 # WODB – the challenge of oranges and bananas

Real life applications of Math – the main purpose of the tasks. Homework, classwork or exams must be fun and also improving mathematics education. Cool math game combinated with Earth problems and social responses thinking is another goal of the tasks.

In mathematics, the greatest common divisor (gcd) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For example, the gcd of 8 and 12 is 4. The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Denominator (LCD). For two integers a and b, denoted LCM(a,b), the LCM is the smallest integer that is evenly divisible by both a and b. For example, LCM(2,3) = 6 and LCM(6,10) = 30.

WODB (which one does not belong). This is a type of test where one image does not belong to the other three by some feature. Sometimes there are many signs and another picture does not fit. Such tests are very good at determining the learner’s logic and thinking direction. WODB is the basis for debate and debate when everyone is trying to prove their truth.
