On Thursday 4th January, Y4 had a go at an NRICH task entitled ‘Number sandwich’.
We were successful finding the correct sandwich for 3s and 4s but got stuck with 5s. However, the children displayed great perseverance trying to solve the problem, trying out different ideas based on ones that had failed.
This problem is a ‘live’ problem on NRICH so if you think you have found the solution, you can submit your answer.
