Three children are going to buy some plants for their birthdays.
They will plant them within circular paths. How could they do
this? 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. This challenge extends
the Plants investigation so now four or more children are
involved. 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? Suppose we allow ourselves to use three
numbers less than 10 and multiply them together. How many
different products can you find? How do you know you've got them
all? Cut differently-sized square corners from a square piece of
paper to make boxes without lids. Do they all have the same
volume? In a Magic Square all the rows, columns and diagonals
add to the 'Magic Constant'. How would you change the magic
constant of this square? Inves
