Standard Form 7
A self marking exercise on scientific notation also known as standard form.
Evaluate these expressions giving your answers in standard form to two decimal places.
Try your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help.
When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file.

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

"We recently had an afternoon on accelerated learning.This linked really well and prompted a discussion about learning styles and short term memory."

"Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities.

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.
Are you looking for something specific? An exercise to supplement the topic you are studying at school at the moment perhaps. Navigate using our Maths Map to find exercises, puzzles and Maths lesson starters grouped by topic.

Level 6 - Converting to standard form. The inverse of level 3.
Level 7 - Mixed calculations.
Level 8 - Mixed calculations without a calculator.
Level 9 - Multiple choice exercise.
Finally there is a drag-and-drop standard form ordering activity.
To convert a number to standard form means to write it in the form a x 10b where a is a number greater than or equal to one and less than ten and b is an integer.
= 3.48 x 10000
= 3.48 x 10 x 10 x 10 x 10
= 3.48 x 104
= 3.48 ÷ 100
= 3.48 x 1⁄100
= 3.48 x 10-2
Finally note that any number raised to the power zero is 1 so:
= 3.48 x 1
= 3.48 x 100
