IXL: Math Practice - Scientific Notation

Details

Activity Description

 

This activity gives students the needed practice to reinforce classroom instruction on Scientific Notation. Students are asked to convert from standard form to scientific notation. Students who answer incorrectly are given an explanation of the correct solution and an opportunity to try again.

This site requires a paid membership; however, you are permitted free access to 20 questions per day. IXL provides differential instruction and tracks student progress with the paid subscription. The questions will automatically increase in difficulty as the student improves.

The cost is not exorbitant, but at the present time, it is $299 per year and up for your class.

Preparation

1. Check to be sure that the site is not blocked by your school.
2. Be sure to review the topic of scientific notation the day before.
3. Try some of the exercises to check the difficulty level. Students will need to be able to convert from standard form to scientific notation and vice-versa. Review if necessary.
4. Create a short formative quiz to check for understanding.

How-To

1. Introduce the lesson on scientific notation and discuss the High School Equivalency test and the importance of being able to convert between standard form and scientific notation. Try to use real life applications.
2. Teach the concept of standard form and scientific notation and how to convert to each.
3. Select "W.1 Convert between standard and scientific notation" listed under Scientific Notation to generate equations.
4. If you have access to a computer lab, give students time to practice their skills. Walk around the room, to view their scores. If students have Internet access at home, encourage students to practice their skills at home and record their scores.
5. The next day, discuss any difficulties students had with the problems and re-teach as necessary.
6. Check for understanding by giving a short formative quiz.
7. Re-teach concepts as needed.

Teacher Tips

• The material is already divided by grade level and in order of difficulty. When teaching a lesson, for instance, proportions, just follow all the links in the order it shows under the words "Scientific Notations".
• It keeps track of problems attempted and time elapsed.
