This activity investigates how you might make squares and pentominoes from Polydron.
Using the 8 dominoes make a square where each of the columns and rows adds up to 8
Place the numbers 1, 2, 3,..., 9 one on each square of a 3 by 3 grid so that all the rows and columns add up to a prime number. How many different solutions can you find?
We had lots of solutions to this problem but not many of you told us how you got your solutions. Luis and Freddie, who go to Newton Prep, sent in well-explained solutions. Here is what Luis wrote:
Many children from Stradbroke Primary School sent an image of their solution. Here is George's:
