| Magnificent Mysterious Monarch Migration |
Not only are Monarch butterflies striking to look at, but they are the champion distance travelers of the butterfly world. During the late summer and fall, millions of Monarchs spend up to ten weeks migrating as many as three thousand miles to warm winter roosting spots! Monarch butterflies that live west of the Rocky Mountains in the United States and Canada migrate to the California coast. Most Monarchs that live east of the Rockies fly to the mountains of the Mexican state of Michoacan.
Monarch migration is full of mystery and wonder. The butterflies that migrate to their winter homes are not the same butterflies that spent their winter in California and Mexico the previous year. It is the great-grandchildren and great-great-grandchildren that make the journey! The adults that leave their winter homes lay eggs during their spring migration. The eggs hatch, caterpillars emerge, the caterpillars feed and form chrysalises, and from the chrysalises, adults emerge and continue the northward migration. This cycle occurs several more times during the summer, until after three or four generations, the descendents of the original overwintering butterflies are ready to make their fall journey to warm winter roosts.
No one really knows how Monarchs find their way back to the winter roosts. (The offspring of other migratory animals, like whales and caribou, have parents to guide them.) Scientists have offered the following answers to questions about how the butterflies know it is time to migrate and which direction they must travel:
- Shorter hours of daylight and cooler temperatures tell the butterflies when to begin their fall migration.
- Monarchs use a combination of their internal body clocks and the sun to figure out the direction they need to migrate.
But knowing “when” and “in which direction” doesn’t tell us how they “navigate” (how they find the exact location of where their great-grandparents and great-great-grandparents spent the winter). The question of “navigation” remains a mystery!
People have been counting and tagging Monarchs for many years to help solve this mystery. “Tagging” refers to attaching a tiny tag to a butterfly’s wing to help identify individuals when they are caught. Suppose your teacher gives you the following information:
- On average, 60 Monarchs will migrate past your school each hour for the next 30 days.
- The migration will last 8 hours each day.
- Your class will catch and tag Monarchs for 2 hours each day
- In all, your class will tag 1% of the Monarchs that migrate past your school during the time your class is catching and tagging Monarchs
Estimate how many Monarchs will migrate past your school over the next 30 days. Of these, how many Monarch butterflies will your class tag?

Fact or Opinion
Posted: 2010-04-15
Hello All-
My name is Paul McKinney and I am very pleased to be a regular contributor to this new and informative blog site.
First let me tell you a little bit about who I am and the experiences I bring to this site. I always find it important to identify with those I share ideas, opinions and most importantly research. This is my 42nd year in the field of education. Notice that I did not identify education as a profession.Along the way I will explain my reasoning for this statement.
I started teaching in 1968 in a very small community in upstate NY.And for the next 22+ years taught in the public schools around Central New York. I must say that my favorite teaching experience was when I taught Kindergarten for 5 years. I learned more about teaching from teaching these little munchkins, than I did from taking any methodology class in undergraduate or graduate school. I taught all grade levels through 5th grade, special education through high school, and was an Assistant Director of Special Education for 5 years in charge of Curriculum and Instruction representing nine different school districts. For the past 20 years, I have been consultant trainer for SRA, a Project Director of Project Follow Through, and owner and principal in two major staff development companies. I am presently Vice President and partner in Educational Resources, Inc. (ERI) (www.erigroup.us) And I am proud to say that for 40 of those years I have been associated with all of the powerful instructional programs that come under the "umbrella" called Direct Instruction. OK, there you have it. I also need you to know as I write on this blog, I promise to always delineate between fact and my opinion or experience.
Earlier, I made the statement that Education is still a field and not a profession. I say that after the accumulation of 42 years of working hard, reading lots, studying diligently, and observing always. We are in fact a fickle profession (OPINION). My exp....

Welcome to the New MathMastery
Posted: 2010-04-15
The MathMastery team is excited about the launch of its new web site. On the site you will find a wealth of math and science content. Our blogs will be hosted Paul McKinney and his team from Education Resources Incorporated, Sky Lamont, a home schooling mom, and myself. In this first posting I want to introduce Paul and Sky and set the stage for future interactions one can expect.
Paul McKinney, Vice-President of Educational Resources, Inc. (ERI) was recently notified that he was unanimously selected by the Board of Directors of ADI to receive this year's Life Time Achievement Award. The award comes as a result of a 40-year commitment to Direct Instruction. Paul started his teaching career in 1968 in Phoenix, New York. He has spent his entire career, teaching, training, supervising and promoting effective teaching and D.I. In 1989, Paul left public education to form and become President of J/P Associates, Inc. Then again in 1999, along with his partners Dr. Molly Blakely and Ed Schaefer, formed Educational Resources, Inc. a professional staff development company. ERI presently partners with school districts across the United States and abroad. Paul holds a B.A. and an M. S in Early Childhood Education from the State University College at Oswego and a C.A.S from Syracuse University in Educational Administration. Paul will receive his award at the annual ADI conference in Eugene Oregon in late July.
MathMastery online subscribers already know Paul. He is the narrator on many of the math and science videos. Check out Changing the Sides of an Equation video in the Absolute Value and Problem Solving tutorial in the Equations, Roots and Exponents! See how many more times you can find Paul as a narrator on MathMastery. Send us your answer. The winner(s) will get three months free subscription to MyMasteryNetwork, MathMastery’s online math subscription.
I look forward to Paul’s contributions to the MathMastery blog on effective teach....

The Power of Positive Association
Posted: 2010-04-15
One
of the basic challenges a homes schooling parent faces is resistance from their
child/children towards their daily lessons. I'm sure there are a couple of
parents out there right now who know exactly what I mean -the moaning, the sad
faces, the snails crawl paces at which the kids do their activities - you know,
the pain we parents go through.
I'm
a life coach, one thing I can tell you is that sometimes my adult clients act
the same way. Take for instance a client who wants to lose weight. Making
healthy eating choices and exercise are not always easy - or are they? It
really depends on the perception they associate with having to do those
activities. If they have positive associations, then their exercise routine
flows even when they're pushing through tremendous resistance like lifting
weights. If while lifting, they co....
