Using and Applying - Number Properties

In this activity the children are given 6 statements and asked to use them to work out what unique number they all relate to.

All 6 statements will direct them to one specific number. As you might expect, this is strong on 'Using and Applying' number knowledge, as well as involving children in exploring number properties and developing their vocabulary.

To use the resource, print out the 6 page download*, cut each page into strips, keep the last strip (which shows the answer) to one side, and place the remaining 6 clues inside an envelope. I label each envelope: A, B C, D, E and F (to help with reassembling the clues later)

Each group, or pair, of children is given a different envelope and challenged to use the clues to identify the number.

For this to work, the children need to be familiar with a range of number property concepts, such as: place value, multiples, odd and even, prime numbers, square numbers, triangular numbers and Fibonacci numbers.

Here's an image of the 6-page pdf file.

The activity is based on a Year 5 lesson from Eleanor Palmer Primary School, in north London. Here's a Teachers TV video which includes a clip of children working on the activity (at about 2:57).

  Let me know how this one works for you.
