Table- In general, if N is the number of days the cancer cells has been present, then the expression for the number of calls present during the nth day is 2nThe letternis called an exponent of base2.- In 22, what is the exponent? What is the base? In 23? 24? etc. What does theexponentindicate?(It indicates the number of repeated multiplication)- So, what does 23mean?(it means 2 x 2 x 2)- How is it read? ("two to the third power" or "two with the exponent three") Give some more examples.- What does the exponent tell us? What is base?

2. Fixing SkillsLet us have 3 learning stations. Do the activity in each learning station by group. Once you have finished an activity, go to the next station and do the activity indicated there. Do the activities as fast as you can.

Learning Station 1Write the number using an exponent then answer.1. 7x7x7=2. 8x8x8x8x8x8=3. 6x6x6x6=4. Two to the seventh power5. Six with the exponent nine

Learning Station 2Write the factored form then answer.1. 632. 383. 1044. 3425. 75Learning Station 3Fill in the blanks with the correct exponent form, then answer.1. 16 = 4 x 4 = ______ = ______ 16 = 2 x 2 x 2 x 2 = ______ = ______2. 81 = 9 x 9 = _____ = ______ 81 = 3 x 3 x 3 x 3 = _____ = ______3. 100 = 10 x 10 = ______ = _______ 100 = 2 x 5 x 2 x 5 = _________ = _______4. 125 = 5 x 5 x 5 = ______ = _______5. 144 = 12 x 12 = _______ = _______ 144 = 3 x 4 x 3 x 4 = ________ = _______

GeneralizationTheexponenttells the number of times the base is used as a factor. Thebaseis the number used as the factor. Theequationis the mathematical statement that two numbers or expressions are equal.

ApplicationBased on tables 1, 2, and 3, how many cancer cells have grown on the fifteenth day?

I.Learning ObjectivesCognitive:Define expressionTranslate word phrases to numerical expressionsPsychomotor:Write the correct numerical expressionsAffective:Appreciate good deeds of past presidents

II.Learning ContentSkills:1. Defining expressions2. Translating mathematical phrases to expressionsReferences:BEC PELC A. 1.1.1Materials:Interactive PowerPoint presentation, chart, stopwatch, pictures of Philippine Presidents,Value:NationalismIII. Learning ExperiencesA. Preparatory Activities1. Drill on Giving Terms or Phrases that Refer to Addition, Subtraction, Multiplication or DivisionGame: "Name-the-Baby"a) Divide the class into 2 groups.b) Teacher gives an operation, say "addition."c) Each member's of the groups simultaneously goes to the board and writes a term or phrase that refers to the given operation.Ex more than, increased by, plus, added tod) Within 2 minutes, each group has to write as many terms or phrases as they can. Afterwards, teacher checks and counts the correct answers.e) Repeat the same process with subtraction, multiplication and division.f) The group with the most number of correct answers wins.2. Motivationa) Let the pupils name the different Presidents of the Philippine from Emilio Aguinaldo to Noynoy Aquino. Show them the pictures of the different presidents and let them identify each.b) Ask: What expression describes Emilio Aguinaldo?(The President of the First Philippine Republic)What expression describes Manuel L. Quezon?(President of the Philippine Commonwealth) etc.Ask the same questions with other Presidents.c) Why should we remember our past Presidents?d) If we use expressions to describe the Presidents, we also use expressions in Mathematics, to describe relationships between numbers and the operations being used.B.
