Check out these hands-on and interactive activities for introducing logarithms. Some of my students’ favorite logarithm activities include log war, logarithm bingo, and log speed dating.

## Logarithm Speed Dating Activity

I learned about logarithm speed dating from Amy Gruen who refers to it as “Super Speedy Quiztastic Fun.” I printed off Amy’s log flash cards. There were two levels of questions, so I printed them on two colors of card stock and laminated them.

## Logarithm Bingo Activity

I learned about this logarithm bingo activity (MATHO) after a student asked if we could play log bingo after playing a game of log war. I had to do some googling to see if it existed. It did, and it was a huge hit with my students!

## Log War Activity for Practicing Logarithms

To give my Algebra 2 students much-needed practice with logarithms, we played log war. I printed and laminated decks of logarithm war cards. There are many different sets of log cards available online to download. I chose a deck created by Lisa Henry.

## Converting Between Exponential and Logarithmic Form Foldable

I created this converting between exponential form and logarithmic form foldable for my Algebra 2 students to glue in their interactive notebooks.

## Logarithm Tarsia Puzzle Activity

I used this logarithm tarsia puzzle (also know as a square puzzle) with my Algebra 2 students. We glued our finished results in our Algebra 2 interactive notebooks.

## Logarithms Foldable

Today I’m sharing a logarithms foldable I created for my students to glue in their algebra interactive notebooks. I also share a helpful log loop trick.

## Swap Two – A Logarithms Task

Harry O’Malley shares a lovely logarithms task called Swap Two. Swap the position of two of the digits to make an expression with: 1) the highest value or 2) the lowest value.

## Earthquakes and Explosions – a Logarithms Problem Based Assessment (PBA)

Several years ago, a summer workshop I was part of was centered around learning to write problem based assessments for math class. The group I was in was tasked with writing an Algebra 2 level PBA. My group chose to write our assessment over logarithms. Here’s the Logarithms Problem Based Assessment that my group came up with.
