All in a Jumble
My measurements have got all jumbled up!
Drag the entries in
the table up and down until all the measurements match up sensibly.
For some items there are a few numbers which would be valid. You
have to juggle them to find a combination where every measurement
is valid.
This page will be different every time you load it or refresh it -
so if you have unscrambled one set of measurements, you can try a
new set. See if you can do it with fewer uses of the 'score'
button!
Small version for getting used to
the idea:

Score - each item gets a maximum of three marks:
- correct type of unit
- within 20% of our estimate
- within 1% of our estimate
On the large version, a good strategy is to drag finished items to
the top of the list, so they won't get mixed around by your later
work. If there are a few similar numerical values in your list, you
might need to swap pairs over to get the last few marks.
Large version for a real
workout!

The following sets of cards are available if you want students to
work away from the computer. They will of course lose the facility
to check their results online.

Alternatively, you could right click over a table and select the
option to print.
