2 investigations from the old SMP series.
The 'Sticks&' is involved, and has a series of extension activities, allowing for all abilities.
The second one - &';Sacks of grain' - is a challenge to pupils&' analysis skills, and uses ratio. The Maths behind it is not at all complex.
I do welcome your comments.

Two nice investigations which could be good for end of term lessons. Thanks for sharing.
