Start the lesson by giving your students a basic definition of what probability is. Probability is the chance that a particular outcome will occur.
Relate the definition you gave to something that your students can relate to. For example, you might ask them what they think the probability is of a coin landing on heads.
Use a simple spinner to help demonstrate the concept of probability. For the basic education level, the spinner should have four colors.
Show the students how to determine the probability that the spinner will land on one of the four colors. There are four different colors, and the spinner can only land on one at a time. Therefore, the probability that the spinner will land on each color is one in four.
