Welcome to the use of ALGEBRA I - VERBAL PROBLEMS . There are three files on the disk. You must have all three in this SHAREWARE version. README - This is the file you are reading now. It only tells you what each file in the set does and is not needed to run the programs. But it handy to know what to do. ALG13A.PRG - This is the BOOT program for this disk. In the SHAREWARE version you must load this PRG file first, read the documentation if you want, print it out or print out an order form. Or you can just use the arrows to go to the MENU and select ALGEBRA I - V. PROBLEMS and press ENTER and the main program will run. ALG13B.PRG - This is the main program and if you have read or printed out the documentation then you know the power it has to let you configure it for your own uses. When you register your version (directions are in the BOOT program) you will receive an updated version, printed documentation, and the program will include all working functions. THANK YOU AND ENJOY!!! Educational Management Systems - P.O. Box 153 - Huntingtown, MD. 20639 The ALGEBRA I SERIES developed by Educational Management Systems under the guide of Charles O. Gauthier, Senior Programmer, is based on twenty years of teaching Algebra I by Mr. Gauthier from three different text series. The program on this disk has many features: * The user may store or retrieve the results of any work session to or from disk * The user may print worksheets with as many problems as wanted, and each would be different - there is also the option to select the help sections to be printed also to make them instuctruction worksheets * There are three levels of help available with each separate problem, and the help is geared toward helping the user to understand the specific skill for that particular problem * The entire operation of the program is within the user's control - allowing the work session to be as long short as the need be * The work and program changes use the GEM interface as much as possible - for ease of use * The user may go to the SELECT menu and make the problems more difficult, work more problems, select a higher range of digits etc. * From the OPTIONS section of the FILE, the user may change their name, the date, save a file, input a file, see the scores on screen or to the printer, or any of the other OPTION functions * Randomly generated number make each problem in each program different - and worksheets with many of the same type of problem will ALL be totally unique problems VERBAL PROBLEMS: There are 30 different types of verbal problems in 10 different areas of work that are found in all current ALGEBRA I texts used within curriculum. Each HELP section starts with a definition of what X should be, and leads the user into the relationships of that particular type of problem ( i,e.: age uses a chart, motion uses the distance formula with a chart, geometry uses the correct formula, etc.) and in the final step sets the equation up. It is assumed that the user knows the axioms and properties in LINEAR EQUATIONS before working VERBAL PROBLEMS. The types of problems covered are: NUMBER - These cover sums, differences, separate into three parts, consecutive integers and others. AGE - These cover the basic ideas of age relationships - one person being older than another and then in so many years, etc. GEOMETRY - These cover area, perimeter, right triangles, complementary angles and the Pythagorean Theorem. MOTION - These cover uniform motion in still water and people who meet when one of them leaves before the other. MIXTURE - These cover mixtures selling at different prices and percent solutions of water and alcohol. COIN - These cover 3 types of coin and value relationship. INVESTMENT - These cover interest earned on two investments and a total invested at two different rates. PERCENT - These cover the interest formula, selling price with profit and overhead figured in, and also percent of increase or decrease. WORK - These cover work by two people, work where one person starts before another and also covers the capacity of LEVER - These cover weights and distances where one distance in not known and another where the total length is known. Algebra I - Verbal Problems This version of Algebra I - Verbal Problems was written for the beginning student in algebra. There are some assumptions about the level of algebra that one needs to know before working this program. 1.) The student would have a working ability to translate from a verbal statement into the algebraic representation using LET X statements and then be able to set up and solve an equation. EXAMPLE:If a number is increased by twice itself the result is 12. LET X = a number LET 2X = twice a number X + 2X = 12 ________ _______ a number increased by twice result is 12 2.) The student would have a working knowledge of equation solving techniques and know the axioms of equation manipulation. EXAMPLE: Solve 5( X - 4) -3(3x + 6) + 42 = 8 clear parentheses 5X - 20 - 9X - 18 + 42 = 8 use the commutative property to combine 5X - 9X - 38 + 42 = 8 like terms -4X + 4 = 8 Use the additive inverse to combine -4 -4 like terms across the --------------- equal sign -4X = 4 divide by the --- --- coefficient of -4 -4 the variable X = -1 These titles will be available in a HOME VERSION and a SCHOOL SITE VERSION. The difference being that the SCHOOL SITE VERSION will be sold to a school and the school will have a license through the purchase to make duplicate copies for use within that single school, or use within a network off a hard disk drive. But more importantly there is a separate program for the teacher to enter classes, class lists and do managed instruction from any of the series titles for individual students the results of which will automatically be saved to disk. The teacher can then assess this information and make changes as appropriate. It is very important to understand that written into the programs are controls that allow the user to make changes in the parts that effect the numbers, their size, use of negative numbers etc. in order to make the program as customized as it can be for each user. Also OPTIONS are included that make it possible for the user to make use of the data generated from their use of this program, including generating worksheets of randomly generated problems, dumping to the printer problems that the user is not able to master for future study, saving to disk at any point a file with the results of the work up to that point, bringing in from disk any past file and many other OPTIONS. It is hoped that the purpose of this program: to help students understand word problems in ALGEBRA I will benefit those who spend the time working with it.
