"Really good site. Lots of good ideas for starters. Use it most of the time in KS3."
There are answers to this exercise but they are only available to teachers who have subscribed to Transum and are currently signed in on this computer.
A Transum subscription unlocks the answers to most of the student online exercises, quizzes and puzzles. It also provides the teacher with access to quality external links on each of the Transum topic pages so that teachers can easily find the excellent resources we have found and add to the collection themselves.
Class lists, lesson plans and assessment data can also be stored in the Class Admin application and the teacher also has access to the Transum Trophies earned by class members.
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.

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
