Join Lumos Learning for a FREE webinar on February 07, 2013 exploring the changes on the transitional NJ ASK assessment. 

Transition to the Common Core State Standards and assessments are in progress in all New Jersey Public Schools. Between covering the standards in the classroom, adopting new curriculum, and preparing students for the updated standardized tests, it can be overwhelming. 

In this webinar, you will discover: 

• What is the NJ ASK transition for Math and Language Arts? 
• What are the NJ ASK CCSS Content Shifts? 
• What will the new test look like? 
• What are some sample questions? 

This informative webinar will take place live on February 07, 2013 at 11:00 AM EST. Register today to avoid missing out on this exciting opportunity.

Good Morning!

My name is Matthew Callison. I am a former elementary teacher working on my PhD in the School of Education at Indiana University Bloomington.

I am writing to ask for your voluntary participation in an online survey I created as part of a research study I am conducting. The purpose of this study is to learn more about elementary teachers knowledge of, and experience with, student-centered teaching approaches. My hope is that the information gathered in this study can be used to understand how we can better support elementary teachers.

If you are an elementary teacher, please consider participating in this online survey. Your experiences as an elementary teacher are invaluable in helping researchers and teacher educators learn more about how to support teachers like you in your important work.

The survey should take about 15 minutes to complete and does not collect any personal information unless you decide to leave your contact information at the end of the survey.  You can learn more about the study and begin the survey (if you choose to participate) by visiting the link below:


If you know of other elementary teachers who may wish to participate in this study, please forward this information to them.

Thank you for your time.

Dyscalculia has always seemed ill defined until I asked myself a simple question:

If a dyscalcic learned math using a spreadsheet which eliminated arithmetic as a factor, would they still have problems?  If the problems disappear you know the issue is computation.  If the problems remain, you have narrowed down the possibilities.

Let them guess the answer and give feedback --- estimation.  Guessing the answer and seeing how close they can get (cumulatively) is more like a game.  After a while they will get better and better and in fact will have learned the answers.  And what is better this can go beyond simple number facts and be expanded to two digit multiplication.

I am a third grade teacher and I love to teach math.  I do not like forcing my third graders to memorize their multiplication facts.  I spend a great deal of time explaining the meaning of multiplication and my students can figure out the products using many unique and interesting methods.  My district, and my state (NJ) however feel it is more important to just know the products and know them quickly.  Anyone have an answer so both me and the state can be happy and most importantly the students learn their multiplication facts!

In the 19th century arithmetic was the basis of the rest of mathematics. If you did not know arithmetic you could not do higher math. One of the outcomes of the 20th century was to eliminate that dependence through the use of computers. Why does 21st century Education place such emphasis on the lowest math skill, arithmetic? Is it a leftover 19th century mentality that still holds: you must start with arithmetic before you can move on.

Since arithmetic is both lower math and no longer the basis of higher math, it should have less of a place in our curriculum. Teach computation, but make arithmetic invisible when you teach the rest of math.

If I were to teach lower math, I would stress accurate estimation rather absolute precision. I want accuracy (how close to the correct) to be the criterion. If precision is essential, we would use a computer not trust the mental arithmetic of even our top student.

I would teach the rest of mathematics using a spreadsheet. It is very similar to a piece of paper except the arithmetic is done automatically.

Whether you agree or disagree I will offer any teacher interested a personalized spreadsheet series that will parallel what you are already teaching. If you are interested in exploring this, email me at drz@enabling.org.

I'm a grade 4 teacher in BC, Canada, and I'm enrolled in a post-grad. program in integrating technology in teaching. I am looking for ideas to integrate technology into math lessons (starting with whole numbers to 10 000 and addition to 10 000,) in order to better engage students in the lessons and increase their understanding of these concepts. Any ideas for sites, free programs, or lessons themselves will be appreciated. Thank you!

There is no doubt a picture is worth 1000 words. The other side of the coin is that it takes more than a 1000 words to describe one picture.

There are people who read manuals and people who read disagrams.
