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?

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 3 - Converting from standard form. Mixed including zero as the index.
Level 4 - Converting to standard form. The inverse of level 1.
Level 5 - Converting to standard form. The inverse of level 2.
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
