Chef's Tip
When mixing your ingredients, remember to find a common denominator first! If you're subtracting and your top fraction is smaller than the bottom, you might need to decompose a whole number to "borrow" more fractions.
1
The Soup Pot: Addition
Problem A
\( 2 \frac{1}{3} + 4 \frac{2}{5} = \)
Problem B
\( 5 \frac{3}{4} + 1 \frac{1}{2} = \)
Problem C
\( 3 \frac{2}{7} + 2 \frac{1}{3} = \)
Problem D
\( 6 \frac{5}{6} + 3 \frac{3}{4} = \)
2
The Chopping Block: Subtraction
Problem E
\( 8 \frac{4}{5} - 3 \frac{1}{2} = \)
Problem F
\( 5 \frac{1}{4} - 2 \frac{3}{4} = \)
Problem G
\( 7 \frac{1}{6} - 4 \frac{5}{8} = \)
Problem H
\( 10 \frac{2}{9} - 6 \frac{2}{3} = \)
3
Kitchen Catastrophes
Chef Marco is baking a giant cake. He mixed \( 4 \frac{2}{3} \) cups of flour into the bowl, but then realized he needed a total of \( 9 \frac{1}{4} \) cups. How much more flour does Chef Marco need to add?

A. \( 2 \frac{1}{3} + 4 \frac{2}{5} = \mathbf{6 \frac{11}{15}} \)
B. \( 5 \frac{3}{4} + 1 \frac{1}{2} = 6 \frac{5}{4} = \mathbf{7 \frac{1}{4}} \)
C. \( 3 \frac{2}{7} + 2 \frac{1}{3} = \mathbf{5 \frac{13}{21}} \)
D. \( 6 \frac{5}{6} + 3 \frac{3}{4} = 9 \frac{19}{12} = \mathbf{10 \frac{7}{12}} \)
Subtraction Answers
E. \( 8 \frac{4}{5} - 3 \frac{1}{2} = \mathbf{5 \frac{3}{10}} \)
F. \( 5 \frac{1}{4} - 2 \frac{3}{4} = 4 \frac{5}{4} - 2 \frac{3}{4} = \mathbf{2 \frac{1}{2}} \)
G. \( 7 \frac{1}{6} - 4 \frac{5}{8} = 7 \frac{4}{24} - 4 \frac{15}{24} = \mathbf{2 \frac{13}{24}} \)
H. \( 10 \frac{2}{9} - 6 \frac{2}{3} = 10 \frac{2}{9} - 6 \frac{6}{9} = \mathbf{3 \frac{5}{9}} \)
Word Problem Solutions
9. Flour Problem:
\[ 9 \frac{1}{4} - 4 \frac{2}{3} \rightarrow 9 \frac{3}{12} - 4 \frac{8}{12} \rightarrow 8 \frac{15}{12} - 4 \frac{8}{12} = \mathbf{4 \frac{7}{12} \text{ cups}} \]
10. Bagel Problem:
\[ 12 \frac{1}{2} - 7 \frac{4}{5} \rightarrow 12 \frac{5}{10} - 7 \frac{8}{10} \rightarrow 11 \frac{15}{10} - 7 \frac{8}{10} = \mathbf{4 \frac{7}{10} \text{ dozen}} \]

1. Mix it up! (Addition)
\[ 3 \frac{5}{6} + 2 \frac{1}{4} = 3 \frac{10}{12} + 2 \frac{3}{12} = 5 \frac{13}{12} = \mathbf{6 \frac{1}{12}} \]
2. Slice it off! (Subtraction)
\[ 6 \frac{1}{3} - 4 \frac{1}{2} = 6 \frac{2}{6} - 4 \frac{3}{6} = 5 \frac{8}{6} - 4 \frac{3}{6} = \mathbf{1 \frac{5}{6}} \]
Chef's Reflection Criteria:
Students should identify at least one of these key steps:
Finding a common denominator before calculating.
Checking if regrouping/borrowing is necessary for subtraction.
Simplifying the final fraction or converting improper fractions.
