Scientific notation was developed to assist mathematicians, scientists, and others when expressing and working with very large and very small numbers. Scientific notation follows a very specific format in which a number is expressed as the product of a number greater than or equal to one and less than ten, and a power of [latex]10[/latex].

As students work, I continually wander through the class looking for students who may need additional support. Once the timer sounds after 5 minutes, I call the class together to come to consensus on the answers. During consensus, student volunteers come to the board to explain their thinking as they work. I then ask for confirmation scientific notation problem solving the student's work or for other volunteers who found differing answers.

We work through the problems until the class is in agreement about the answers. I explain that today, we will be solving word problems using a variety of operations. CUBES is an acronym for the steps students use to solve word problems. Students must circle the numbers in the problem, underline the question, box the important words, eliminate scientific notation problem solving extra information and then solve the problem, scientific notation problem solving.

I have created a three-dimensional cube that includes the steps on each of the sides. One is in color, which I have made to show the class. Another scientific notation problem solving black-and-white and can be given to the students to construct, although I do not take the time to do that today.

Once students have been introduced to the CUBES strategy, I provide some word problems on which to apply this new strategy. I select student volunteers to help me model each step in the process. That way, students see how to apply the strategy, which we do as a whole-class activity. I ask students to record their problems in their journals.

Once both partners have written questions, they exchange journals and apply the CUBES strategy to solve. When the timer sounds after 18 minutes, I reveal today's closure activity.

Then, I ask the other student to reciprocate, so that they each have the opportunity to recall the CUBES strategy before leaving class. Empty Layer. Home Professional Learning. Professional Learning.
