Did this today, the children quickly got teh idea that each time you add another table you get 2 more places, but we were all a bit stumped on finding a formula so that one could immediately say 'n' tables..'x' pupils.

I just grabbed the investigation as I was called in to teach at very short notice and I had to admit I had not worked it out first as I normally do :oops: I think I must have left my brain at home

There is obviously some relationship between teh number of seats you lose by putting tables together and the number you gain.

I have promised the y6 class I will et them know. So can you help me save face please! :wink:

Thank you in advance.

The formula is..... pupils = 2(number of tables) + 6

ie. p = 2n+6

Each arrangement of tables has 6 pupils + 2 pupils on the ends. therefore the number of 'pupils' will increase by 2 for each table added.

Not explained very well I know but I just seem to 'see' these. :oops:
