Mathematics Grade 6

This lesson will strengthen students' understanding of scientific notation.
Students were introduced to the concept of exponents in fifth grade.
Scientific notation is writing a number as the product of a number (greater than or equal to 1 and less than 10) and a power of ten. We use scientific notation because numbers can be hard to work with when they have so many zeros. Scientists use scientific notation as a simpler way to write these numbers.
1. Demonstrate a positive learning attitude toward mathematics.
2. Become mathematical problem solvers.
3. Reason mathematically.
Invitation to Learn
Mercury is about 35 million miles from the sun.
Have students estimate how long they think it would take to write 35 million numerically (35,000,000).
Write down estimation.
Have each student (or one student) write out 35,000,000. Time to see how long it takes.
Have students find the person with the equivalent number. They may attempt to identify the number by asking yes or no questions only. The round continues until all students have found their partner. You may want to play a second round using the remaining cards.
