## Swap Two – A Logarithms Task

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

## Exponents Chart (Powers of 2 to 9)

I created this exponents chart that lists the first 8 powers of each of the numbers from 2 to 9 for my students. I thought it might also be of use to use and your students. We started reviewing exponent rules in Pre-Calculus today. We’re doing this in preparation for our exponentials/logarithms unit which is …

## 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 …

## Amy Gruen’s Exponent Puzzles

I’m really looking forward to using Amy Gruen’s Exponent Puzzles in my Algebra 2 class this year. I’ve already printed off a copy so I don’t forget to use them! These exponent puzzles are going to make the perfect introduction to logarithms!

## 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. I originally found the file for this logarithm puzzle online, but it seems like it has been taken down. I am uploading it below. If this is …

## The Case of the Cooling Corpse Task

I got a chance to work through the case of the cooling corpse task at a common core workshop that I attended (OGAP) during the summer of 2013. This is a fun way to bring some creativity into the classroom and explore Newton’s Law of Cooling. I am blogging about the activities that we worked …

## Change of Base Formula Notes

I created this page of change of base formula notes for my Algebra 2 students to glue in their interactive notebooks as part of our logarithms unit. Our end of year standardized test requires students to be familiar with the change of base formula.  Last year, I used TI-84 graphing calculators with my students.  We …

## Properties of Logarithms Foldable

I created this properties of logarithms foldable for my Algebra 2 students to glue in their interactive notebooks. Properties of Logs will not be on my students’ EOI exam at the end of the year, but I still wanted to make sure they had exposure to them. I projected various logarithmic expressions on the board. …
