More number pyramids
When number pyramids have a sequence on the bottom layer, some interesting patterns emerge...
Square coordinates
A tilted square is a square with no horizontal sides. Can you devise a general instruction for the construction of a square when you are given just one of its sides?
Rhombus it
Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a rhombus.
Square it
Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a square.
Factors and multiples game
A game in which players take it in turns to choose a number. Can you block your opponent?
Triangles in circles
Can you find triangles on a 9-point circle? Can you work out their angles?
Semi-regular tessellations

Play this game and see if you can figure out the computer's chosen number.
Diamond collector
Collect as many diamonds as you can by drawing three straight lines.
Last biscuit
Can you find a strategy that ensures you get to take the last biscuit in this game?
Tilted squares
It's easy to work out the areas of most squares that we meet, but what if they were tilted?
Cyclic quadrilaterals
Draw some quadrilaterals on a 9-point circle and work out the angles. Is there a theorem?
What numbers can we make now?
Imagine we have four bags containing numbers from a sequence. What numbers can we make now?
Number pyramids
Try entering different sets of numbers in the number pyramids. How does the total at the top change?
Parallelogram it
Players take it in turns to choose a dot on the grid. The winner is the first to have four dots that can be joined to form a parallelogram.
