Triangle, Square, and other Polygon Puzzles. Circle Puzzles Sussex as a shepherd who had taught himself mathematics and astronomy. musicmarkup.info The Maths Year website contains puzzles and problems, and links to a number of other mathematical websites. This is a collection of puzzles for Maths lessons. Hopefully you'll find these are a it more interesting than the “Let's count up in 's” type of lesson starter that.

Students love to solve puzzles and math brain teasers! We have loads of puzzles in different difficulty levels. Our math puzzles and brain teasers are great to use a warmers during the lessons or as math activities. We have puzzles in 4 different levels: Start at the bottom left and move up, down and side ways till your path adds up to Look's easier than it is!

Hence there are no minutes left to cover the second mile. There are 7 girls on a bus. Each girl has 7 backpacks. In each backpack, there are 7 big cats. For every big cat there are 7 little cats. How many legs are on the bus, not counting the driver?

Solution There are a total of 10, legs. There are 7 girls. They have 14 legs. See the answer 10 hours 70 minutes equals 11 hours 10 minutes.

An intelligent trader travels from 1 place to another carrying 3 sacks having 30 coconuts each. No sack can hold more than 30 coconuts. On the way he passes through 30 checkpoints and on each checkpoint he has to give 1 coconut for each sack he is carrying. How many coconuts are left in the end? Solution There are 25 coconuts left.

He will give out 3 coconuts at each of the first 10 checkpoints and empty his first bag. He has two sacks left. Then he gives out 2 cocounts at each of the next 15 checkpoints, emptying his second bag. Then he has one bag of coconuts left and only 5 checkpoints to go, which means he gives out 5 coconuts from the last bag and is left with 25 coconuts. A milkman has an 8-liter container full of milk, and also two empty containers that measure 5 liters and 3 liters. He needs to deliver 4 liters of milk to a customer.

The milkman has no other spare containers and no way to mark any containers. He does not want to pour milk away. How will he measure the 4 liters of milk? Solution Fill the 5-liter container. Pour out from the 5-liter container to the 3-liter one until it's full.

The 5-liter container now has 2 liters left. Pour all the milk from the 3-liter container back to the 8-liter container.

Pour the 2 liters from the 5-liter container to the 3-liter container. It has therefore just one liter of space left!

Fill the 5-liter container. Pour out from the 5-liter container enough milk to fill the 3-liter container which already has 2 liters. You will have 4 liters left in the 5-liter container. A farmer was asked how many ducks he had. Solution There are three ducks, one in front of another.

Let's assume that in our minds because in reality it's impossible — try it yourself! How thick will such a folded paper be?

If you don't want to calculate, at least make an educated guess! Those who do not know this problem usually assume that the stack will not be thicker than up to a couple of meters. However, the thickness of a piece of paper folded in half 50 times will be surprisingly big, more than million kilometers! The distance from the Earth to the Sun is about ,, km.

The length of paper you would need for this folding would be many light years long!!!

For all levels. Favorite math puzzles for kids In February , I asked my subscribers for their favorite math puzzle. Jump to: The stars in the same row and column must have different colors. Stardoku game Turn the fish Move three sticks and make the fish to swim in the opposite direction.

You can see the solution and play an interactive version of this puzzle at Puzzles. Pigs need their pens Farmer Black raises pigs and was raising them in modular pens, He currently has 6 pigs in the following arrangement: How did he rearrange the pens so that there was only 1 pig per pen?

See the solution. Coin triangle Move only three coins and turn the triangle upside down. Click here for the answer , but not before you've thought about it! As before, most clues conform to the style employed in cryptic crosswords, where every clue is itself a puzzle as described in this Wikipedia entry , which explains how cryptic clues work. They make heavy use of wordplay such as anagramming, double meaning and other tricks that leave no doubt about the correctness of the answer, since they point to it in multiple ways.

I offer a few examples below. The number of letters in the target word or phrase is given in parentheses to make your task a little easier. Answers having multiple words are denoted by the number of letters in each word, separated by commas. The numbers are sometimes part of the answer itself: A square may contain a single decimal digit instead of a letter.

In this case, the length of the clue is prefixed by the hash symbol. At other times, letters themselves may represent a number in a way that will be obvious. Finally, the clue itself may contain a number. A four-letter-word month meets four-numbered day and boom — fireworks! Answer: JULY, and the associated number is 4. In order to help you solve the numerical clues, I have constructed an algebraic formula that relates all of them.
