Sixth Grade
Today we practiced subtracting fractions. Everyone was doing really well! Here are some tips:
First, if you are subtracting a mixed number from a whole number (whole number on top without a fraction), then you have to borrow from the top whole number. Cross it off and write the number that is one less. Then make a fraction equal to one that has the same denominator as the bottom fraction. So, if the bottom fraction is 1/3, then you would make the new top fraction 3/3 so the denominators match.
When you have a mixed number minus another mixed number, you first check to make sure the denominators are the same (the ones I gave you today had all the same denominators). Then, if the top numerator is smaller than the bottom numerator, you have to borrow from the whole number. Remember, when you borrow in fractions, it's different. You get the new top numerator by adding the denominator to it. So if you had 1/3 as the top numerator and you had to borrow, then it would become 4/3 after borrowing. You get that because you are adding "1" to it infractions and 1 = 3/3, so you are adding 1/3 + 3/3 to get 4/3.
Here are a few examples:
Math - We tested today during math class. Don't forget that the dividing fractions worksheet is due tomorrow!
Geography - We reviewed for a test over Chapter 5. Study your notes and the Lewis and Clark video questions.
Pre-Algebra: We did an activity today in class using slinkys! Everyone finished and turned in their work.
Algebra I: No class today due to testing. You have the equations from words due tomorrow!
See you then...
