activities can be used either by individual pupils, small groups or with
the whole class using a projector or an interactive whiteboard.
than just a game, not really a game at all. Use Rob8 to investigate
functions and their graphs.
The aim is to find out what operations each of Rob8's brains performs.
There are four types of brain (same brains) which do the same operation
every time you use this activity. Each of these brains carries one
of the four operations: addition, subtraction, multiplication or
Two types of brain (random brains) are slightly random: ie the operation
they carry out might change. These brains also carry out one of
the four operations.
The special brains do the same each time: it could be quite tricky
to work out what they do.
Pupils should describe the brains according to the shape pattern
on them; thus using their knowledge of polygons.
Lots of 'what happens if...' questions can be asked if used with
the whole class.
Elephant Wallpaper to investigate number sequences and nth
terms. A small piece of 'wallpaper' is shown, the aim is to decide
what colour the elephant is at given coordinates. Click on the elephant
of your choice then the 'final answer' button. A much larger piece
of wallpaper is revealed showing the elephant in question. Points
are scored for correct answers. Try to score as many as possible
in 5 minutes. The levels become progressively more difficult. Experts
can start at a higher level.
Lots of discussion and strategies could be provoked if used with
the whole class.
fishy simultaneous equations. Three fish are weighed in pairs. The
aim is to work out the weight of each fish. Try to score as many
as possible in 5 minutes.
are the best strategies to use to work out the weight of each fish?
the 'Solve It' calculator to solve simultaneous equations. Add or
subtract the expressions to eliminate either a or b.
You have 5 minutes to solve as many equations as you can.
Click on a calculator button to enter an expression. The calculator
will work out the value of the expression and display the equation.
Either add or subract other expressions to try to eliminate a
