This resource will enable students to determine flawed reasoning when generating equivalent fractions using multiplication.

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 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.

This activity fits in a unit with the purpose, “Students will interpret visual information in order to make informed consumer decisions.” It is designed to get them thinking deeply about how we represent data visually, introducing the ideas of a coordinate plane (quadrant 1 only) in a very informal way – without numbers.
