A Graphing Calculator for Less than $1.00!

The PI83 Graphing Calculator is an iPhone app designed to replace the Texas Instruments TI83 graphing calculator. With over 100 math functions, it makes expensive and bulky graphing calculators a thing of the past. One of 10 “Best Apps” from eSchool News. With over 100 math functions, the graphing calculator is a clone of the TI-83 without the $70 price tag!

If your students already have smartphones, this app is a cost effective solution to their calculator needs!

Does anyone know of a great graphing calculator app for the Android platform?

The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.

Here’s an excerpt:

A New York City subway train holds 1,200 people. This blog was viewed about 5,000 times in 2011. If it were a NYC subway train, it would take about 4 trips to carry that many people.

The Ruler Game

Occaisonally I get the opportunity to work with CTE teachers on imbedding higher-level mathematics into their content. Their biggest complaint is that students do not know how to read a ruler.

A colleague of mine (Leslie Carson of SREB) told me about a CTE teacher who made the claim that every student knows how to read a ruler by the second day of his class. To accomplish this he has a policy that students will not be able to begin working in the “lab” until they score 1,000 points on The Ruler Game (at various levels). The Ruler Game is a great little online applet for students of all ages.

By implementing this policy, every student except for one earned the necessary points to enter the lab by the end of the first day of class. The one exception earned his 1,000 points within the first 5 minutes of day two!

Have You “Flipped” Your Math Classroom Today?

Have you “flipped” your math classroom? Students in a flipped classroom (sometimes referred to as reverse instruction) view the “content delivery” / lecture before class. Students and teachers then use their valuable class time to explore and to practice mathematical ideas and concepts. In the flipped classroom the teacher truly becomes a facilitator as students are able to work in groups and take charge of their learning. Flipping the classroom also allows for differentiation and give the teacher time to work with students who are struggling (either individually or in small groups).

Parents are quickly becoming fans of the flipped classroom. How many times have parents told you that they don’t understand their child’s math well enough to help them? Now parents can view their child’s “homework” with them…allowing learning to become a family affair!

Here are a few articles and blog posts on the flipped classroom:

Now that you have decided to flip your math class, you will need some video resources that will become a part of your content delivery. Here are three of my favorites:

  • Khan Academy – This is the mother lode of brief instructional math videos. Here you will find everything from basic addition to Partial Derivatives of Vector-Valued
    Functions. There are also many non-math subjects on Khan Academy so be sure to share with your non-math colleagues!
  • The Math Dude – Mike DeGraba IS the Math Dude and he has produced a series of engaging math video clips that follow the Montgomery County Public School’s (MD) Algebra 1 curriculum.
  • TED Ideas Worth Spreading – There are a few nice math videos here and many wonderful, inspirational and motivational videos in this collection. This is another good one to share with your non-math Brethren!

So I have to ask (POLL):

Can’t Go Wrong with Harry Wong!

Wow! That was a really short summer! I sent my kids and husband (an 8th grade teacher) back to school this week and I am now getting back into the swing of my work.

When I was a classroom teacher, one of my favorite resources was The First Days of School: How to Be an Effective Teacher by Harry K. Wong. It does not matter if this will be your first or 31st year of teaching or if you teach kindergardeners or high school seniors–this book is full of great ideas that will make for a smooth year and improved student achievement and behavior!

Teachers.net also publishes a free monthly column by Mr. Wong and his wife Rosemary.

Good luck and I hope all of you have a fantastic year!
