Logarithms Lesson Starters and Online Activities

There are 366 different Starters of The Day, many to choose from. You will find in the left column below some starters on the topic of Logarithms. In the right column below are links to related online activities, videos and teacher resources. A lesson starter does not have to be on the same topic as the main part of the lesson or the topic of the previous lesson. It is often very useful to revise or explore other concepts by using a starter based on a totally different area of Mathematics. Main Page
Logarithms Starters: Exponential Error: This lesson starter presents a number of statements about indices and pupils are asked if they can spot the mistake. Small images of these Starters :: Index of Starters Logarithms Advanced Starters: Chris Smith's 688th Puzzle: Simplify the sequence of logarithms Log Perfection: Determine whether the given statements containing logarithms are true or false Logarithm Equation: Solve an equation containing logarithms with different bases Product of Indices: Find the product of the unknown indices that feature in two equations Index of Advanced Starters Suggested Indices True False Arrange the given statements involving indices to show whether they are true or false. The short web address is: Transum.org/go/?to=indicestrue Curriculum for Logarithms: Years 12 and 13 Pupils should be taught to know and use the definition of log_ax as the inverse of a^x, where a is positive, not equal to 1 and x ≥ 0.Know and use the function ln x and its graph. Know and use ln x as the inverse function of e^x more... Pupils should be taught to understand and use the laws of logarithms: log_ax + log_ay = log_a(xy) log_ax − log_ay = log_a(x÷y) klog_ax = log_ax^k (including, for example,k = −1 and k = −½) more... Pupils should be taught to Solve equations of the form a^x = b more... Pupils should be taught to use logarithmic graphs to estimate parameters in relationships of the form y = axⁿ and y = kb^x, given data for x and y more... International Baccalaureate See the Number and Algebra sub-topics, syllabus statements, exam-style questions and learning resources for the IB AA course here. Exam-Style Questions: There are almost a thousand exam-style questions unique to the Transum website.

All in all your resources provoked discussion and the students had a lot of fun."	Notes: Older teachers will remember their school days, before calculators were widely available, using logarithms to perform difficult multiplication and division calculations. Nowadays logarithms, or logs as they are more commonly known, are studied as part of an A Level and International Baccalaureate course and are seen as being useful for solving certain exponential equations. Basically a logarithm is the inverse function to exponentiation. The person who is most commonly credited with the invention of logarithms is the British mathematician John Napier Logarithms Activities: Indices True False: Arrange the given statements involving indices to show whether they are true or false. Logarithms: Self-marking exercises on evaluating logarithms and using them to solve equations. Alternatively, for the more advanced student, there is an ever-growing collection of Exam-Style Questions with worked solutions on the topic of Logarithms. Logarithms Videos: Logarithms Introduction: A basic introduction to the concept of logarithms from the Khan Academy Log Tables: Logarithms and log tables - what Transum used before calculators!
