To Accumulate a Rate — Integrate!

Teaching High School Mathematics


My name is Kaleb Allinson and I’m a math teacher at LSHS in Lake Stevens, WA. I’ve been teaching since 1999 and I currently teach Algebra and AP Calculus AB. I’ve been reading some math teacher blogs for the past 5+ years and have really enjoyed reading different insights and discovering cool new ideas. Although I work with a great staff, it’s difficult to find the time to get together and talk about the things that come up so easily in the Math Twitter Blogosphere. Improving my teaching skills has always been important to me and so I thought that I would start a blog to help me reflect on my teaching. Occasionally I hit a lesson that I really love, but I’m not very good at recording the unique idea I came up with for use the next year, so the only way it gets into my standard set of lessons is if I remember it when it comes time to do it again. Writing about these moments will help me grab those ideas and improve on them the following year. This year I will also be the math department head which will come with some new challenges for me. (update: I’ve spent 4 years as department head and passed the baton on.) I hope that this blog will help me to improve my skills as a teacher and in turn help my students to have a greater understanding and hopefully a love of mathematics.

    Hi, Kaleb,

    I came across your blog via David Wees, and as a fellow mathematics educator I thought you might be able to help in spreading the word about an educational TV show for preteens about math that we’re putting together. “The Number Hunter” is a cross between Bill Nye The Science Guy and The Crocodile Hunter — bringing math to children in an innovative, adventurous way. I’d really appreciate your help in getting the word out about the project.

    I studied math education at Jacksonville University and the University of Florida. It became clear to me during my studies why we’re failing at teaching kids math. We’re teaching it all wrong! Bill Nye taught kids that science is FUN. He showed them the EXPLOSIONS first and then the kids went to school to learn WHY things exploded. Kids learn about dinosaurs and amoeba and weird ocean life to make them go “wow”. But what about math? You probably remember the dreaded worksheets. Ugh.

    I’m sure you know math is much more exciting than people think. Fractal Geometry was used to create “Star Wars” backdrops, binary code was invented in Africa, The Great Pyramids and The Mona Lisa, wouldn’t exist without geometry.
    Our concept is to create an exciting, web-based TV show that’s both fun and educational.

    If you could consider posting about the project on your blog, I’d very much appreciate it. Also, if you’d be interested in link exchanging (either on The Number Hunter site, which is in development, or on which is a well-established site with 300,000 page views a month) please shoot me an email. We’re also always looking for input and ideas from other math educators!

    Thanks in advance for your help,

    Hi Kaleb, I’m a mathematics education PhD student at SFU in BC, Canada. I’m really taking interest in looking at blogging as a form of PD for math teachers. Would you be willing to chat with me at some point down the road to discuss your experiences as a teacher blogger? (I could use some tips too as I’m just starting out). Send me an email if you can.

      I’m not sure that I’m the best person to ask. I’m not good at regular posting. I get into it and then move on to something else. It is nice to write down what you’re thinking. My main problem is that I don’t have a lot of interest in writing… just math, so…

        Great! I’m not good at regular posting either, but I really enjoy looking through your posts. Maybe we could connect via email?

    Hi Kaleb,

    You taught for Mathematics for over a decade? That’s awesome, we definitely can learn from you if we ever got the chance! Anyway, this is about a Mathematics mobile app, ‘Little Wizy Kingdom’.

    To sum up the game, think of it as a combination between Farmville, Mathematics and logic thinking.
    ‘Build your kingdom by solving Mathematics questions and puzzles!’

    We believe that Mathematics is the fundamental of our world, a scroll, a book or poem can be burned and lost, but mathematics can never be destroyed.

    Little Wizy Kingdom is a an app with great quality and truly made for the next generation. And of course, the app is designed not only to teach, but to generate a ‘Mathematical mind’.

    Thank you! The future of humanity starts from small steps! Do let me know if you’re interested in taking a look at this app, it would be great to have your feedback on Little Wizy Kingdom.
