall mounted whiteboards has changed my teaching. It’s amazing to me that something so simple could have such an enormous impact. But it has… This is how it happened: a couple years ago I was channel surfing. I never channel surf and I rarely watch TV. But I happened to have some free time and I happened upon a cool documentary about teaching called “Teach”. It followed three teachers and their journey through a school year. All of them had very cool and interesting ideas. One teacher was teaching algebra and had the kids doing something she called a “360 classroom”. She had all the kids on whiteboard around the room. She could turn in a circle, hence the “360”, and see what everyone was doing. I thought that was so cool! I went back to school the next day totally fired up! I emailed my principal Read More →

Teaching area of complex shapes

Today I saw the movie, The Martian. Unbelievable. I had read the book. I knew it was going to be good. But I don’t think I’ve ever been on such a math high before! If you are a math teacher, you are probably among the people in this world who can understand how completely amazing it is to see Math Damon, huge on the big screen, saying (something like), “You’re going to die. You can die or you can do the math. Just solve one problem and then solve the next one. Do the math.” I think he said, “Just do the math” like 6 times in that movie! So great! I think we may start having a Martian math problem of the week…. I’m getting ready to correct my quizzes for last week. I always correct quizzes over the weekend. Probably sounds sort of appalling to many people but Read More →

Teaching Order of Operations

Today we tried something different for teaching Order of Operations and it was GOOD. Here’s the set up: We made 8 1/2×11 laminated number cards, two sets of 0 through 9, as well as operator cards, two sets of +, -, *, division symbol, ( and ). Then I was going to have the kids use scratch paper, which will work just fine, but decided at the last minute to use the mini-whiteboards (and the standing white boards ~ more on these later). I think that was a good choice. The kids really love them and it adds an element of engagement. Do you have those? They’re not that expensive anymore and well worth the investment. That’s it on supplies. Then I started by doing a quick review/overview of Order of Operations. These are 6th graders and they had seen this math in 5th grade. Then I explained that we Read More →
