Mathematical Notation and Schools – 1
Notations for negative numbers This blog entry marks the start of a series about mathematical notation and its uses in school. I intend to look in detail at aspects of the standard mathematical notations, and how these help or hinder … Continue reading
Groupings, Shopping Lists, and Vectors: The Series
This is a series on vector algebra, but it hasn’t wrapped up yet. Here are the installments as of now: Quantity – Different Kinds of Numbers: Vectors – it really all started with this post. But I didn’t know it … Continue reading
First, Do No Harm
Wouldn’t that be a great stricture for Math Education to adopt, just like medical professionals do? Whatever else you do, make sure you do no harm. You’d think that this would represent a really low standard of math education: that … Continue reading
Groupings, Shopping Lists, Vectors: part 18
If you have read earlier installments of this series – and I know it has gotten long – you may have noticed that very few of the matrices that appeared there have the same number of rows and columns. A … Continue reading

Groupings, Shopping Lists, Vectors: part 15
This post is part of a series, starting here, about models and ideas that underlie the rather abstract stuff called vectors and matrices in math textbooks. In this series, we’ve looked at shopping lists, pricing out orders, weighted averages, perspective … Continue reading

Groupings, Shopping Lists, Vectors: part 14
In the prior parts of this series, I have look at a number of problem situations from which a certain notion of grouping data and organizing data and operating on data arises straightforwardly, a way of grouping data that is … Continue reading

Groupings, Shopping Lists, Vectors: part 13
In prior posts in this series we have seen two completely different kinds of applications for the idea of matrix multiplication: in part 11 we looked at pricing out an order, and in part 12 we looked at drawing a … Continue reading
