National Coloring Book Day

National Coloring Book Day

August 2, 2016

 4 color

Today is National Coloring Book Day. http://www.coloringbookday.com/

Who does not like to color?! Did you know that coloring can be very mathematical? The Four Color Theorem, which has a rich history from the 19th C to today. Read about the history at the Mac Tutor site listed below. Then, depending upon where your students are in their mathematical journey you can use the links below to find activities for basic coloring to investigating knots, networks and topology! Enjoy!

Four Color Theorem:

The four-color theorem states that any map in a plane can be colored using four-colors in such a way that regions sharing a common boundary (other than a single point) do not share the same color.

The Top 5 Reasons for Using Manipulatives in the Classroom

Have you ever asked or said or heard a fellow educator ask or say… “Exactly what constitutes a manipulative?” “I have some of these manipulatives in my closet, but do not have a clue how to use them!” “How do I find the time to use manipluatives in the classroom when I have so much […]

Happy National National Chocolate Day: October 28thChocolate Day!

National Chocolate Day: October 28th My grandmother always said, “God was in a good mood the day He created chocolate!” I grew up thinking that chocolate was a basic food group! And, I admit, chocolate is one of my weaknesses. What does National Chocolate Day have to do with mathematics!   Well – where’s the math? […]

Functional Fluency

I just returned from NCTM Boston. What a great week! I got to catch up with a lot of old friends and made several new ones as well. My co-author, Leslie Texas, and I did a session on one of our strategies from our book series What’s My Move: A Kinesthetic Multisensory Approach to Graphing […]

Algebra I Employment Standards – 2022-2023

State Approved Hybrid Training Sponsored by the Tennessee Department of Education The State of Tennessee has provided various paths for qualified middle school teachers to teach Algebra I/Integrated Math I for high school credit. The various paths are described at https://www.tn.gov/education/licensing/educator-licensure/licensed-educators.html.  The purpose of the trainings offered here is to provide the pedagogical and content […]

Putting the “A” in STEAM

Are you looking for a summer workshop for your K-12 students? In July, I will be hosting an art/writing workshop for students K-12. We will be focusing on Putting the “A” in STEAM.  This 6-day enrichment workshop will focus around the arts and humanities. Students will create and begin to use a combined art journal […]

NCTM, San Francisco

My colleagues and I really enjoyed your presentation at NCTM.  We have already convinced our principal to pre-order us copies of your new book, but we would also like 4 class sets of the pyramids. 

Many presentations talked about problem solving and the benefits of giving students higher level thinking problems, but yours was the only one that really told us how to teach it and scaffold it for students, rather than just modeling what problem-solving looks likes.  Thanks.
