Fractions - Fractions of an amount (1) - Presentation

The lesson on fractions is designed to help students understand how to find a fraction of an amount, with a focus on unit fractions. A unit fraction is a fraction where the numerator is one, and students are encouraged to provide three examples to demonstrate their understanding. The lesson includes a series of activities where students apply their knowledge to practical examples, such as dividing Malachi's goldfish or Leanna's marbles into equal groups and determining what fraction of the total each group represents. The activities are scaffolded to ensure students can grasp the concept of finding a fraction of a set of objects and apply it to various scenarios.

Further reinforcing the concept, the lesson involves using bar models and place value counters to visualize and solve problems related to fractions of amounts. For instance, students might use the bar model to find one-fifth of 66 or one-third of 18. Independent work tasks challenge students to fill in missing values and draw their own bar models to find solutions to fraction problems. The lesson also prompts critical thinking through reasoning questions, where students must consider which mathematical operations to use and how many equal groups are needed to find a fraction of an amount. The bar model is highlighted as a useful tool for helping students understand the partitioning of amounts into fractions.
