The Square Abacus - An Introduction

Log in to save this to your schedule and see who's attending!

Limited Capacity seats available

This session will introduce a modified abacus and accompanying activities. We will be addressing the special features of this abacus and physically modeling major concepts of middle school math.

The Square Abacus (SA) is a modern twist on an ancient device that is educationally and developmentally appropriate and fully supportive of STEM education. The primary mission of The Square Abacus Session (TSAS) is to promote and encourage an appreciation of mathematics through the use and study of the Square Abacus™ (pat. pend.), a modified student abacus/counting frame, and it's corresponding Practicus© Activities Manual. With it's field of beads oriented in a perfect square, we will model accurate "square" numbers, angles, area models, scaling, other algebraic/geometric principles, and, all operations of whole numbers, fractions, decimals, percents, etc...

TSAS proposes solutions associated with computation skills, student achievement, technology/electronic devices, engagement, confidence, fluency and mastery.

Many abacus/counting frames are used mainly for the four operations of arithmetic, place value and other basic concepts. They vary in the arrangement and total number of beads, based on efficiency and use. The SA is capable of modeling a quality and quantity of concepts that few other manual mathematical tools can. During lessons/meetings/seminars, a "new" or different way to demonstrate a concept is often shared, sometimes involving more than one device. With the simplicity and versatility of movable graph paper, the SA is a solution-oriented manipulative for the elementary and middle school classrooms.
