Decimals - Recognizing Hundredths - Presentation

In a comprehensive set of teaching slides focused on decimals, specifically the concept of hundredths, students are invited to delve into the world of fractions and their decimal equivalents. The lesson begins with a discussion on the quantity of hundredths in one whole and progresses through a series of engaging activities designed to solidify their understanding. The first activity requires students to complete number lines with fractions out of 100, providing a visual representation of hundredths. This hands-on approach helps them to grasp the idea of dividing a whole into 100 equal parts, and how these parts are represented both as fractions and decimals.

Further activities challenge students to complete sequences of hundredths, prompting them to recognize patterns and the relationship between tenths and hundredths. An intriguing element is introduced when students are asked to explain why a denominator of 10 appears in a sequence otherwise composed of hundredths. This leads to a deeper exploration of the place value system and how tenths relate to hundredths. The use of a Rekenrek, or a 100-bead string, provides a tactile learning experience, enabling students to partition fractions into tenths and hundredths and to visualize the equivalence between them. The lesson culminates in independent work where students apply their knowledge to complete number lines, sequences, and fill in the blanks in sentences, further reinforcing their understanding of hundredths as both fractions and decimals.
