Complete the grid, then give the answer below. • Five numbers are given here- you can work out everything else. Could we still work everything out if we were gien a different set of 5 numbers? Does it matter which 5 we are given? • Can we solve a grid if only 4 numbers are given? Why/why not? • Can you make your own question up? Put the cards in the correct place on the grid [can be done with cards on the table, rather than on-screen]
