calculator, pen, and calculation notes I went through and thoroughly updated this article of mine... have you read it in the past?

Four basic principles of deeply effective math teaching

If you were asked what were the most important principles in mathematics teaching, what would you say? I wasn't really asked, but I started thinking, and came up with these basic habits or principles that can keep your math teaching on the right track.

percentages and numbers
Principle 1: Let It Make Sense
Principle 2: Remember the Goals
Principle 3: Know Your Tools
Principle 4: Living and Loving Math

3. Looking back: Ten years ago

In my newsletter 10 years ago... and still relevant...
  • Word problems in Singapore math and bar diagrams — Denise goes through a bunch of word problems from Singapore Math 3-A book, and explains both a solution based on algebraic thinking, and a solution with bar diagrams.
  • A fun "game" for math facts... or actually it is a way for children to write their own math problems using a deck of cards.

4. Why is fraction math so difficult for students?

I've updated this popular article of mine!

As many teachers and parents know, learning the various fraction operations can be difficult for many children. It's not the concept of a fraction that is difficult — it is the various OPERATIONS with fractions: addition, subtraction, multiplication, division, comparing, simplifying, etc.

And the simple reason why learning the various fraction operations proves difficult for many students is the way they are typically taught, and how many there are. Just LOOK at the amount of rules there are to learn about fractions!

5. Fraction America

Fraction America — a neat little game where you write and simplify (reduce) fractions based on the map of the United States. You can choose the number of colors to use.

6. Sassy Cents

An intriguing activity with coins.... ultimately practicing calculations with decimals (for grades 5-7).

Thanks for reading! :)
