Software for the teaching and learning of expansion of algebraic factors. includes factors like (x + 3)(2x - 5), (3x - 7)(x^2 + 3x - 8), etc.
Also includes formulas for perfect squares and difference of two squares. Systematic practice of the method to ensure that learners do not make careless mistakes. Diagrams are provided to help students understand the concepts better.
AlgeXpansion can generate up to 200 sums for drills per session.
A new session will generate new sums. Students can key in their own sums and let the interactive guide help them do their homework. It marks automatically and can print a detailed report after each session.
Here are some key features of "AlgeXpansion":
Tutorial:
· Teaches algebraic expansion - the expansion of algebraic expressions such as 3(x + 3), (2x - 5)(3x + 7), (x + 5)2, etc. Emphasis is on doing the expansion in a systematic way, to avoid careless mistakes. Simple exercises at the end of the sessions allow students to practice what they have learnt immediately.
Practice:
· AlgeXpansion is capable of generating hundreds of sums for drills to ensure that the student masters the skills. It includes sums involving perfect squares, such as (2x - 3)2 and difference of two squares, such as (2x + 5)(2x - 5). These sums can be solved by using formulas. More challenging sums such as (x + 5)(x2 - 5x + 6) are also included.
· The student may also key in his own sums and let the guide help him solve them.
Worked Examples:
· Almost 40 worked examples provide help for students who have difficulty in doing the sums.
· Reports:
· You can print out a report at the end of each practice session. The report shows each sum with its correct answer and the student's answer marked. It also includes the percentage score, the average time taken to do each sum and other details.
Requirements:
· 4.9MB HD space,
· 14MB RAM
· Screen resolution 800 x 600 at 16 bits or better
Limitations:
· The demo mode lets you test all the features of the software but it will automatically quit after a while.
