LESSON PLAN
School : …………….
Subject : Mathematics
Main Topic : Number
Grade/Semester : VII/I
Meeting : 9 meetings
A. Standard Competence
1. Understanding the properties of arithmetic operations and use it in solving
problem.
B. Basic Competence
1.1 Doing arithmetic operations on integers and fractions.
C. Indicators
1. Doing arithmetic operations (addition, subtraction, multiplication and division)
of integers and also mixed operations.
2. Determining the properties of arithmetic operations (addition, subtraction,
multiplication and division) of integers.
3. Doing arithmetic operation (multiplication, division and exponential) on
exponential integers and also determine the properties.
4. Calculating squared and cubed then the root of square and the root of cubed in
integers.
5. Changing fractions into another form.
6. Determining equivalent fractions.
7. Comparing and ordering the fractions.
8. Explaining decimals, percent and per mill.
9. Doing arithmetic operations (addition, subtraction, multiplication, division and
exponential) of fractions.
10. Determining scientific notation.
11. Determining the rounded of decimals fractions.
12. Give example of very large and very small numbers such as mega/million (106),
For addition, the movement is forward For subtraction, the movement is backward Row direction based on integer’s kind. Positive integer, “Molat” go to the
right. Negative integer, “Molat” go to the left.
Example:
4 + 3 = 7
4 + (-3) = 1
-4 -3 -2 -1 0 1 2 3 4 5 6 7 -5 -6 -7 -8
-4 -3 -2 -1 0 1 2 3 4 5 6 7 -5 -6 -7 -8

(-4) + 3 = (-1)
(-4) + (-3) = (-7)
4 – 3 = 1
4 – (-3) = 7
(-4) – 3 = (-7)
-4 -3 -2 -1 0 1 2 3 4 5 6 7 -5 -6 -7 -8
-4 -3 -2 -1 0 1 2 3 4 5 6 7 -5 -6 -7 -8
-4 -3 -2 -1 0 1 2 3 4 5 6 7 -5 -6 -7 -8
-4 -3 -2 -1 0 1 2 3 4 5 6 7 -5 -6 -7 -8
-4 -3 -2 -1 0 1 2 3 4 5 6 7 -5 -6 -7 -8

(-4) – (-3) = (-1)
Notes:
= movement backward
= movement forward

TITLE: Exponential Integers 1. Multiplication on Exponential Integers
24 × 25 = (2 × 2 ×……….) × (2 ×……………………………..)
= 2 × 2 × 2 ……………………..
= 2 …
= 2 … + ….
So, 24 × 25 = ………
2. Division on Exponential Integers
55 =
5 × 5 × 5 … … … … … … … … . .5 × 5 × … … … .
=5 × 5 × 5 × 55 × 5 … … … … . × 5 × …
= 5 ×
= 5…..
= 5…. ⋯..
So, = ………
