===A Note To Parents===
Developmental Learning Materials and Jerry Chaffin and Bill Maxwell of the University of Kansas have developed six programs to help your child learn the four basic math operations of addition, subtraction, multiplication, and division. Four programs emphasize-each of the math operations, and two programs develop discrimination between math operations by presenting problems in both addition and subtraction or in multiplication and division. In all six programs, an arcade game format uses colorful graphics and lively action to create an exciting, involving atmosphere for learning.
Alien Addition, one of the six Solid State Cartridges. can help your child increase speed and accuracy in the addition of numbers from 0 to 9. Alien Addition is learning combined with fun. By playing the game, your child learns and improves essential addition skills.
The arcade game format of Alien Addition is a fast-paced, outer-space version of attackers versus defender. Alien ships that have addition problems on their sides are the attackers. The defender is a laser cannon, controlled by your child, that "equalizes" the alien ships with the correct answer. Different levels of skill and problem difficulty challenge your child to improve his or her speed and accuracy. Alien Addition's colorful graphics and "outer-space" sound effects enhance the action and add to the excitement.
As the game is played, the total of "hits" (correct answers) and "misses" (incorrect answers) is displayed at the bottom of the screen and updated after each laser blast. At the end of the game a RECORD YOUR SCORE screen appears. This screen shows the totals for that game and the lowest and highest game totals for the session. But whatever the score, your child is gaining valuable practice in solving simple addition problems each time she or he plays Alien Addition.
