There are 58 Y7 and Y8 pupils who have been selected to take place in the Junior Mathematical Challenge which will be online this year. These pupils have received instructions through Satchel One and email, including how to access practice questions. Parents have also received a text message. Further past papers for practice can be found here: https://www.ukmt.org.uk/competitions/solo/junior-mathematical-challenge/archive It will take place on Tuesday 30th June at 2pm and last for 1 hour. Pupils will receive their unique username and login via email at 9am on the day to allow them to complete the challenge.
It is incredible the commitment our pupils have shown towards Hegarty Maths as pupils’ online platform for Maths home learning. There are over 1700 schools using Hegarty Maths across the country. In the first week of home learning, Lawn Manor came 4th in the country for number of questions answered correctly per pupil and 5th in the country for total number of questions answered!
Today, over 330,000 questions have been answered since home learning began 3 months ago. We are in 46th position for number of questions answered per pupil; a huge achievement for our Mathematicians! Keep up the great work!

Pupil work
It is really important in Maths for pupils to show their workings and the notes they are making now will be useful for future revision. Thank you to pupils who have shared their home learning with us. Some amazing examples below are from Chloe Chew (Y8), Estelle Chew (Y10), Lynn Monteiro (Y10) and Melita De Souza (Y10). We also take pleasure in sharing with you some incredible work by Mangsehang Limbu (Y11), demonstrating great use of proportion in his scale model of a T-34/76 1942, a medium tank used by the Red Army during the Second World War!

Why can't you do arithmetic in the jungle? Because if you add 4 + 4 you get ate! Why do maths teachers have so much graph paper in class? They are always plotting stuff! Why did the mathematician spill all their food in the oven? The directions on the food said "Put in the oven at 180o.”

The Monty Hall Problem Suppose you're on a game show, and you're given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what is behind the doors, opens another door, say No. 3, which has a goat. She then says to you, "Do you want to pick door No. 2?" Is it to your advantage to switch your choice or stay the same?
You should switch. Keep in mind the host always opens a different door from the door chosen by the player and always reveals a goat—because she knows where the car is hidden. Contestants who switch have a 2/3 chance of winning the car, while contestants who stick to their choice have only a 1/3 chance. One way to see this is to notice that, 2/3 of the time, the initial choice of the player is a door hiding a goat. When that is the case, the host is forced to open the other goat door, and the remaining closed door hides the car. "Switching" only fails to give the car when the player picks the "right" door (the door hiding the car) to begin with. But, of course, that will only happen 1/3 of the time.
Folding a piece of paper in half If you could fold paper in half 45 times, the thickness of the paper is the same length as the distance from the Earth to the moon!
When is a coffee mug a doughnut? Topology is the branch of maths that describes shapes. We look at properties of shapes and consider how they can be recognised. So, in topology, a doughnut and a coffee mug can be classified as 'the same', this is because each of them contains a single surface and a single hole. Welcome to the strange universe of topology!
Not so random! Weirdly, random data isn't actually all that random. In a given list of numbers representing anything from stock prices to city populations to the heights of buildings to the lengths of rivers, about 30 percent of the numbers will begin with the digit 1. Less of them will begin with 2, even less with 3, and so on, until only one number in twenty will begin with a 9. The bigger the data set, and the more orders of magnitude it spans, the more strongly this pattern emerges.
Pack of cards Did you know there are more ways to arrange a deck of cards than there are atoms on Earth! Consider how many card games must have taken place across the world since the beginning of humankind. No one has, and will likely never, hold the exact same arrangement of those 52 cards you did during that game. It seems unbelievable, but there are somewhere in the range of 8x1067 ways to sort a deck of cards. That’s an 8 followed by 67 zeros. To put that in perspective, even if someone could rearrange a deck of cards every second of the universe’s total existence, the universe would end before they would get even one billionth of the way to finding a repeat. This is the nature of probabilities with such great numbers.
