Playing Time: varies, user determines number of correct responses needed to win

Date: Feb 1996

Cost: $0 (donation requested by programmer...e-mail address - bobs@saintjoe.edu)

Number of Players: 1

Special Equipment/Facilities Needed: none

Subject Area: mathematics (multiplication facts)

Objectives: to drill multiplication facts and to illustrate multiplication arrays

Brief Description: After selecting the range of the multiplicand (1-9), the range of the multiplier (1-12), the maximum product (108), and the number of correct responses to win (up to 999); the game presents word problems requiring multiplication. A multiplication array is presented with corresponding graphics. For example, if the problem is "If 4 chickens each have 2 eggs, how many will there be?," the illustration will be an array of eggs two by four. The player attempts to answer the problem. If the player is unsuccessful after three attempts, the correct answer is given.

Entry Capabilities Required: basic multiplication facts, understanding of arrays

**Rating: (1-5)**

- Relevance to objectives: 5
(All problems presented are multiplication problems.)

Provides practice of relevant skills: 5 (Problems offer students practice using arrays to solve multiplication problems.)

Likely to arouse/maintain interest: 3 (Problems are similar to those found in textbooks or on paper and pencil worksheets. Students may at first enjoy the idea of using a computer. I question the game's ability to maintain interest.)

Likely to be comprehended clearly: 5 (Game is easy to operate.)

Technical quality (durable, attractive): 5 (No glitches or bugs revealed.)

Game: Winning dependent on player actions (rather than chance): 5 (Player's responses to problems are sole determinants of winning. Nearly impossible a player could guess frequently enough to win. The number of wrong answers is subtracted from the number of correct first responses to determine when the player has reached the predetermined threshold to win.)

Simulation: Validity of game model (realistic, accurate depiction): NA (Software not intended for simulation, but rather for drill of multiplication facts.)

Evidence of effectiveness (e.g. field-test results): not available

Clear directions for play: 5 (Game is easy to play.)

Effectiveness of debriefing: 3 (Score tells number of questions, number of correct responses on the first try, number of correct responses on the second try, number of correct responses on the third try, and number missed. The game does not provide insight into patterns of error. Following the player's second incorrect response, the student is prompted to count the items in the array.)

+ The teacher can set the limits of the product, multiplicand, multiplier, and winning threshold to modify the game for individual student abilities.

Weak Points: - The game offers little of the move and shoot or highly advanced graphics that most students demand.

- Following the first incorrect response, the game says "Not right. Try harder." This implies that the incorrect response is the result of insufficient effort, which may or may not be true. For students trying their hardest, this is a discouraging remark.
