Being a good thinker (Primary Students)

Be a mathematician (Primary Students) Mathematicians often know lots of mathematical facts, but more importantly, they think about maths in different ways. These activities are grouped to help you practise thinking like a mathematician. e.g. Pairs of numbers in working systematically

Getting started Teacher resources – always read as gives Nrich thinking around the big ideas, suggested lesson sequence, questions to ask, extension ideas. Solution – submitted by students and selected by Nrich. Gives an insight into what your students might think. https://nrich.maths.org/1885

Handy Hints Edit the problem, to make it less daunting. This doesn’t mean remove all the words (e.g. Mixed up clock) Make manipulatives – so that students can move, sort, shift the numbers/materials around Keep a list of problem links – easier to locate next time you want the problem. Make use of the curriculum map. Use the problem more than once by changing the numbers, or the context.

Mathematics in the New Zealand Curriculum Why study mathematics and statistics? By studying mathematics and statistics, students develop the ability to think creatively, critically, strategically, and logically. They learn to structure and to organise, to carry out procedures flexibly and accurately, to process and communicate information, and to enjoy intellectual challenge. By learning mathematics and statistics, students develop other important thinking skills. They learn to create models and predict outcomes, to conjecture, to justify and verify, and to seek patterns and generalisations. They learn to estimate with reasonableness, calculate with precision, and understand when results are precise and when they must be interpreted with uncertainty.  Mathematics and statistics have a broad range of practical applications in everyday life, in other learning areas, and in workplaces.
