HOT APPS for HOTS: iCard Sort

iCard sort is a great app to use for vocabulary & sorting. The apptivity below is a jeopardy-like vocabulary lesson that involves matching mathematics vocababulary to its corresponding definition. Lesson, extensions,and student record sheets are provided.

Handouts:

This activity can be delivered as a review or as a pre-activity. If teachers choose to do the activity before the lesson, they may want to allow students to use resources to locate words as well (textbooks, Dictionary.com, Ask.com, Answers.com, etc…).

Bump it Up: Another extension to this activity would be for students to use the Contacts app (an standard app on the device) to build a math vocabulary database with images of the vocabulary (captured from the device or from the internet), a website that may give more information, & the definitions written in the notes field. (see Signs of Math Bump activity).

If a teacher has issues beaming or blasting decks due to wifi or internet issues, consier having students create the deck to match the grid. It may take a little more time but the activity will be saved.

All definitions were used from MathWords.com.

Flipping the Classroom

I recently was asked to be part of a Think Tank to promote global education through the use of technology integration in our schools (many times highlighting the power of mobile devices & Web 2.0 tools). I have since then been inspired to share this video and its message with anyone and everyone that will lend me their ears.

As a Math teacher, I am familiar with the direct teach… assign guided/independent work in class… work not finished becomes homework… homework is not completed or completed inaccurately (and oftentimes with misconceptions) due to lack of instructional support at home. This cycle has gone on for much too long and is clearly still a practice as we see multiple interventions occurring to save students from failure on high stakes assessments and grade level promotion.

Though I was aware of the Kahn Academy app and am quite familiar with other Math apps that can be used to build math capacity and strengthen math skills, it was not till last week when the idea of “flipping the classroom” was added to my vernacular. How exquisitely simple the idea for such a powerful change to pedagogy and student results. Ask yourself, “How would our knowledge of Math or Science differ if Einstein & Newton had left detailed videos to explain their theories and concepts?” The entire video is linked below (it only takes 20 minutes to be inspired).

Let’s use video to reinvent education: Salman Khan on TED.com.

While this is not meant to be a one-size-fits-all approach, it does have many benefits for our learners:

  • allows learners who fall behind to not feel ashamed in asking for help as they can access the videos from home (rather than ask a question in front of the class)
  • allows self-directed and self-motivated learners to move ahead at a pace that is right for them
    • One example that was given during our meeting was that of a second grade student who had not qualified for the GT program but was extremely interested in what those students were doing in the program – especially with Math. The GT teacher directed him to her website with all of her teacher videos and assignments for the next few weeks. He quickly returned and wanted to know when she would be posting the next video, as he had not only completed the first video and assignment but all of them. Some times the walls of our classrooms are too small to contain the voracious appetite for learning and discovery that many of our students possess. She has since then began coaching him as a student in Khan Academy.
    • I too had a similar story. I taught a Pre-Algebra Advanced course for 7th grade students. While the students were predominantly GT, the levels and spectrum of GT varied throughout the classroom. One student always stood out to me. He would receive perfect scores on his assessments and he would actually read ahead to the next 2-3 chapters in the Math textbook. I recommended him to move to Algebra that year and he did well being two years ahead of his peers in Math. At the time we did not have access to or knowledge of the wealth of video and online resources available for a student of his caliber. Looking back, this would have been a wonderful gift to empart to all of my Math students.
  • allows students who missed class or have transferred from another campus, district, state to fill in the gaps (lessons & skills) that they may have missed
  • provides copious amounts of data (e.g. time spent on video or activity, problems missed, how many attempts, etc…) to teachers to track students and provide more resources and remediation of needed

Much of the Criticism I have seen against the Flipped Classroom highlights the lack of technology available to access the videos, inability and delay to ask questions, the idea that videos should not be the primary delivery method for all students, the necessity of additional resources to accompany lectures. While I do agree with many of the criticisms highlighted in this article, I believe there are ways to work around them:

  • It is true that not all students have internet access at home. However, many of them have mobile devices that will solve this issue. This may lead to a BYOT (Bring Your Own Technology) classroom concept as well. For those that do not, perhaps teachers and schools can agree to some sort of check out process for mobile devices.
  • It is true that while watching a video, you can not ask questions and have them answered. Even if students do write down their questions for the next day, they may be overwhelmed with how many questions that have. This is where social media and peer collaboration is key. First, most teachers will have a good idea where students will encounter an issue and they could supply additional resources to scaffold and supplement these topics and ideas. Also, peers are an excellent (and oftentimes underused) resource – especially if the teacher creates some form of online learning community (e.g. Edmodo, Moodle) for students to collaborate and support each other.
  • It is true that this should not be a one-size-fits-all approach nor the only instructional resource in the classroom. It is more the idea than the resource itself and it could be used as much or as often as an instructor sees fit. It is not intended to completely replace the role of the teacher or of good current instructional practices.
    • Some schools may call upon teachers who are strong orators and have a way with teaching a particular concepts to create videos of their lectures and disseminate them for other classes. Others may want to record student explanations as well. Both of these ideas can be easily accomplished using a document camera (the actual person delivering instruction would not even need to appear in the video – just the action of explaining the instruction or problem/examples).
    • Teachers should work together to create and supply resources to accompany videos. Resources could range from PPT’s, to interactive websites, to SMART lessons, to podcasts, to videocasts, to apps, to Khan Academy activities, to math-themed children’s books, to ePubs, to online learning communities. A veritable scmorgasbord of resources and support to meet the needs of any and all learners.
Though the focus on this blog is Math, the idea of reversing your classroom could be applied across the curriculum. How will you FLIP YOUR CLASSROOM?

Podcasts 4 Math

Our Web 2.0 Part 2 Moodle course provided some wonderful discussion on useful Math podcasts. Why reinvent the wheel? Here are some of the resources (with descriptions) that were provided from teachers enrolled in the course. Use these as mini lessons, reviews, independent study pieces, or to clear up common misconceptions.

  • The Video Math Tutor–  Even during summer kids can access podcasts to see how some of the math they will be doing in summer is done, it serves as a good review and resource. Tips on how to solve algebra problems, gives graphing calculator tips, brian teasers, and other tips for both students and teacher.
  • Edutopia (Math)– I like this feed because it is a good resource for teachers when they need new ideas or a new insight to approaches or thoughts on teaching. “Teaching Elementary Students the Magic of Math” really shows how math can and should be integrated fully into all subjects of learning.
  • The Wizard of Oz- From Fractions to Formulas – I love to show that math is not scary.  When information is presented to the students in a familiar or entertaining method it grabs the kids attention and diminishes fear of a subject.
  • Math Guy podcast – Fun math games and trick. Gets kids excited about math and using numbers
  • Mathtrain.TV – Review over middle school concepts, interest, percent of a number, unit cost.
  • Khan Academy – Geometry: Khan Academy has podcasts in all of the subject areas in mathematics. It gives very detailed and drawn out explanations of various mathematics topics, including geometry. It is an excellent podcast for students who struggle with their work or for those who would like to see more examples outside of class.
  • Mr. A’s Geometry Podcast: This podcast is similar to the Khan Academy podcast. Detailed explanations of various geometry topics are shown, but more closely resembles what a student would
  • Math Mutation: This podcast provides weekly topics in mathematics that are described as “fun, interesting and weird corners of math.” It can be used to show students than math can be fun and interesting.
  • Math by Design: “These videos and support materials will give you another weapon in your answer arsenal. In the videos, students meet people whose everyday, real life includes just the kind of mathematics they explore in Math by Design. Use the Discussion Questions and Related Practice resources to extend and enrich your students’ video watching experience!”
  • Media 4 Math: Videos range from algebra applications in the mortgage crisis to exploring 3D Geometry. Also has a great section on Math in the News with PPT presentations to accompany.
  • Is All About Math: Math is a subject area that is ever changing. Even though the concepts remain consistent, the strategies and techniques for presenting those concepts are anything but consistent. Using this video podcast as a resource to stay current and on trend is vital in giving my students the advantage they need to be successful beyond my classroom. I am using this in Google reader.
  • The Math Dude (Algebra 1): This is a wonderful tool for my geometry students who need to brush up on algebra and to fill in any gaps that they may experience from their previous year. This was found in iTunes as a video podcast. I like that my students can access this when they need reinforcement on a concept or just another way to look at an area that may be particularly problematic for them. This could also be used as a mini lesson to fill in weak areas in important concepts.
  • Precalculus – Fenton: I found this video podcast in iTunes. This would be a great tool for students who are absent from class. It would also give me ideas when I am looking for ways to present particular lessons. Students can use it as a review or to obtain a different perspective. One drawback is that it took a long time to download.

Also Check out: MathsMaster.org,, Math Snacks& MathtrainTV.

Some of these podcasts can be subscribed to which will feed into iTunes, others can be saved as an audio or movie file and imported into iTunes, and some are even bundled as an app. Please post others you find in the comments section along with a description and/or how they can be used.

Simpsons in the Classroom

I have used Simpson’s clips for years in my classroom as hooks, theme-based lessons, and to illustrate Mathematical concepts from fractions to Pi using Simpsons Math. Check out my Girls Just Wanna Add Sums Packet and the Simpsons Math site for even more resources on this topic/episode.

Now the Simpsons’ will be invading a Science Classroom near you. From periodic tables to Newton’s Laws, Simpson’s can provide a new perspective (or a frame of reference) on illustrating the not so concrete laws of science (e.g. Angular Momentum, Second Law of Thermodynamics, Metric System, Newton’s First & Third Law, Photon Pressure, Zinc Film, Inelastic Collision, and More…)
