Decimals - Hundredths as Decimals - Presentation

In a series of engaging activities focused on understanding hundredths as decimals, students are introduced to the concept of representing fractions as decimals. The lesson begins with a recap, asking students to remember how many hundredths make up one whole and to complete sentences reinforcing this concept. They are then encouraged to discuss and visualise the division of a whole into equal parts. As the lesson progresses, students are tasked with completing tables that help them connect visual representations, words, fractions, and their corresponding decimal forms. For instance, the fraction 56/100 is equivalent to the decimal 0.56, and similarly, 17 hundredths is written as 0.17. These exercises not only strengthen students' understanding of decimals but also reinforce their ability to convert fractions to decimal notation.

The lesson continues with more in-depth activities where students write numbers as both fractions and decimals, exploring different representations of the same value. For example, four hundredths is shown as 0.04 in decimal form and as 4/100 in fraction form. Students also engage in reasoning tasks, such as evaluating statements to determine their accuracy—for instance, correcting the misconception that 16 hundredths is the same as 1,600. Additionally, they are presented with scenarios where they must decide between two interpretations of a decimal, understanding that 0.60 and 0.6 represent the same value. Independent work further consolidates learning, with students completing tables and creating their own examples, while discussions encourage them to compare and contrast fractions and decimals, deepening their comprehension of the mathematical concepts involved.
