Fractions - Fraction Problem Solving - Presentation

The engaging fractions problem-solving activities presented here are designed to enhance students' understanding of fractions through practical examples. In the first activity, two characters, Tia and Esin, are faced with a pizza dilemma. Tia has divided each of her two pizzas into eight equal slices and consumed ten, while Esin has cut hers into ten equal slices, eating twelve. Students are tasked with determining who has eaten more pizza. To solve this, they are encouraged to use bar models, which visually represent the fractions, allowing for an easier comparison and understanding of the quantities involved.

Another activity involves a chocolate bar divided into sixteen equal pieces. Zach and Rosie are enjoying the chocolate, with Zach eating one-quarter more than Rosie, and one-eighth of the bar remaining. Students must calculate the fraction of the bar each has eaten, which involves understanding and applying addition and subtraction of fractions. Additionally, the activities explore strategies for adding mixed numbers and the efficiency of different methods. Students are also prompted to consider how bar models can aid in multiplying fractions and finding fractions of numbers. The importance of reviewing the question at the end of a word problem to ensure comprehension and accuracy is emphasized, reinforcing good problem-solving habits.
