Tug of WarThe young farm animals have been playing

tug of war. With 3 piglets on one side and 2 kids (young goats) on the other side, the game ended in a tie. Similarly, with 3 calves on one side and 4 kids on the other side, the game ended in a tie. Which side, if either, will win if one side has 5 piglets and the other side has 2 calves?

Page 66: BRAIN GYM - stpaulsprimaryschoolfarington.co.uk · Insert the correct mathematical signs between each number in order to resolve the equation. 84 ÷ 7 3 = 36 + - x ÷ + ÷ - x - +

Tug of WarAnswer

The 5 piglets will win. If there were only 4 piglets on one side and 2 calves on the other side, it would be a tie. Here's one way to solve the puzzle. The puzzle tells you the following:2 kids = 3 piglets 3 calves = 4 kids Those facts mean the following are also true:4 kids equal 6 piglets 3 calves equal 6 piglets Therefore, 1 calf = 2 piglets. It follows that 2 calves = 4 piglets. If 2 calves and 4 piglets would tie, then 5 piglets would beat 2 calves.

Insects and SpidersAs you know, one way to tell an insect

from a spider is to count its legs. All insects have six legs, and all spiders have eight legs. So if some insects and spiders went to a dance, and there were 48 dancing legs, how many insects and how many spiders were at the dance? Four insects (24 legs) and three spiders

(24 legs). No other combination will work.

Moving Day

The Masters family is moving to a new house. They have a dog, a cat, and a pet mouse, but the animals don't get along in the car, so they can take only one at a time. Then there are other problems. They can't leave the dog alone with the cat, because the dog chases the cat if no one is watching. And they can't leave the cat and the mouse together, because...well, you know what would happen if they did. How can the Masters family get all three of their pets to their new house?
