This lesson can be used as a pre-lesson for the Powers of 10 lesson plan.
Students will be able to multiply by powers of ten to identify number patterns.
Students will be able to discuss patterns with the powers of ten using a graphic organizer and peer conversations.
Display the completed Growing by Powers of Ten Chart (i.e., the answer sheet) and ask students to discuss their observations with partners, sharing what they notice about the chart. Model an example for them and write the sentence starter on the board for them to use in their conversations (e.g., "I notice the numbers increasingly get larger in each additional row.").
Draw a three-column chart on chart paper or use the T-Chart with Three Columns worksheet to keep track of students' thoughts. Label the headings of the T-chart "Notice," "Know," and "Wonder."
Share some of the things that students noticed about the chart from the notes you took on the T-chart. Ask students if they would like to add to an explanation or share anything new.
Explain to students this chart shows the power of ten in multiplication, which means the number gets bigger and bigger exponentially as the product is multiplied by ten. Tell them they will begin to notice patterns of ten and discuss exponents and its relationship to the powers of ten.
