Rational Numbers and Fractions

The lesson introduces classifying rational numbers, exploring division as fractions using clay blocks. It explains the relationship between division and fractions, and how to write rational numbers in the form a/b. Venn diagrams are used to classify rational numbers, integers, and whole numbers. Practice problems reinforce the concepts, and financial literacy examples demonstrate real-world applications. The lesson concludes with a summary of key points.
