Grade 8 Math: 1.5 Expanded Form and Scientific Notation
In this lesson, students will learn to (1) evaluate, compare and order simple powers, (2) investigate properties of powers and (3) write numbers in expanded form and scientific form.
The lesson starts by defining the terms scientific notation and expanded form, and gives an example of each. There are four examples in this lesson, each followed by practice questions. The first example helps students discover patterns in powers of 2 and powers of 10. The second and third are concrete examples of how to use scientific notation. The final example shows how expanded form works.
Students might benefit from this video series, which starts with finding the value of a power of ten, and moves into scientific notation.
