Why do this
problem?
This jigsaw is a great way for children to reinforce their
understanding of the sequences contained within the multiplication
square and of course provides a motivating context in which to
practise their tables.
Possible approach
You could use
this
interactivity of the jigsaw as a whole class activity on an
interactive whiteboard, inviting children to explain how they would
start and then go on to complete the task altogether.
Alternatively, you could introduce the jigsaw to the whole
group and then ask them to complete it in pairs, either at
computers or by printing off and cutting out
this sheet of the grid and
pieces. The conversations they have amongst each other as they work
will be well-worth listening in on as they will reveal any
misconceptions but also inform you as to how well the children are
able to reason mathematically.
Key questions
What is the pattern of the numbers in this column/row?
Which tables will you find this number in?
What is the smallest number in the table? Where
would it go?
What is the biggest number in the table?
Can you see a pattern in the gaps you have left?
Possible extension
David Longman, a teacher at Holmemead Middle School, very kindly
suggested the following activities which complement and extend this
activity.
This sheet
is an unfinished tables square for children to complete. This
Ripped-up
Tables activity could be used as a follow-up to the
Multiplication Square Jigsaw. Not only do pupils have to put the
square together, they have to complete it first!
Possible support
At first, children may want to use a ready-made table square to
help in doing the jigsaw before trying to do again (or trying later
stages) without this aid.
