Some fun maths challenges from St. Patrick's School in Bray

Coughing over trays of liquid nitrogen with and without N95 mask, face shield, and surgical mask.

For younger kids, giving them physical objects to play around with can really help them solve this puzzle...

[Stpatsmathschallenge @Stpatsmathscha1]

A farmer needs to get a bag of seeds, a hen and a fox across a river. He can only take one thing in the boat with him each time. If he leaves the fox and the hen alone together the fox will eat the hen. If he leaves the hen and the seeds alone together the hen will eat the seeds.

[Stpatsmathschallenge @Stpatsmathscha1]

How does he transport all three things safely to the other side of the river?

@hilaryconnolly Well done Ella! 👏👏👏

[Stpatsmathschallenge @Stpatsmathscha1]

Can you draw this shape without lifting your pencil or going over the same line twice?

[Stpatsmathschallenge @Stpatsmathscha1]

How many squares can you see? Don't forget to use the strategies you used for the rectangle problem we did before...Good luck!

[Stpatsmathschallenge @Stpatsmathscha1]

For the older kids - if you had two dice how many different combinations of numbers could you get if you threw them both? What about if it was a 10 sided die or 12 sided?

[Stpatsmathschallenge @Stpatsmathscha1]

For the younger kids - can you find some different ways to put the coloured squares into the bigger box? You could draw the shape on a piece of paper and see how many different solutions you can come up with.

[Stpatsmathschallenge @Stpatsmathscha1]

There were some excellent attempts to this problem.
Now for the solution.....
Remove the matchstick from the top and bottom of the zero and use them to make a 1 in front of the 5. That will give you 15118.
Then just look at it upside down and you get 81151.
Well done everyone!

[Stpatsmathschallenge @Stpatsmathscha1]

This is one for the older kids. For the younger ones try to find some shapes in the world around you..

[Stpatsmathschallenge @Stpatsmathscha1]

For the younger classes, give them an items to hold in their hands and then ask them to find some items that are heavier or lighter.

[Stpatsmathschallenge @Stpatsmathscha1]

For the middle classes, could you estimate the weight of some objects and then weigh them using the weighing scales and see how close you get. Don't forget you will need some items with a known weight to compare them to, otherwise it would just be a guess and not an estimate...

[Stpatsmathschallenge @Stpatsmathscha1]

Some weights problems to start the week. This one is for the older classes. Can you figure out how much the three animals weight altogether?

[Stpatsmathschallenge @Stpatsmathscha1]

@orlsmcc Fantastic work Clodagh! Well done. 👏

[Stpatsmathschallenge @Stpatsmathscha1]

So today's challenge is to see if you can make patterns. For the infants, see how many different patterns you can make using the cutlery in your kitchen. You could post a photo or a video.....

[Stpatsmathschallenge @Stpatsmathscha1]

@hilaryconnolly A little hint...... remove sticks from the zero.....

[Stpatsmathschallenge @Stpatsmathscha1]

@fbutler07 Fantastic work Sophie. Well done!!! 👍

[Stpatsmathschallenge @Stpatsmathscha1]

For the older classes: can you make 6 squares by moving only 2 matchsticks?
I will post the answer to last week's matchstick problem later today so last chance to try it if you haven't already....

[Stpatsmathschallenge @Stpatsmathscha1]

@hilaryconnolly Look at that upside down Ella and see what you get. Excellent work. It can actually go a little higher but love how you are thinking...

[Stpatsmathschallenge @Stpatsmathscha1]

Today's challenge for the younger classes: take out 8 matchsticks or spoons or cut out 8 strips of paper. See what different shapes you can make. Try it a few times and see if you can come up with different solutions. We would love to see some photos.

[Stpatsmathschallenge @Stpatsmathscha1]

For the older kids, can you make patterns using numbers? Maybe you could even use fractions or decimals? We would love to see some photos or videos....
