Place Value and Receipts

As it's the Half Term break, my family and I took in a spot of lunch out earlier today. We were in a well known pub chain that have an app that allows orders to be made from the table...

 

A receipt we received, contained various numbers. All the numbers need to be read in Key Stage Two. Grab a load of receipts. Can the children in Year Four/Five read all the numbers on them?

We've started a collection here.

Letter and/or Number Reversal Search

Some children struggle to write some letters and numbers the correct way around. An alternative to getting them to write out lots of the letter or number the right way can be to find the letter, in its correct orientation, on a page of correct and 'incorrect' letters.

The above example is for finding b and d. A copy of this can be found here.

Some Quite Interesting Numbers

Watching last week's QI on the BBC, they had a feature that I thought would be useful in school to ignite some interest in maths. 

What's interesting about these numbers?

The picture is the Mayan zero.

The '2 to the power of...' is the largest known prime number (at the time of writing).

If someone wrote out the numbers 1 - 10 billion in words and organised them in alphabetical order, 8,000,000,085 would be the first odd number.

142,857 is a cyclical number: multiply it by 1, 2, 3, 4, 5 or 6 and the product (each time) is an anagram of it!

Frobenius number - Chicken nuggets are sold in 6s, 9s and 20s. 43 is the largest number of nuggets that can't be bought.   

There you go. Share them as they are, or even make an investigation out of some of them. Quite interesting.
