I
want to lose weight. Help me Ray!
I'm
not really qualified to help you with that. However, I can
give you a mathematical way to do it. I can't guarantee it,
but you could drop 10 pounds in 2 months. Here's what you
do.
1. Multiply the pounds you want to lose by the calories in
a pound of fat: 10 x 3500 = 35 000.
2. Divide the total by days you want to diet: 35 000
divided by 60 (days) = 583.
3. Eat that many fewer calories each day.
...and you thought it was difficult.
I
can't seem to get through all the math curriculum. What
should I cut out?
Good
question. I'm not going to suggest what outcomes aren't
important since I don't know your classroom needs, school
growth plans, or district goals. Besides, where would I
start? Traditionally, units such geometry or probability
have made it to the July Pile...But, because a numerate
student involves having a good sense of number, spatial
awareness, an understanding of patterns and relationships,
etc. it's hard to eliminate anything.
However, I can suggest a few things. To save time, move
away from teaching strands in isolation. Did you ever
notice how having taught a specific concept in October is
seemingly forgotten by February? If things are overlapped,
or revisited in different contexts, learning is more apt to
stick. Thus, you save time reteaching.
Secondly, don't assign every question, for all units, for
all lessons...etc. Just because the text has 12 questions
in the lesson doesn't mean you have to assign all 12.
Select the most important problems, questions and projects.
As well, instead of taking up all the questions when
students return the next class, simply select a few
questions at random. If students understand the material,
it should show in the way they solved the selected
questions. These two ideas could save a lot of time.
Think of it this way: If you're doing something that takes
15 minutes a day (such as marking homework with the class
the next day, or 15 minutes on ALL questions in the
lesson), then over the year, that adds up to over 2 weeks
per 15 minute block!! What could you do with numeracy in
those extra 2 weeks blocks?
When
I get to the report card, I'm stuck with piles of class
lists filled with percentages, grades, marks out of 10, 23,
100, 35, and more! Where do I start?
You
mean, "Where do you
end?".
Begin with the end in mind. If you want to keep it simple
at the end, keep it simple all the way along. Because my
school did report cards that assessed each outcome on a
4-point scale, everything I did moved immediately to the
4-point scale. It was only at the very end that I converted
the 1,2,3, and 4s into letter grades. I did that by
scanning the 1,2,3, and 4s within each subject area, and
using my professional judgment to decide the letter grade.

Do
you know any good books that my kids will love that help
them with math?
Yes
I do! Begin with anything by Greg Tang (grades K-4). My
favorite book of his is "The Grapes of Math". Kids love it
to! As well, try "Jayden's Rescue" by Vladimir Tumanov
(grades 4-7). Anything by Marilyn Burns is good,
particularly, "I Hate Math!". She manages to work in great
extensions in the back of many of her picture books. I love
"The Number Devil" too! That one is by Author Hans Magnus
Enzensberger's dry humor and sense of wonder will keep you
and your kids entranced while you learn (shhh!)
mathematical principles. Who could resist the little red
guy who calls prime numbers "prima donnas," irrational
numbers "unreasonable," and roots "rutabagas"? Not that the
number devil is without his devilish qualities. He loses
his temper when Robert looks for the easy way out of a
number puzzle or dismisses math as boring and useless.
"What do you expect?" he asks. "I'm the number devil, not
Santa Claus." (grades 4-8).
I
need some quick ideas to help enrich my math program
without breaking the bank. Help!
Okay.
Quick. Go to a fast food chain and grab a veggie burger.
Then ask for their nutritional information. Ask for 30
copies. Hand them out to your students and ask them to
create graphs, bar charts, circle graphs, pictographs, etc.
using the information on the nutritional charts. Begin by
helping students pick a question to help them focus (i.e.,
"How does the amount of protein in the breakfast meals
relate to the fat content?"). Look at the outcomes in the
IRP. Assign tasks based on student interest and ministry
outcomes. I did this in my class every year, and the
interest was VERY high! (Another idea is to grab a stack of
newspapers or magaizines and repeat the above process with
articles, stock reports, advertisements, etc.)
I've
tried using rubrics and they seem so technical to me. What
should I do? I can see how they help, but they often seem
so removed from the classroom.
One
idea that really worked for me was to work with the kids to
create well-written, effective rubrics. The most common of
them were written onto large poster paper and put on the
wall to refer to (i.e., in Language Arts: "Voice",
"Meaning", "Form", "Conventions", etc. In Math:
"Strategies", Accuracy", "Concepts", "Representation",
etc.). Once they're put into kid-language, then the whole
environment changes. Kids become co-assessors working with
you towards the same goal. Marking is thus easier, and kids
and parents know where to go next.

I
want to use some funny, yet relevant cartoons to help
reinforce ideas in my science unit. Where would I buy that?
Simply
go to Google, and type in "Science cartoons", and hit
"images" instead of "web". Scroll through the cartoons and
click on the images you want. Save them to a Word document
and copy them onto transparencies to show to the class.
Your students (many of whom are very computer savvy) can do
the same thing on more specific topics in any given subject
area. Keep in mind that many of the cartoons are
copyrighted.
I
lost my compass when I went hiking this past summer. Any
tips? I heard you were good with directions. Besides, it's
kind of a science question.
I'm
not sure who told you that I was good with directions!
That's hilarious. Anyway, there's an easy answer. Look at
your watch. Simply hold the 12 to the left. Then, turn your
hand so that the hour hand points to the sun. The spot
exactly halfway between the hour hand and the 12 is south.
It works. I tried it!
More
to come!
