  11. Todays Mission Regrouping when subtracting

  12. 1 3 5 5 1 1 2 3 1 __ __ __ __ __ __ __ __ __ 4 4 4 2 4 4 2 4 4 1 1 1 4 1 1 4 1 4 1 4 1 4 1 4 1 1 4 1 4 1 4 1 4 1 4 2 1 Regroup 2 as 1 . –1 – 1 ______ ______ = The tree has grown ft since it was planted.

  13. 3 1 1 3 __ __ __ __ Kevin and his family planted a tree when it was 1 ft tall. Now the tree is 2 ft tall. How much has the tree grown since it was planted? 4 4 4 4 The difference in the heights can be represented by 2 – 1 . First, Kevin subtracted his big numbers and got 1. However, when he went to subtract his small numbers he got realized he couldn’t take ¾ away from ¼. What should he do?

  14. Regrouping

  15. Renaming fractions I need to rename to have enough fourths to take away from Here’s how you do it! • Subtract 1 from your big • add your numerator to your denominator • Answer to step 2 is your new numerator

  16. You Try! Rename each fraction 1. 2. 3. 4. you got this!

  17. Lace up your shoes and let’s get ready to PRACTICE!!!!!!

  18. 1 1 5 6 1 5 7 1 2 1 1 5 __ __ __ __ __ __ __ __ __ __ __ __ 6 6 6 6 6 6 3 6 6 6 6 6 #1 7 – 2 7 6 Rename 7 as 6 + 1 = 6 + + . Subtract the fractions and then the whole numbers. –2 –2 ______ ______ Write the answer in simplest form. 4 = 4

  19. 2 4 7 4 7 14 4 10 7 7 4 __ __ __ __ __ __ __ __ __ __ __ 10 10 10 5 10 10 10 10 10 10 10 #2 8 – 6 10 is a multiple of 5, so 10 is a common denominator. 8 7 Rename 8 as 7 + 1 = 7 + + . –6 –6 ______ ______ Subtract the fractions and then the whole numbers. 1

  20. 2 1 3 2 3 2 __ __ __ __ __ __ 3 3 3 3 3 3 Write 6 as a mixed number with a denominator of 3. Rename 6 as 5 + . #3 6 – 3 6 5 Subtract the fractions and then the whole numbers. –3 –3 ______ ______ 2

  21. 1 4 3 12 4 4 7 16 9 9 __ __ __ __ __ __ __ __ __ __ 12 12 12 12 4 3 12 12 12 12 4 __ Rename 5 as 4 + 1 = 4 + + . 12 #4 5 – 2 The LCM of 4 and 3 is 12. 5 4 –2 –2 ______ ______ Subtract the fractions and then the whole numbers. 2

  22. 1 1 5 4 1 5 9 1 4 1 1 5 __ __ __ __ __ __ __ __ __ __ __ __ 8 8 8 8 8 8 2 4 8 8 8 8 #5 5 – 2 5 4 Rename 5 as 4 + 1 = 4 + + . Subtract the fractions and then the whole numbers. –2 –2 ______ ______ Write the answer in simplest form. 2 = 2

  23. 1 2 7 2 7 14 2 12 7 7 2 __ __ __ __ __ __ __ __ __ __ __ 12 12 12 6 12 12 12 12 12 12 12 #6 7 – 3 12 is a multiple of 6, so 12 is a common denominator. 7 6 Rename 7 as 6 + 1 = 6 + + . –3 –3 ______ ______ Subtract the fractions and then the whole numbers. 3

  24. 3 3 3 4 1 4 __ __ __ __ __ __ 4 4 4 4 4 4 #7 5 – 2 Write 5 as a mixed number with a denominator of 4. Rename 5 as 4 + . 5 4 Subtract the fractions and then the whole numbers. –2 –2 ______ ______ 2

  25. Summary In your groups, fill in the blanks If I go to subtract my fractions and there isn’t a large enough fraction to subtract from I must ____________one of my fractions. To do this I subtract 1 from my _____________ number. Next, I __________my numerator and denominator, this is my new ____________________. This whole process is called _______________________________.

  26. Homework • Practice A Regrouping Please show work on a SEPARATE SHEET OF PAPER As you are working, you can come up and get a cup of the witches’ brew
