Fraction task
This resource will enable students to determine flawed reasoning when generating equivalent fractions using multiplication.
This resource will enable students to determine flawed reasoning in a fraction comparison with unlike numerators and denominators.
Revolutionary history recipe word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem.
Multiplying fractions on a numberline task
This resource provides students with the opportunity to base arithmetic explanations/reasoning on concrete referents such as diagrams, connecting diagrams to a written method. Students will express a fraction with a denominator 10 as an equivalent fraction with a denominator of 100 and use that information to solve a problem.
