Drag the pumpkins here that are wrong or false.

Drag the pumpkins here that are correct or true.

The area of a triangle with base 6cm and height 7cm is 21cm²

There are 100 centimetres in a metre.

If you subtract 15 from 3 you will be left with 12

Twice eight times seven is equal to 224

The average of

11, 12 and 13

is 12

A shape with six sides is called a Octagon

The angles in a triangle add up to 90°

If d = 2, e = 3

and f = 5 then

ef − d = 13

There are 100 grams in a kilogram.

The square root

of 16 is 4

The objective of this activity is to place each of the mathematical statements into the boxes labeled 'Trick' and 'Treat'. If the statement is true it should go into the 'Treat' box but if the statement is false it should go into the 'Trick' box.

When you think all statements have been placed in the appropriate box click the 'Check' button to see how successful you have been.

If all the statements are not in the correct boxes you will be notified of the fact but it is up to you to decide which statement(s) is/are in the wrong box(es).

If all statements are correctly placed you will win a Transum virtual trophy for this activity.

Each time this page is loaded a different combination of statements is presented for you to work with.

Have fun!

"This activity has been designed so that if you make a mistake, when you press the 'check' button you are told that at least one of the pumpkins is on the wrong side, but you are not told which one. This is to encourage you to check all of your answers and be convinced that they are all in the right place. Does that make the activity too easy, too hard or just about right?"
