Goodies for teachers and all

Just a few items of interest:

1) Math Goodies CD from has been updated earlier this year; I got to see it, and updated my review of the CD. It's full of good math lessons with interactive exercises, printable worksheets, crossword puzzles and more.

2) I've added a free online equation editor to my site. This would be most useful for teachers or others who write math content and need images for complex symbols and math expressions.

3) Those of us who use math a lot might also enjoy a free calculator/graphing program called SpeQ Mathematics. You can type complex expressions into it, define variables to be used in later calculations, and make plots.

Mnemonic helps for multiplication tables?

...regarding my third grader. We are still slogging through learning the times tables. To liven it up, I decided to order Times Tales (I ordered the deluxe version that includes division as well).

I have read different opinions about using mnemonic devices to learn math facts. Some say that mnemonic devices actually slow the student down, and one even went as far to say it was like counting on fingers. I don't want to use Times Tales if it's going to slow her down, and I do want to make sure she knows her math facts cold.

I, myself, remember I didn't know 8x8=64 in seventh grade, and I just figured it in my head, 8+8=16, 16+16=32, 32+32=64 -- 8x8=64. I did this until I realized how slow I was and decided to commit the facts I didn't know to memory. What do you think about Times Tales and other "helps" for math facts?

Mnemonic helps in themselves are not bad. We use them all the time, in everyday life situations. You have a phone number, you divide it to 2-…

Performing well below grade level

I am leading a training next week on how to introduce grade level concepts/standards when the students are performing well below grade level, and I am sure that math is going to be an issue. Any suggestions?

These are my 2 cents on teaching under-performing students.

Let's imagine we have an 8th grader performing on 3rd grade perhaps.

I would dismiss for starters geometry and measuring topics, and concentrate on this train of topics, in THIS ORDER:


... the goal being to cover the basic arithmetic up to pre-algebra.

Think of mathematics as a building. You need to have the foundation building blocks before you can go forward.

Maybe the child stopped understanding the math on 2nd grade or 3rd. We need to find the exact point after which he has not understood everything.

You can gauge this by the way by asking the child simple questions such as,

I give you an addition 8 + 2 = 10, you give me a subtraction sentence (1st grade knowle…

New games website

Again! Games sites certainly abound on the internet.
I didn't try all the games but I liked the tangram puzzle game. - Mathematics

On their home page are links to other school subjects as well.

The good side of manipulatives

Update: read also Mama Squirrel's excellent blogpost on the issue; basically there is probably a balance in this, as in everything.

If you haven't, go pay a visit to the National Library of Virtual Manipulatives.

Lots of good stuff there!

So, why would I suddenly turn around and praise manipulatives, if I just mentioned how they're not the "ultimate thing" in math education?

It's just one of those things that can be good, if used right, in its rightful place.

Manipulatives do help students to understand concepts, initially, on a concrete level. But they shouldn't stop there. Kids need to learn to make generalizations. That is where the power of mathematics is.

For example, maybe you'd use The Base Blocks Addition to illustrate the concept of "carrying" to tens and hundreds (or "trading") in addition.

Once the student understands that, they should be able to translate their knowledge into bigger and smaller place values (including decima…
