Sunburst Math Arena Lab Pack (10) for Mac,Windows
Author: admin // Category: maths competitions
Grade Levels: 4 7 Let the practice begin! Improve your math performance through training! Enter Math Arena and participate in over 20 different activities that align with the NCTM Standards and can be adjusted to meet the needs of students of all levels of ability. As students interact with the various activities, they practice key skills and develop a better understanding of mathematical concepts, all in a fun and engaging environment. Students are challenged to improve math skills, and develop an ability to use math in practical situations in 20 action packed activities that focus on: visual thinking numeration and operations estimation and prediction money sense data representation geometry concepts Students can select two levels of difficulty in a timed or untimed learning environment. Students compete individually, in small groups, or on teams. In this positive, outcome oriented program, your students will think on their mathematical feet with unique visual opportunities to: engage in probability problems predict number sequences perform visual transformations find coordinates on a grid add and subtract percentages create mirror reflections learn about the degrees of a circle construct Venn diagrams estimate and keep tallies in their head perfect operations skills practice checking for mistakes Each activity provides clear, explicit instructions with visual demonstrations, rousing music, and appropriate sound prompts. Students understand the purpose and the expectation of each activity, and practice in the Train mode. In the Compete section, students work individually, in small groups, or on teams in timed or untimed trials to win or lose points in three round challenges that are followed by a summary and reinforcement event called The TriMathlon. A teacher’s management section lets you create specific sets of challenges for students, devise formats for friendly classroom competition, and maintain ongoing assessment records.

Scoring System
Questions 1 to 10 are worth 3 points, 11 to 20 are worth 4 points and 21 to 25 are worth 5 points. Questions 26 to 30 are worth 6, 7, 8, 9 and 10 points, respectively.
No penalties apply for wrong attempts. Maximum score equals 135 points.
The first 25 questions are multiple choice with 5 choices. The last 5 question have an integer answer between 0 and 999.
Here are sample questions used recently as 26 to 30 Questions which are typical of these with 0 to 999 integer solutions.

Language : Why do I find much more difficult to read novels rather than essays?
Author: admin // Category: difficult mathematics problemsI'm not an English-native speaking.
For Instance : I can read without problem the " essentials of Mathematica 7" ( a book about the mathematics software by Wolfram), but for me it's quite understandable " A Mercy" by Tony Morrison, of whom I will have to buy the translation as well.
Because novels not only have a richer vocabulary, but also use many figures of speech and allusions without laying out the meaning directly and dryly as non-fiction does. A novel, like poetry, often suggests things rather than telling them. When reading a novel, you are a co-participant with the author in negotiating meaning.

Evaluating challenging integrals via differentiation: Leibniz rule
Author: admin // Category: difficult mathematics problems
I discuss and solve a challenging integral. The method involves differentiation and then the solution of the resultant differential equation. The so-called Leibniz rule for differentiating integrals is applied during the process. Such an example is seen in 2nd-year university mathematics.

Australia maths competition intermediate question 24. 2008
Author: admin // Category: maths competitionsPQR is an equalateral triangle. The point U is the midpoint of PR. Points T and S divide QP and QR in the ratio 1:2. The point of intersection of PS, RT and QU is X. If the area of triangle QSX is 1 square unit, what is the area, in square units, of triangle PQR?
The area of a triangle is
A = (1/2)bh
The small triangle QSX has a base 1/3 that of large triangle PQR.
The small triangle QSX has height 1/4 that of large triangle PQR.
So the ratio of areas of the large to small triangle is:
(3/1)(4/1) = 12
The area of the large triangle is 12.
