Understanding Clock Fractions and Time

This video tutorial covers a second-grade lesson on constructing a paper clock and practicing fractions while learning to tell time. It introduces a Geogebra applet for interactive learning, allowing students to manipulate clock hands and understand time concepts like 'quarter past' and 'half past'. The lesson includes activities for practicing time-telling and understanding fractions, with a focus on fraction equivalency and shaded areas. Students engage in exercises to match times to clock faces and draw clock hands, reinforcing their understanding of time and fractions.
