Fractions

Thursday in class we learned about fractions. A fraction is a order pair of integers that look like this ( 1/2), sometimes the numbers are writen one number above another. The top number represents the numerator and the secound number represents the denominator.The most common use of fractions involve (The part to whole concept). For example:

All the circles are a whole but when you color half of the circle, you now get 2 halfs of the 1 whole circle which is written 1/2 as pictured above. The same operation would be done for the 1/3 circle an the 3/6 circle. Some teachers use fraction strips that represent the same concept as the circles.We learned that when adding fractions you have to find the same denominator, so you would look for the LCM of the two numbers.Than you would multiply the two fractions numerator and the denominator by the factors that make the LCM.Than you would add the two numerators and the two denominator together for your answer.

MULTIPLYING,DIVIDING,ADDING, AND SUBTRACTION OF INTEGERS

The lesson today was about integers and Time and Temp, Debits and credits , i was confused on how she showed us on how to do the problems.The man walking forward and backward, i did not get it. Today we had two presentations on fractions they both were good, since i have not done a fraction for a while. This web site help me understand what she was talking about in class .

INTEGERS RAP

This is a video about integers which we learned about today in class. We learned about negative and positive intergers that can be confusing. Both of the presentations were done very well.
