If you’ve done all the quiz questions for this week….
That’s the American System.. this is a german one (~grade 5 I think)
From: Matthew Langham: Cows, horses and sheep
There are cows, horses and sheep on a meadow. Not counting the cows, there are 12 animals. Not counting the horses, there are 22 animals. Not counting the sheep there are 26 animals.
How many animals of each kind are there on the meadow. You may only solve this using educated guesswork and trying to arrive at a solution by adapting your guess (i.e. no computer, no algebra). How did you get to the solution?
(This is one of my daughter’s – age 10 – maths homework for today)
There are four more horses than sheep (26-22), and 12 horses and sheep put together so there is 8 horses, 4 sheep, and 18 cows.
