Look for patterns, symmetry and other math principles when you are on a field trip

When you go to a museum, look for patterns.  Our students are headed to the Morikami Museum in Boca Raton, Fla., and we hope this announcement will bring new focus on math in the real world.

"Students are encouraged to bring photos to show Mr. Mac because he visited the Morikami 24 years ago and he'd like to see what you find is interesting.  He'd like to ask you to describe the patterns and the math that you see in the grounds of the museum.   This offer is for all participants in the field trip, even teachers, and even if the students are not in my class.  Mr. Mac wants to encourage the hunting for patterns.  He has a blog and he'll post their photos if they want to show them to students in other schools."

We recommend these videos and websites (suggestions from my students)

What is the power of one person? One person can recommend a video or website and then hundreds of people can click. Let's increase our "Net" impact by sharing the links of websites and videos that inspire us.

A wonderful violin... recommended by Serena Color World Origin (recommended by Colon)

Sticy ninja Academy (a cool math game)

Children of the Night (channel: duo Cartoonist)

April suggests GoPro: Fireman Save a Kitten on the GoProCamera channel

We have shared this list in the hope that students and teachers in other schools can visit these sites and videos (and we invite you to recommend some videos for us to look at, too). This list was sent to Jodie Woodruff at, an excellent school in Providence, R.I. Send suggestions to Steve at

We also invite you to see some SAT math prep at

Please go to "people to people" on google (a suggestion by Serena)

Here are some more suggestions Cool math game

4 seasons hotel in BoraBora

Halloween horror nights videos at Sharp Productions

We also clicked on my video about Big Picture school

And we Looked at the Met Center

We looked up the Entrepreneur Center at

We look forward to seeing the suggestions by Jodie's students (and others)

How to make $20 per month (or more) with your own Youtube account
I'm a teacher of math. I think it is a good idea to practice maing money because then students will get interested in math. I have a youtube account that is linked to adsense. That's the key.

1. Get parental approval.

2. Set up a gmail account.

3. set up a blog so you can point people toward your youtube account.

4. set up a youtube account to receive your movies

5. set up adsense by foloowing the steps on eHow at

If you have questions, please write to me at or you can text me at (954) 646 8246. Good luck.

Cazadores Del Red Tyler and Juliano have identified several MULTIPLICATION PRACTICE activities

The National Council for Teachers of Math have a site called "Illuminations" with activities to grow the brain power.

CLICK HERE for Illuminations

For Grades 6-8

You are invited to visit the following locations for additional preparation for rapid math calculations.

we also recommend TYPING PRACTICE like

These sites were found by Tyler and Juliano, who are "hunters on the Internet" (cazador del Red).

Sasha and Franchesca found 
Lemonade Stand
Crazy Taxi
Coffee Shop  

I recommend only these activities on Hoodamath and because we are looking only for math games that involve MENTAL MATH calculations.   

Learning new instructions will increase the blood flow to the brain, but after the instructions are learned, a skill game is usually just a way to relax.  To build new synapses (connections), please look for multiplication and division games.

Special thanks to Marcos for his work with Mr. R. and organizing the videos and photos for the dance department.

"WEIGHT" and "MASS" appear in the Critical Thinking about Math Class.... with a comment from a teacher (from 1974).

The mass / weight exercise  bubbled up some memories of this work in my high school.    so I wrote to my teacher from 35 years ago.   HE WROTE BACK...
(LESSON:  keep in touch with your teachers)

I thought it might be fun for our students to see that even high school graduates have a memory for this important work....

Hi Steve,
  The difference between weight and mass is NOT easy since, in everyday language, there is a misuse of the words.  One says my weight is 65 kgs.  The kg is a unit of mass and weight is a force - the pull of the earth on a mass.  the other classic example is that one will hear there is no more power when one really should be saying there is no more energy (electrical).  Anyway the easiest way to differentiate between mass and weight is this.  The person in orbit in the ISS is weightless - the reason for this is also quite hard to understand/explain - but it would be highly embarrassing to be massless since then the person just would not be!!!!  There would be no matter/material to make up the person.  No one minds being weightless but do they heck want to be massless, i.e. non-existent?!!  I am impressed that Mr McCrea remembered my Physics lessons!
Kindest regards and I hope my little idea helps.
Tony Hyde.

The Altar of the Non Working Computer is a silly way to attract students to make recommendations.

Erik Erikson states that children need to feel "industrious" and they need to feel that they are contributing to the community.

Students can help by clicking on useful websites and by recommending sites.

See the program.

If you want to submit suggestions, write to

Thank you.

Here is a quote from WIKIPEDIA about Erikson's stages

Competence: Industry vs. Inferiority (Latency, 5-12 years

  • Existential Question: Can I Make it in the World of People and Things?
The aim to bring a productive situation to completion gradually supersedes the whims and wishes of play. The fundamentals of technology are developed. To lose the hope of such "industrious" association may pull the child back to the more isolated, less conscious familial rivalry of the Oedipal time.
"Children at this age are becoming more aware of themselves as individuals." They work hard at "being responsible, being good and doing it right." They are now more reasonable to share and cooperate. Allen and Marotz (2003) [7] also list some perceptual cognitive developmental traits specific for this age group. Children grasp the concepts of space and time in more logical, practical ways. They gain a better understanding of cause and effect, and of calendar time. At this stage, children are eager to learn and accomplish more complex skills: reading, writing, telling time. They also get to form moral values, recognize cultural and individual differences and are able to manage most of their personal needs and grooming with minimal assistance.[7] At this stage, children might express their independence by talking back and being disobedient and rebellious.
Erikson viewed the elementary school years as critical for the development of self-confidence. Ideally, elementary school provides many opportunities for children to achieve the recognition of teachers, parents and peers by producing things- drawing pictures, solving addition problems, writing sentences, and so on. If children are encouraged to make and do things and are then praised for their accomplishments, they begin to demonstrate industry by being diligent, persevering at tasks until completed, and putting work before pleasure. If children are instead ridiculed or punished for their efforts or if they find they are incapable of meeting their teachers' and parents' expectations, they develop feelings of inferiority about their capabilities.[1]
At this age, children start recognizing their special talents and continue to discover interests as their education improves. They may begin to choose to do more activities to pursue that interest, such as joining a sport if they know they have athletic ability, or joining the band if they are good at music. If not allowed to discover own talents in their own time, they will develop a sense of lack of motivation, low self-esteem, and lethargy. They may become "couch potatoes" if they are not allowed to develop interests.

Lateral Thinking Problems -- let's expand our minds by looking at situations in a new way

You can prepare for questions in school by looking at the answers. 

Yes, it's nice to stretch your mind by trying to figure out the solution, but it's also fun to LOOK FOR PATTERNS.

You can also find some of these puzzles on youtube.

How about listening to an interview with the great puzzle master Edward deBono?
