Exploring Mathematical Statements

Mathematical practices extend beyond conceptual knowledge. Practices used by good problem solvers involve explaining, justifying, arguing, representing and generalising.

In Maths this week we investigated a Mathematical Statement that some of our students have been curious about: If you add the same amount to both numbers in a two digit subtraction problem, how might it affect the answer? 

We found out that if you add the same number to both numbers you get the same difference.

Our Success Criteria was to:

  • Explain our reasoning
  • Say whether we agree/ disagree
  • Listen to others and take on new ideas
  • Negotiate a shared understanding of ideas
  • Record our ideas in written form
