Decimals - Hundredths on a Place value Grid - Presentation

In a series of engaging educational slides, students are introduced to the concept of hundredths and their representation on a place value grid, which is a key component of understanding decimals. The lesson aims to deepen the learners' comprehension of how hundredths relate to tenths and to whole numbers. Students are prompted to think critically about the quantity of hundredths in a tenth and the number of tenths in one whole, setting a solid foundation for the activities to follow. These discussions and activities are designed to help students visualise and articulate the structure of decimal numbers, enhancing their fluency and reasoning skills in the subject of decimals.

The practical exercises involve writing down the decimal that corresponds to the digits placed in the ones, tenths, and hundredths columns on a place value grid. For instance, if a grid shows 1 in the ones place, 3 in the tenths, and 0 in the hundredths, the decimal represented is 1.3. Further activities encourage students to construct decimals on the grid themselves, using sentence stems to describe the numbers, such as "There are 0 ones, 3 tenths, and 4 hundredths," which translates to the decimal 0.34. Additionally, students explore different ways to partition decimals using a place value grid and a part-whole model, fostering a deeper understanding of how decimals can be broken down into their constituent parts.
