Decimals - Tenths and Hundredths - Presentation

The lesson on decimals is designed to help students understand and identify tenths and hundredths. It begins with a discussion prompting students to consider how many tenths make up a whole and how many hundredths are in one tenth. The lesson then delves into activities that utilise a hundred square to visually represent one whole. Students are tasked with determining the value of each individual square, each row, and the fraction that these represent. This visual aid is crucial for helping children grasp the concept of tenths and hundredths, as they work through exercises that require them to complete tables, showing how many tenths and hundredths are represented by shaded areas, rows, and columns.

Further activities challenge students to partition numbers into tenths and hundredths using a part-whole model. This includes exercises where students break down numbers such as 56, 65, or 80 hundredths into their constituent tenths and hundredths, exploring different ways to partition these values. Reasoning questions are introduced to deepen understanding, for example by evaluating statements about the equivalence of hundredths and tenths and determining the accuracy of these claims. Independent work encourages students to apply their knowledge by completing missing values on a hundred square and engaging in discussions that solidify their comprehension of the relationship between rows, columns, squares, tenths, and hundredths, as well as exploring alternative partitioning methods.
