Maths

Remember we’ve explored a variety of strategies you can use when approaching any new maths problem.

Your mathematician’s strategy toolbox includes:

  • Do I know a similar problem?j0395714.gif
  • Guess, check and improve
  • Try a simpler problem
  • Write an equation
  • Make a list or table
  • Work backwards
  • Act it out
  • Draw a picture or graph
  • Make a model
  • Look for a pattern
  • Try all possibilities
  • Seek an exception
  • Break the problem into smaller parts
  • and ……………………….

If one way doesn’t work I just start again another way.

How to read and respond to a word based maths problem:

  • make your prediction
  • list and work through the things you need to clarify such as words , phrases or concepts (include relevant facts and details)
  • identify the the BIG question
  • decide how you are going to go about solving the problem (include the strategy/ies from the Mathematician’s Toolbox you use
  • summarise the process you just went through, remember to word it so you include the initial question with your answer

 

Key Idea Interactive Activity
  • understand the size and order of small numbers (up to thousandths) and large numbers (up to millions)

  • find the lowest common multiple of numbers
Multiples in Pascal’s Triangle
  • interpret numbers and their factors by using rectangular arrays (for example, the factors of 12 can be found by making rectangles of dimensions 1 x 12, 2 x 6, and 3 x 4)

  • recognise and calculate simple powers of whole numbers (for example, 2 to the power of 4 = 16)
  • use decimals, ratios and percentages to find equivalent representations of common fractions (for example, 3/4 = 9/12 = 075 = 75% = 3 : 4 = 6
Visual Fractions

Virtual Pattern Blocks

  • explain and use mental and written algorithms (problem solving) for the addition, subtraction, multiplication and division of natural numbers (positive whole numbers)
OperationsTraining-Operations Testing
  • add, subtract, and multiply fractions and decimals (to two decimal places) and apply these operations in practical contexts, including the use of money
Adding Decimals

Adding Fractions

  • use estimates for computations and apply criteria to determine if estimates are reasonable or not
