Today in Algebra 2, we did my version of Logarithm War. For the uninitiated,

here is the post from Kate Nowak with her version. With my Algebra 2 students, my goal was to have them practice solving for x in a logarithmic equation. If you've read my blog as of late, I have been very frustrated with their lack of arithmetic skills, especially with regards to powers lately. What I did was have them get into pairs and grab whiteboards. There are 36 cards (so if I had an odd number of students, there could be a group of 3 and still divide the piles into equal numbers) and they were divide the cards into equal piles. Each student was to work out their problem and the person with the highest answer got the cards. If they were equal, they were to lay down another card face down and then a 3rd card face up, which they were to work out to determine the winner. Winner of each pair at the end of the period got a blow pop.

Here are the cards I used:

Your way to describe log are new and fresh,these type of techniques make maths easy,I want to discuss a simple definition of calculus as-Calculus is the study of how the things change with keeping the main focus on:

1.Rate of change

2.Accumulation

Calculus is divided into two categories that is differential calculus (also known as rate of change) and integral calculus (also known as accumulation) and fundamental theorem of calculus connects both of them.

Thank you for the mention, Lisa! I know that motivation is especially difficult this time of year. Great job keeping your students focused until the end! Amy

P.S. I forgot to mention that I like the way you varied the location of the X in your cards. I also like that you had the students verify their work on white boards, hopefully reducing the number of passive participants. Nicely done!

I used your cards in my Honors Algebra II class this week. The students loved the activity and I think the practice really helped them!! Thanks.
