In many schools in the United States, students struggling the most in mathematics at the start of high school have the worst odds of getting a qualified teacher in the subject, new research finds. Succeeding in freshman-level mathematics is critical for students to stay on track to high school graduation, with students who make poor grades in math in 8th and 9th grades more likely to leave school entirely.

Number sense, concepts, and operations word wall The purpose of the mathematics word wall is to identify words and phrases that students need to understand and use so as to make good progress in mathematics. Mathematical language is crucial to children's development of thinking. If students do not have the vocabulary to talk about math concepts and skills, they cannot make progress in understanding these areas of mathematical knowledge. They need to be familiar with mathematical vocabulary and mathematical terms to understand written and spoken instructions. See math word wall resources >

I think a lot about my math teaching. Perhaps too much. This is my outlet. I hope you find it interesting and that you’ll let me know how it’s going.

Let us climb peaks by all means, because their beauty attracts us; not because others have failed, nor because the summits stand 28000 ft above the sea…Let us approach the peaks with humility, and through finding the way to them…learn to solve their problems. Eric Shipton (1938)

There are many potential uses for social bookmarking in education. However, you may be asking yourself just what it is. Social bookmarking is a way to save, store, group, and share Internet bookmarks online. It allows you to have access to your favorite bookmarks on any computer with Internet access, so even if you are away from home, or work, you can still find and use the sites you value most. Social bookmarking sites also give you the option of joining a group of like minded people, following, or being followed by, individuals who collect similar types of bookmarks to your own. Examples of such sites include Digg, StumbleUpon, Delicious, and the focus of this article, Diigo.

1. Tardy passes.  The picture below represents all of the tardy passes I have received all semester, along with passes to the nurse and passes to assistant principals for discipline.  That stack represents a lot of lost learning time, especially when you realize that these passes are written for a lot of the same students over and over again.  If learning was really valued, there would be preventative action taken rather then just letting students be late and lose valuable learning time.

2. Announcements during class time.  For the first four years of my teaching career, I worked in a district where it was in the contract that no announcements could be made during class time other than regularly scheduled announcements during a set period.  Consequently I started teaching not knowing the agony of having my class interrupted with announcements about homecoming, meetings, or sports cancellations, and then having student attention diverted to those topics rather than what they are supposed to learn.  I always hear about cell phones being a distraction to students, but random announcements that could have waited until another time (or be made in another way) during a class can be just as much of a distraction from the real reason students are in the building. 3. Letting students talk among themselves for the last 5 minutes of class.  I am known as the strict teacher because I believe in bell-to-bell instruction.  I only have 50 minutes a day to cause understanding in my students, and I want to use all of that time.  Some students and some teachers find this unreasonable of me.4. Pulling students out of class for things that are non-learning related.  This school year alone I had students pulled out of class to talk about sports participation opportunities and to do something for an extra-curricular activity that was supposed to be done after school.  I even had a student pulled out of my class during a test because another teacher simply demanded it.  Now, I'm not against sports or extra-curricular activities; I feel they are a valuable part of a student's school experience.  It's when they start to take priority over learning that I have a problem.

Geometry is all about shapes and their properties.

Why do we do Geometry? To discover patterns, find areas, volumes, lengths and angles, and better understand the world around us.
