This lesson plan outlines a mathematics lesson on scientific notation for 6th grade students. The objectives are for students to learn the definition of scientific notation, how to convert between scientific and standard form, and how to add numbers in scientific notation. The lesson will begin with an opening prayer and questions to motivate students. It will then explain the key concepts and processes for scientific notation through examples on the board. Students will have the opportunity to practice these concepts through board work and recitation.

2. C. ABSTRACTION
SCIENTIFIC NOTATION is a special way of writing too big or too small
numbers that are difficult to express.
A number written in Scientific Notation
has three parts
Standard Form to Scientific Notation:
(1) Move the decimal point so that the number is greater than one but less ten .
(2) Remove any insignificant zeros.
(3) Count number of decimal places the decimal has "moved" from the original
number. This will be the exponent of the 10.
(4) If the original number was a small number, the exponent is negative; if the
original number was a big number, the exponent is positive.
Scientific Notation to Standard Form:
(1) Move the decimal point the same number of spaces as the exponent.
(2) Positive exponents = big numbers, so move the decimal point to the RIGHT.

but lessthanten
A power of ten
A multiplication
sign

3. (3) Negative Exponents = small numbers so move the decimal point to LEFT
(4) Fill in any empty spaces with zeros and rewrite the number.
Adding Numbers in Scientific Notation:
(1) The numbers need to be expressed in the same form.
(2) This means to rewrite with the same exponents.
(3) Then factor the GCF (powers of 10).
(4) Line up the decimals to add.
(5) Write in scientific notation.
