This presentation teaches students a simplified way of calculating fractions of a whole.
It is a part of a larger unit which focuses on developing student’s understanding and proficiency in solving problems related to fractions of a whole.
Use mathematical modelling to solve practical problems, involving rational numbers and percentages, including in financial contexts; formulate the problems, choosing operations and efficient calculation strategies, and using digital tools where appropriate; interpret and communicate solutions in terms of the situation, justifying the choices made
Solve problems that require finding a familiar fraction, decimal or percentage of a quantity, including percentage discounts, choosing efficient calculation strategies and using digital tools where appropriate
Select and apply efficient mental and written strategies and appropriate digital technologies to solve problems involving all four operations with whole numbers
Find a simple fraction of a quantity where the result is a whole number, with and without digital technologies
