Comparing Fractions
1/2 + 1/3 > 1
False, I know 1/2 + 1/2 =1 and 1/3 is less than 1/2
On your white boards, add 1/3 + 2/9. To do this show an equivalent fraction
Check number line on white. 1/3 = 3/9 and then add the 2/9 and it should be just past one half showing the answer of 5/9.
4/9 + 2/4 > 1
False, I know that 4/9 < 1/2 and that 2/4 = 1/2. So 1/2 +4/9 is less than 1
On a number line show 5/8 + 1/2
9/8
5/6 + 1/12 < 1
True! 5/6 +1/6 =1 and I know that 1/12 < 1/6
Show 1/4 + 2/3 on a number line
See whiteboard (11/12)
2/3 + 1/4 > 1
False, I know that 1/3 > 1/4 because a third divides the whole into 3 pieces and a 1/4 into 4 pieces. Therefore, 2/3 + 1/4 < 1
Show 5/6 + 4/5
See whiteboard
9/12 + 1/4 < 1
Show 1/2 plus 1/3
See white board
