We worked really well in Room 3 learning about factors and multiples and then using our knowledge to find the longest chain in a 100's grid.
Follow this link for the instructions - https://nrich.maths.org/5468
Use the 100's grid on this page to see if you can get a longer chain!
Well done to Hannah, Cassidy, Emma and Henry who get a chain of 39!
Another group then found a chain of 42!
If you find a longer chain let Miss Harris know!
