Just to say hi. I decided I will blog my thoughts and what I post and find on the website. You can add comments so I know you are out there, cut and paste bits, up to you. I can see your scrapbooks, so well done Kacey for the maths, that makes you mathematician of the day I am keeping count! The dog is loving me being home but his snoring is louder than class! I will upload learning for you in 1 week blocks, week 1 is there under homework, take a look. There are several structured lessons a week but if you manage a bit of maths a day and keep practising your number facts well done you. The whole thing is difficult. High winds here today so I lost my internet, hoping for a good day tomorrow. Email or add to the blog, this is for us and only year 5 have access. Good luck with all your home learning.

The number 0.999999….. is exactly equal to 1
Proof: Let x=0.9999…
Then 10x = 9.9999…
10x-x =(9.9999…)-(0.9999…)
9x=9
x=1
21st April 2020 Deepanshu's cat can balance die and the numbers on opposite sides of a dice always add up to seven
On a dice the numbers 1,2 and 3 all share a vertex. If these three numbers run clockwise round this vertex then the dice is called left-handed and if the three numbers run anti-clockwise round the vertex, then it is a right-handed dice. Chinese dice are normally left-handed and Western dice are normally right-handed.
The word googol was made up by a 9-year old boy
In the 1930s an American Mathematician named Edward Kasner asked his nine-year old nephew Milton Sirotta to make up a word for him to use. Milton made up the world ‘googol’ which Edward Kasner later used to describe the number . The search engine Google was later named after the ‘googol’ meaning that Milton Sirotta had unwittingly helped name one of the world’s most famous companies.
6. William Shanks calculated pi to 707 decimal places but made a mistake on the 528th digit.
