What do you think would happen if you multiplied your number by 1,000,000? Is there a pattern? Complete the pattern 28 ________________________________________ X 102 2,800 X 103 28,000 X 104 Is there a similar pattern you’ve noticed? Looking at the patterns you have identified, what conjecture can you make about multiplying numbers by powers of 10? How does the use of exponents in 102 and 103 connect to changes in the value of numbers? Multiplication Three in a Row Practice Task: In this task, students practice multiplying 2-digit by 2 or 3-digit numbers in a game format.
