Description
This error analysis activity will make your students really think about fraction operations. Students identify incorrect statements when presented with fraction addition, subtraction, multiplication ad division problems. Students are then asked to fix each error on their answer sheet.
On each card there are 3 fraction operation problems, as well as 3 statements about the problems' answers. Students need to figure out which of the 3 statements is false (the "lie"), then correct the false statement on their answer sheet.
This activity gives students practice with the 4 fraction operations along with recognizing errors when they occur.
There are 10 cards, a student answer sheet and an answer key included.

CCSS5.NF.A.1
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, π’/π£ + π€/π₯ = (π’π₯ + π£π€)/π£π₯.)
CCSS5.NF.B.4
Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
CCSS6.NS.A.1
Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. For example, create a story context for (2/3) Γ· (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) Γ· (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (π’/π£) Γ· (π€/π₯) = π’π₯/π£π€.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi?
