G. Learning Activities
 Introduction
Fase 1 : Clarify goals and establish set
- Teacher generally presents the learning objective that is determine the mean,
median and mode of single data.
- Apperception : Teacher leads the students to recall the lesson that had been learnt
in the previous meeting that is about frequency distribution table, cumulative
frequency, interval class and middle value.
- Motivation : Teacher motivates the students by relating the material that being
discussed with real life situation, for examples; if we have a collection of data, we
can determine the central tendency by calculating the mean, median, and mode of
those data.
 Main Activities
Fase 2 : Demonstrate knowledge or skill
- Teacher explain about mean in single data.
Fase 3 : Provide guided practice
- Teacher gives a frequency distribution table and asks the students to determine the
mean.
- Teacher guide the students in determining the mean.
Fase 2 : Demonstrate knowledge or skill
- Teacher explain about median in single data.
Fase 3 : Provide guided practice
- Teacher gives a frequency distribution table and asks the students to determine the
median.

3. - Teacher guide the students in determining the median.
Fase 2 : Demonstrate knowledge or skill
- Teacher explain about mode in single data.
Fase 3 : Provide guided practice
- Teacher gives a frequency distribution table and asks the students to determine the
mode.
- Teacher guide the students in determining the mode.
Fase 4 : Check for understanding and provide feedback
- Teachers check students' understanding by giving a quiz.
 Closing
Fase 5 : Provide extended practice and transfer
- Teachers encourage students to review the material that was learned today.
- Teachers give homework to students.
