I estimate 140
Great, Andrés. I've "hidden" one of the photos, so as not to give too much away!
I love the way you've grouped them to help us!
I think 100 is too small and 200 is too big my estimate is 148.
Well done Andres. Seeing them in coloured groups helped to estimate more easily.
I think there are 40 blue straws,30 pink ones and 30 green ones.In total it gives you 100.
I think 200 is too big and 100 is too small, my estimate is 150.
