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.

I'm really touched that you "stole" my mnemonic device! It puts a smile on my face to see my idea in your compilation. Sending you love from one math educator to another as we keep the faith during these exceptional times!!

Hello! I really enjoyed that you had multiple engaging activities that work for one topic. I generally find myself coming up with only one "fun" activity for each topic. This can get a bit boring because I feel like I am just giving worksheets because I want them to have a general idea of the topic before I set them out on their own. I really wish I had read this a couple weeks ago when we were covering logarithms. But these games seem like they could be adapted to fit whatever topic you are covering. This makes them more flexible than other games I have played in class. It also means that we could play these games throughout the year and get a bit of a learning curve.
