Getting Started with Math By Hand Concept App

Published on 06/09/2008

Activity Overview

This App helps students build number sense skills and gain confidence at math by hand. Review how to perform algorithms for the four basic operations (Addition, Subtraction, Multiplication, and Division). A step-by-step mode emphasizes place value in the base-ten system for each algorithm. Fast mode helps student learn and review and, through the Missing Pieces game, test how well they understand the concepts. This App was programmed by Andreas Ess and Clement Vasseur.

Before the Activity

Students should have access to the TI-73 Explorer and a copy of the attached document.
