Investigate how this pattern of squares continues. You could measure lengths, areas and angles.
A follow-up activity to Tiles in the Garden.
Explore one of these five pictures.
What is the smallest number of tiles needed to tile this patio? Can you investigate patios of different sizes?
Place four pebbles on the sand in the form of a square. Keep adding as few pebbles as necessary to double the area. How many extra pebbles are added each time?
How many ways can you find of tiling the square patio, using square tiles of different sizes?
What do these two triangles have in common? How are they related?
Investigate all the different squares you can make on this 5 by 5 grid by making your starting side go from the bottom left hand point. Can you find out the areas of all these squares?
I cut this square into two different shapes. What can you say about the relationship between them?
A thoughtful shepherd used bales of straw to protect the area around his lambs. Explore how you can arrange the bales.
Polygonal numbers are those that are arranged in shapes as they enlarge. Explore the polygonal numbers drawn here.
If I use 12 green tiles to represent my lawn, how many different ways could I arrange them? How many border tiles would I need each time?
Arrange your fences to make the largest rectangular space you can. Try with four fences, then five, then six etc.
Cut differently-sized square corners from a square piece of paper to make boxes without lids. Do they all have the same volume?
This challenge extends the Plants investigation so now four or more children are involved.
An investigation that gives you the opportunity to make and justify predictions.
What happens to the area of a square if you double the length of the sides? Try the same thing with rectangles, diamonds and other shapes. How do the four smaller ones fit into the larger one?
Place the 16 different combinations of cup/saucer in this 4 by 4 arrangement so that no row or column contains more than one cup or saucer of the same colour.
These pictures were made by starting with a square, finding the half-way point on each side and joining those points up. You could investigate your own starting shape.
What is the largest number of circles we can fit into the frame without them overlapping? How do you know? What will happen if you try the other shapes?
While we were sorting some papers we found 3 strange sheets which seemed to come from small books but there were page numbers at the foot of each page. Did the pages come from the same book?
The letters of the word ABACUS have been arranged in the shape of a triangle. How many different ways can you find to read the word ABACUS from this triangular pattern?
Compare the numbers of particular tiles in one or all of these three designs, inspired by the floor tiles of a church in Cambridge.
A challenging activity focusing on finding all possible ways of stacking rods.
It starts quite simple but great opportunities for number discoveries and patterns!
An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.
Use the interactivity to find all the different right-angled triangles you can make by just moving one corner of the starting triangle.
How many tiles do we need to tile these patios?
Investigate the number of faces you can see when you arrange three cubes in different ways.
Can you continue this pattern of triangles and begin to predict how many sticks are used for each new "layer"?
This tricky challenge asks you to find ways of going across rectangles, going through exactly ten squares.

This challenging activity involves finding different ways to distribute fifteen items among four sets, when the sets must include three, four, five and six items.
How many shapes can you build from three red and two green cubes? Can you use what you've found out to predict the number for four red and two green?
In this investigation, you must try to make houses using cubes. If the base must not spill over 4 squares and you have 7 cubes which stand for 7 rooms, what different designs can you come up with?
Can you find out how the 6-triangle shape is transformed in these tessellations? Will the tessellations go on for ever? Why or why not?
48 is called an abundant number because it is less than the sum of its factors (without itself). Can you find some more abundant numbers?
This activity asks you to collect information about the birds you see in the garden. Are there patterns in the data or do the birds seem to visit randomly?
In my local town there are three supermarkets which each has a special deal on some products. If you bought all your shopping in one shop, where would be the cheapest?
How many different ways can you find of fitting five hexagons together? How will you know you have found all the ways?
Can you find ways of joining cubes together so that 28 faces are visible?
