EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.
Find a great variety of ways of asking questions which make 8.
If you had any number of ordinary dice, what are the possible ways
of making their totals 6? What would the product of the dice be
This problem challenged you to check
your understanding of the building blocks of maths: "plus",
"minus", "divide", and "multiply". You noticed that the
of numbers and symbols is important; in
different positions, the "number sentence" can say different
things. This is the same as when you speak or write; the order of
the words matters. However, with some of the number sentences,
there are two different orders, which still mean the same thing.
Again, this is like speaking or writing; even if the order is
different, it can sometimes mean the same thing.
For the first four questions, you were
asked to put the correct symbol into the box. Several students
submitted correct solutions. These include: Jonathan, Jordan, and
Callum from Aycliffe Drive Primary School, Lauren from Princess
Elizabeth, Anna, Isabella, George, Sophie, and Rhiannon from St.
Swithun's, Nathan from Wilson's, Rebecca from Bourne Westfield
primary school, Ayush from Garden Gate Elementary School, Brandon,
Narissa, Jordan, Justin, and Cameron from Village Elementary, and
Charlotte from Manor Preparatory School.
Narissa and Jordan wrote out the answer:
Rhiannon, from St Swithun's Primary
School approached this problem by trial and improvement: she placed
a different symbol in the box, and looked to see if the calculation
made sense. In this way, she worked out the correct
The next part
of the problem asked you to fill in the symbols, like in the first
section. However, all of the number sentences but two have two
different solutions. Ayush, from Garden Gate Elementary School
submitted the correct solution:
As Aimee, from Culford School points out:
Rebecca, from Bourne Westfield Primary
A few people noticed a reason why there can be
two different solutions for the number sentence. As Jonathan,
Jordan and Callum, from Aycliffe Drive Primary School point out,
"plus" and "minus" are inverse operations (processes), as are
"multiply" and "divide". This means that you can do a sum, for
example a multiplication, and then undo it, by doing the reverse,
or "inverse": divide.
Thank you to everyone who submitted answers!
Well done to you all!
