Example video^^^
Laws of exponents song!!
--We are going to create a song for how to solve one-step and two-step equations. Think of a song to do a parody on; write the lyrics to make the solving equations clear. Think of what and who you want in the video--dancers, teachers, principals, mascot..etc.--

Unit 2 is all about the number system!
We started with changing fractions into decimals and vise versa.
For fractions to decimals we have to use our long division skills to divide the numerator by the denominator.
For decimals to fractions. Read the decimal in proper mathematical language. For example .56 ==> fifty-six hundredths ==>56/100
Remember you are not done till you simplify them! 56/100 divided by 2/2 = 28/50 still not simplest form = 28/50 divided by 2/2 = 16/25. Now that 16 and 25 have nothing in common we know that 16/25 is in simplest form and we are DONE!!
