Factor lines - May 18, 2022
As we continue our work on investigating properties of number this week, we have played the nrich games Factor Lines. At first we started using trial and error then realised that 21 would be the best number to position first as it has the fewest factors and multiples. We do find it frustrating to find all possibilities, especially if we forgot to work systematically.
