This product contains 24 Adding and Subtracting Mixed Numbers Scoot Task Cards. This is designed to help 5th, 6th and 7th graders review adding and subtracting mixed numbers (whole numbers with fractions).

I created this for my 5th graders to play in class. I arrange the cards around my classroom. I make the students fill out a piece of scrap paper showing their work for each problem. I assign the students (in groups of 2 or 3) a starting question and give them about 2 minutes to complete the question. After the 2 minutes, I tell the students to "scoot" to the next question. At the end of the game, I have the students turn in their scrap paper. Whichever group has the most questions right, wins the game. I usually provide a prize for the winner.

The students seem to like working in pairs and moving around the room. I enjoy listening to their discussions with one another regarding each question

Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
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, 𝘢/𝘣 + 𝘤/𝘥 = (𝘢𝘥 + 𝘣𝘤)/𝘣𝘥.)
