This task has student solve a two step word problem involving addition and division. Students identify flawed reasoning and provide a correct answer and explanation.

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.

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.

This resource provides students with the opportunity to solve a multi-step contextual word problem with a degree of difficulty appropriate to Grade 4, requiring application of knowledge and skills.

This resource will enable students to determine flawed reasoning in a division word problem that involves interpreting remainders.

This resource provides students with the opportunity to solve a multi-step contextual word problem with a degree of difficulty appropriate to Grade 4, requiring application of knowledge and skills.

This resource requires students to present the solution to a multi-step problem in the form of valid chains of reasoning, using symbols appropriately. Students must use the four operations with whole numbers to solve problems.
