Do you remember Farmer Joe?

 Well done, you completed the questions in the first post and yesterday you had played maths bingo in the iPad.

Do you remember Farmer Joe, who has sheep in his farm? Farmer Joe never has a straight answer, no matter what you asked him.

Today you are going to help him. Blizzard, his white cat, is on the roof of Joe's barn and neeeds to be rescued.

The barn is 5 meters high. Farmer Joe, with his arms up, can reach up to 2 meters. He has 3 questions for you.

(a) Can he reach the cat without any help?

(b) If he needs a ladder, how high the ladder has to be so he can reach the cat?

If you're stuck, try to make a drawing with the barn, Joe and the ladder. Sometimes drawing helps.

(c) Or, if instead of a ladder he decides to stack up sheep on top of each other, like this:

If each sheep is 1 meter high, how many sheep will he needs to reach the top of the barn?

Drawing might help again.
