SHARP Calculator Zipped File

https://www.scoilnet.ieuploads/resources/29365/29101.zip Added: 26 Mar 2019 Contributor: PDST Resource type:

Calculators are an invaluable tool when doing maths. Students need to become proficient at using their calculator. An important part of this process is learning how a calculator carries out certain calculations. While calculators are an important tool for doing maths, students still need to understand how to do calculations without a calculator and to understand if the results of a calculation are reasonable or not.
Here you will find instructional videos, PowerPoints, and activities to help students to learn how to use their SHARP calculator.
