Decimal - Decimals as fractions - Presentation

In today's mathematics lesson, students will delve into the intriguing connection between decimals and fractions, particularly focusing on how to convert decimals into fractions with an emphasis on tenths and hundredths. The lesson begins with a discussion on what constitutes a tenth and a hundredth, setting the stage for the subsequent activities. The first activity presents a visual task where students must identify the shaded decimal and express it as a fraction. This hands-on approach aids in reinforcing the concept that decimals can be represented as parts of a whole, just like fractions.

Further into the lesson, students engage in a more challenging activity that requires them to complete a table by converting decimals to fractions in tenths or hundredths and then simplifying them where possible. This exercise not only tests their conversion skills but also their ability to simplify fractions effectively. In a real-world application of this knowledge, students are presented with a scenario involving three friends sharing a pizza and are tasked with writing the amount each child ate as a fraction, as well as determining the remaining fraction of the pizza. The lesson also incorporates reasoning exercises, where students must identify the odd one out among decimals and fractions and explain their reasoning, thereby deepening their understanding of the relationship between these two numerical representations. Independent work further solidifies their learning, challenging them to convert between decimals and fractions and to articulate their reasoning behind identifying outliers in a set of numbers.
