Doing Dynamic Math & Tech Adventures

Doing Dynamic Math & Tech Adventures

Helping students to improve their problem solving ability is one of the major goals of mathematics education. The dynamic math approach is intended to help facilitate that ability. Preliminaries Students should be organized for small groups activity. Each group chooses a “captain” who will be responsible for sharing his groups decisions. Room arranged appropriately for group activity. Computer and projection device setups are ready to go. Since you want to facilitate “conversation” try calling on students rather than responding to…

Welcome to Episode One – The Road Sign Problem – Introduction

Welcome to Episode One – The Road Sign Problem – Introduction

Welcome to a new approach towards teaching and learning math with technology. I could call this approach lessons or activities but I prefer to call them adventures because I hope that each adventure will bring a new perspective on learning math with technology. This idea has been on my back burner for a long time and it’s finally ready to go. Keep in mind that this is also a learning experience for me so  I also call it a work…

Doing mathematics-the difference between deep and superficial knowledge

Doing mathematics-the difference between deep and superficial knowledge

Math education does not need reform as it equates to rearranging chairs on a sinking Titanic. We need to build a new ship. (Source) If I am advocating anything, it is only the obvious (and time-tested) idea of “learning by doing.” If I have a method, it is only to convey my love for my subject honestly, and to help inspire my students to engage in a delightful and fascinating ADVENTURE – to actually do mathematics, and to thereby gain…

Wanna do* Adventures

Wanna do* Adventures

In our investigations of children’s understanding of the mathematics of data, we identified ideas that were particularly interesting or empowering to children, and watched where they spontaneously made mathematical games and challenges for themselves. Interwoven with this process was our own deepening understanding and enjoyment of this branch of mathematics. Taking cues from children’s aesthetics as well as our own, in effect we found the “game in the math” rather than putting math in a game. And, almost by necessity,…

The Lineup: Who Doesn’t Belong and Why

The Lineup: Who Doesn’t Belong and Why

In each problem below you will find a group of four numbers or expressions. Three of the numbers belong to the same family.

Pick out the number or expression and explain why that number doesn’t belong to the family. 1. Circle the number or expression that doesn’t belong to the family and explain why. 2. Circle the number or expression…

Why do the Zeros Disappear When You Press Equal?

Why do the Zeros Disappear When You Press Equal?

by Ihor Charischak This article first appeared in CLIME Connections, Volume 7, No. 1, 1994. The big push over the past few years has been for teachers to use calculators. Unfortunately, the issue is charged because some parents have a hard time supporting teachers who use calculators before their children have learned their algorithms. Though I am a strong proponent for the use of calculators, I have to sympathize with these parents because many of the teachers that I observe have…
