About Karen Greenhaus

I have been in the math education field for over 20 years. The first 15 of those as a middle and high school math teacher, 2 of those years as a district math specialist, and the last several years working as a professional development provider. I am incredibly interested and motivated by technology in education, for teachers and students, and ways to incorporate technology effectively into mathematics so that students experience and explore math in dynamic ways. I am continually trying to learn about how to improve teacher instruction so that students can learn and understand mathematics better. I have a math degree from Virginia Tech (Go Hokies!!), a Masters in Curriculum and Instruction (Math focus) from Virginia Commonwealth University and am currently ABD (all but dissertation) in Educational Technology from the College of William and Mary. I currently work for Key Curriculum Press as their Director of Education Technology Outreach - a dream job, working for the company that helped me through years of teaching...I have to pinch myself most days!

Educational Technology: What is the Cost of Free?

Posted on April 4, 2012 by Karen Greenhaus

What do you wonder? Real-world math problems are everywhere

Posted on March 21, 2012 by Karen Greenhaus

We hear this everywhere – students should be doing “real-world” math and they should be applying what they learn in math to “real-world situations.” Textbooks and math resources advertise their “real-world problem solving” experiences and “real-life math applications.” But, as … Continue reading →
