June Challenge - Years 1 & 2

Barnaby Bear has just come home from his travels.  He needs to remember his door code in order to open his front door.  He needs to arrange 6 coloured pegs correctly into a rectangular grid for the door to unlock.  He wrote himself three clues to help him remember where each peg goes.  Can you help him work out where to put each peg?

Clues:

Red is below blue.

Yellow is between blue and green.

Pink is to the left of orange and red.

left	top			right
	bottom

Tip:  First, find the colour of each of the six pegs.  Use coloured circles of paper to move around to try to satisfy the clues.

Solutions are to be completed by Friday 30^th June.  Please post them into the Maths Challenge Box in the picture book library.

June Challenge - Years 3 & 4

Moneybags

The giant has 20 gold coins.

He sorts them into three moneybags.

The second bag has fewer than ten coins inside.

The third bag has one more gold coin than the first bag.

The second bag has three more coins than the third bag.

How many coins are in each of the moneybags?

Hint: Use coins or pasta to represent the gold coins.  Try to sort the objects into bags or bowls so that the rules are satisfied.  It might take a few tries.

June Challenge - Years 5 & 6

Take your seat

Jasper had waited all year for the talk by Professor Filament from the University of Bright Sparks.  He had already bought his ticket for £5 and walked into the auditorium to find his seat.  Already the place was buzzing with excitement.  He read the instructions to find his seat.

“PLEASE READ THIS CAREFULLY.  Your seat is in a row that is eleventh from the front and sixth from the back.  There are fifteen seats on your left and nine to your right.  WARNING!  If you sit in the wrong seat you will be asked to leave the room and someone else will take your place.”

After some thought and a bit of searching Jasper exclaimed, “Ah there I am, right between those two ladies.”

Problem:

1.       How many seats are there in the auditorium?

2.       If the auditorium was full, how much money did Professor Filament make from his talk?

3.       If the auditorium was only a quarter full, how many people turned up?

Hint:  Drawing a diagram might help you get started.

May Challenge - Years 3 & 4

When I went into a classroom earlier this week a child rushed up to tell me she was 8 that day!

Well, Happy Birthday to everyone who has a birthday today!

If you are 8 then this could be for you, but if it is another number then you just change the 8 to whatever your age is today.

There is not a lot to say to introduce this challenge. It's really just to find a great variety of ways of asking questions which make 8.  Sums like 6+2, 22−14, etc.

But you need to get examples that use all the different mathematical ideas that you know about.

1) So you could show some multiplications and some divisions.

2) If you know about fractions then you can add or subtract numbers involving fractions. You could also ask questions like "What is half of 16?''; "What is four-fifths of 10?'' and so on.

3) If you've come across decimals then do a few of those also, perhaps using all the four rules (addition, subtraction, multiplication and division).

And so on.

Use whatever mathematics you know to find as many different ways of getting the answer 8.

April Challenge - Years 1 & 2

There are three baskets, a brown one, a red one and a pink one. Together they are holding a total of ten eggs.

The brown basket has one more egg in it than the red basket.

The red basket has three eggs less than the pink basket.

How many eggs are in each basket?

Getting Started:

Cut out ten eggs from paper and get three containers to represent the baskets.  Have a go at trying some different combinations.

After a while ask this: 

Why don't you choose a number of eggs for the pink basket? How many would be in the red basket, then? And how many in the brown basket?
