Number of Players: 1

Special Equipment/Facilities Needed: a complete Macintosh

Subject Area: Mathematics grades 1-7

Objectives: To compute basic addition, subtraction, multiplication, and division problems forward and in reverse.

Brief Description: You and a dog Sparky are on a mission to find objects or to get to specific areas before the Troggles eat all of Sparky's treats, computing problems along the way. You must protect Sparky with a shield before the Troggles get him. Then you must troggulate the Troggles by computing problems correctly.

Entry Capabilities Required: Math skills that are age appropriate and quick reflexes with a mouse.

**Rating: (1-5)**
1=poor 5=excellent

- Relevance to objectives: 4
The objectives are not always met. The student must first have quick
reflexes to get to the computations. If the student is not quick
enough to get to Sparky before the Troggles do, the math calculation will
be limited to finding the sheds to do math problems before running out
of Sparky treats.

Provides practice of relevant skills: 4 When the computations are made, they are sometimes done in reverse. The student must go from the numerical answer and produce the addition, subtraction, multiplication or division problem.

Likely to arouse/maintain interest: 4 The dog is cute and the scenery changes, but it takes some time to get used to what is needed to be successful. Once students see what process is necessary, it will most likely maintain interest.

Likely to be comprehended clearly: 3 The Troggles that must be counted are difficult to see on the upper levels in order to compute a correct answer. It was not easy to see where to go when the screens change.

Technical quality (durable, attractive): 4 The scenes are somewhat interesting and they do change as you click the mouse in different directions. There are many different answers possible for each time you must keep the Troggles from getting the Sparky snacks. There must be a large data base of all the possibilities. Additionally, the wait time from when you seen the Troggles to clicking the mouse in order to protect the dog is only about 1-1 1/2 seconds. It was only slightly longer for the first graders.

Game: Winning dependent on player actions (rather than chance): 5 The possibilities of winning are good once the process is recognized. Each time the answer is correct, there is the reward of getting rid of the Troggles. Each choice determines the next step or stage of the game.

Simulation: Validity of game model (realistic, accurate depiction): 4 This model is somewhat unrealistic in the validity of the Troggles. They have a ficticious name and representation. You must also "troggulate"them.

Evidence of effectiveness (e.g. fiel d-test results): N/A I did not find any information regarding the effectiveness of this software. I believe that it would take time to have any effect on the student learning anything important.

Clear directions for play: 3 It was not clear where the student needed to go first. The introduction oval should be on the top or emphasized as the place to begin. Another option is to have the introduction within the "new game" and just have a choice to bypass. This would make it more clear.

Effectiveness of debriefing: 4 The instructions through the introduction section assisted somewhat, but they were not very clear, especially to those in the lower grades. The students would need further instruction to be sure they were attempting the correct process.

Weak Points: The amount of time doing math is only about 50% of the time spent playing the game and it was unclear how to play the game to be successful almost every time.
