GRADE 7 - PROBABILITY

Learning Outcomes 
Students will be able to solve probability involving simple events

The probability of an event is its CHANCE of happening. This will be a number from 0 to 1. The Theoretical probability of an event , E, is the number of times the event can occur divided by the total number of possible outcomes ( as long as each outcome is equally likely to occur ). From the results of an experiment or sample, we can calculate the experimental probability. This is used as an estimate of the theoritical probability. When carrying out an experiment to find the experimental probability of an event occuring, we are actually finding the relative frequency of that event. Relative frequency of a score = frequency of score : total frequency 

Here some experimental probability that students do during the lesson : 
1. Probability tossing a coin 
2. Probability tossing a dice 
Student trace and color the net of die
Student cut the net of die
Student construct the net to be 3D die
Student throwing die and record data on their book
After they do experiment, students make a written report, here the sample of written report that they have done 

Final project for this unit is students create a creative games in group of 2 . They make a planning first and start to construct the game board and all the equipment needed, trials the games and the last one is they make a written report of all the process.
