1. Ring a Bell Numbers – Fun Math in the Classroom
Ring a Bell Numbers is one of my favorite game-type
activities in the classroom since it allows numbers from
outside the classroom to enter my students’ lives in a fun,
engaging way. Here are some reasons to use this activity:
Excellent way to reinforce the importance of numbers
• Shows numbers as part of common knowledge
• Relates mathematics to the real world
•
Great way to review vocabulary
•
Good for class game by teams
•
Engages all levels of learners
•

2. Math Made Fun – a Video Series for Math Mavens
and Future Math Mavens
On my mathvideouniversity site on youtube, I’ve begun a series of videos intended to
bring FUN into the math classroom while still teaching sound mathematics. My
coauthor, Brad Fulton, and I have created literally thousands of pages of activities on
Microsoft Word and PowerPoint that are currently residing on our hard drives. Prior to
making these videos, the only people who were able to take advantage of these
resources were our students and the folks who attended our workshops/conferences or
bought our books and DVDs.
We want to make this exciting mathematics more available to a wider audience, and
have decided that creating online videos will do the trick! Our goal is to create videos of 5
– 10 minute duration that are tightly focused around one topic that show some
fascinating aspects of mathematics. Here are some ways/reasons these videos can
be used:

2. Math Made Fun – a Video Series for Math Mavens
and Future Math Mavens
It’s possible to do things on a video that are not able to be done in a classroom
Students can watch these videos any time – pause/rewind any part of video
Parents/tutors can watch with students to give help as needed
1. They allow parents to keep in contact with what’s going on in the classroom
2. A new model: Instruction can happen outside the classroom & tutoring can happen
inside the classroom
3. Students need to see that education/training is available to suit their schedules
4. Allows educators to view video to improve instructional strategies
5. Can be used for teacher inservice training at workshops/faculty meetings
6. Can be used for individual teacher enrichment/education
7. Can showcase teachers at their best – without having to deal with daily issues
8. And lastly, a substitute can show the video so that instruction can take place in a
teacher’s absence

3. Video – Standardized Test Strategy – Working
Backwards
The Standardized Test Strategy – Working Backwards
video shares one approach I take in class with students
when explaining how to do well on standardized tests. It’s
helpful to have the correct answer as one of the possible
answers given on the test. It’s even nicer when you have
some strategies to make it even easier to score better!

5. Video – Sum Equals Product Puzzle – Part 1
Here’s a puzzle from the California Math Communicator,
the quarterly math journal for California’s math teachers
from the California Math Council.
The Sum Equals Product Puzzle asks the question, “Can
you find two positive integers whose sum equals their
product?” Bill Lombard shares this problem and shows
several extensions of this puzzle about number sense.
Part 2, the next video in this series, will show the solution,
Bill’s method of solving, extensions, the generalization, and
some pedagogy of teaching problem solving in the math
classroom.

6. Reverse the Math Puzzle Using 2, 3, and 4
I’ve just posted a new video at my mathvideouniversity site on youtube called
Reverse the Math Puzzle Using 2, 3, and 4. This puzzle uses the numbers 2,
3, and 4, along with standard operational symbols of mathematics to create the
numbers 1 – 10.
The reason it’s called Reverse the Math is that the numbers from 1 – 10 are
the target numbers, or essentially the answers to problems that must be
created; so students and puzzle enthusiasts are given the answers, but must
come up with problems that have the answers from 1 – 10.
Not only is this a great puzzle that builds number sense, it also reinforces a
great deal of number properties and provides examples of algebra concepts
in a fun way. You can find solutions using exponents, factorials, and square
roots, and in most cases there are a number of different ways to express
numbers using the given “ingredients.” I’ve used this type of puzzle for years,
often spending a week on this as warmups or part of homework. Each day I
change the ingredients and watch students’ number sense and enthusiasm
grow.

7. GeoGebra Prim – a Simpler Version of GeoGebra for Younger Students
The developers of GeoGebra have created a version of the algebra/geometry/creative math software
for younger students. This “slimmed down” version has much of the capabilities of its bigger cousin,
but with a simplified interface. Users of GeoGebra will find no difficulty with this version, but for new
users it is somewhat easier since there are no dropdown icon menus. There are some default
options that simplify drawing, and only the most common geometry constructions are available from
this menu.
Here’s the download site for this new addition/edition of GeoGebra – making this creative, intuitive
software easier to use for younger minds:
http://www.geogebra.org/webstart/4.0/GeoGebraPrim.jnlp
Some of the features:
* Restricted set of Tools available
* All available Tools visible at once
* Larger Font size
* Larger / Thicker Objects
* Just the Graphics View showing
* Easier to select objects
* Labeling of objects disabled
* Angles always between 0° and 180° by default
My verdict after playing with this new version: It’s a sure winner, and I’m glad to see that younger
people will be better able to develop their mathematical minds with GeoGra Prim.

8. Mr. L’s YouTube KenKen Video
I got an email from YouTube a few days ago asking if I was interested in YouTube’s Partnership
Program. This program allows video makers the opportunity to place ads next to their videos and
receive a share of the revenue.
I was surprised at this, so I visited my KenKen video, KenKen 4×4 Introduction and Strategy, and
found out that it’s been watched over 13,000 times as of this date (mid-Dec 2010). That’s pretty cool
for a math/puzzle video. It’s nice to see so many people interested in puzzles, especially one that
is so math oriented. So I guess I’ll make some more vids showing how to use puzzles in and out of
the classroom to improve logical and mathematical thinking.

9. Video – Standardized Test Strategy –
Eliminate Impossible Answers
The Standardized Test Strategy –
Eliminate Impossible Answers video shares the approach I take in class with students when explaining
how to do well on standardized tests. There’s a lot of good thinking that can be found in multiple
choice tests, and I stress with students that they want to be “smart test-takers” when doing these
tests. I don’t give answers here, but point students in the right direction so they don’t make obvious
mistakes.

10. Pyramid Math – a Video Introduction to the Number Sense Development Activity
One of the most popular activities from the Teacher to Teacher Press book Number Sense is Pyramid
Math. This creative practice activity facilitates discovery of number patterns and develops number
sense. The activity works great with both positive and negative numbers and decimals and
fractions. Because it can be designed to be self-checking, it is easy for the teacher and engaging for
the students. Watch Bill as he gives an intro to this wonderful activity. It can be played in HD (720p) for
full-screen use in classrooms with projectors.

13b. Knights Tour 5x5
Knights Tour 5x5 is a motivating activity/puzzle that works with both over and under achievers,
promotes critical thinking and strategy, and is a great introduction to chess. It has multiple solutions, is
self-assessing, and can be extended to an 8×8 grid involving magic squares.

20. Pendulum Waves
Fifteen uncoupled simple pendulums of monotonically increasing
lengths dance together to produce visual traveling waves, standing
waves, beating, and (seemingly) random motion.
The period of one complete cycle of the dance is 60 seconds. The
length of the longest pendulum has been adjusted so that it executes
51 oscillations in this 60 second period. The length of each successive
shorter pendulum is carefully adjusted so that it executes one additional
oscillation in this period. Thus, the 15th pendulum (shortest) undergoes
65 oscillations.
