Test Prep as a Bell Ringer
This is a pretty traditional method. Basically, you can display the problems using your document camera or project directly from your computer on a screen while students answer in their notebooks. This is usually how I used it and allowed students to use each other as a resource to complete the problems.
When the allotted amount of time was complete, we would review the problems as a class and students would complete their data sheets.
Test Prep with Stinky Feet
This is hands down my absolute favorite review game ever. I could go on, and on, and on with how much my students and I both LOVED this game. For a full description of the game, check it out here. Seriously, check it out.
One of the things that I LOVE about using this strategy is that each problem is completed cooperatively, and then you review each problem individually as you go along. So, it is a double whammy of skill reinforcement. This is also the perfect chance for students to complete their data sheets.

Use Your Interactive Notebook to Test Prep
When students have completed their work or as time allows, you go over each of the problems and complete the data sheet.

In the end, we would come back together to review the questions and for students to complete their data sheets.
Test Prep by Finding Someone Who
I always challenge my students to answer as many different questions as they can, and work with as many sets of students as possible. After the allotted time is over we come back together as a class to review the questions and complete student data sheets.

Summing Up
This is by no means an exhaustive list of how to use Test Smash which is available for math, (third, fourth, and fifth grade) science, and writing. To be honest, my first year we simply did the problems each day with very little variety. All I did was split the problems into two the first couple of days to get used to the format. The moral of this story is you do you. Is there a strategy that works well for you and your students? Use and abuse it! For my class, Stinky Feet was the absolute BEST way to get my students excited and engaged. Consequently, we played it a lot. A whole lot. Find what works for you and capitalize on it.
