I recently got a question concerning a 3rd grader who has always had difficulty with number memorization and counts on her fingers. Mom is planning to start Math Mammoth grade 2 with her.

Her question is, "Is it okay to let her use a 100 chart while going through the program and completing the assignments? We will also continue to practice math facts with flash cards, etc."

Licensed with CC BY-NC-ND 2.0 I've written some thoughts about this issue... I feel it is fairly comprehensive article, and hopefully helpful! Let me know what you think.

Here's the outline of the article:

The problem Have you ever noticed this kind of "recipe" for math lessons in many math books?

LESSON X
Explanation and examples.
Numerical exercises.
A few word problems.
In other words, the word problems are usually in the END of the lesson, and just a few. But worse... if the lesson is about topic X, then the word problems are usually about the topic X too!

Children might be learning about multi-digit multiplication, or subtraction, or dividing decimals. After the calculation exercises come…
