QLD (Nspire): Logos Arithmos

by Texas Instruments


The main aim of this activity is to provide students with a better conceptual understanding of logarithms. This understanding is based on the original idea of providing a 'linear' way of performing multiplication. A digital slide rule and graphs help provide this understanding. 


  • Logarithm
  • Exponential
  • Linear and non-Linear

About the Lesson

Students use a combination of a virtual slide rule, approximations and graphs to help understand logarithms. Students use the approximation tools to solve problems where the unknown is in the index. A virtual slide rule helps connect the notion of addition with logarithms and finally typical calculations involving logarithms.
