Add & Subtract Fractions - Like & Unlike Denominators - Crack the Code

This engaging math activity is a fun way for students to get computation practice adding and subtracting mixed numbers and common fractions. They’ll enjoy the challenge and feedback is immediate through solving the puzzles (quotes from The Phantom Tollbooth) correctly.

This activity includes two different puzzles. One is addition of common fractions and the other, subtraction with mixed numbers.

Problems are set up in a table format which can be visually distracting for some students, so one of the sheets in each puzzle has a mini-alphabet table to help organize their work. The other view does not include those mini-tables, allowing students to organize their thinking in a way that works for them.

Included in this resource:

♦ A sample showing how to solve these types of problems is included for a class mini-lesson, in color/BW

♦ 25 problems (addition) 20 problems (subtraction)

♦ Adding common fractions with like or unlike denominators

♦ Subtraction with regrouping (borrowing)

♦ Finding common denominators

♦ Reducing improper fractions

♦ Reducing fractions to lowest terms

♦ Using a table to record answers

♦ All student pages are in black & white.
