In this video segment from Cyberchase, the CyberSquad replaces a piece of track to get the Madre Bonita Express to the Mother's Day harvest.

A math task on Sub Claim C: Concrete Referents. Students are using a provided image to compare fractions of the same sized whole and then compare. Students explain how they know which fraction is the greatest.

This flawed reasoning task provides practice for students to understand the size of the wholes must be equal in order to compare fractions.

This flawed reasoning task provides practice for students to understand the size of the wholes must be equal in order to compare fractions.

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 is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: You and your partner will need fraction cards made from this set: Label the line-plot below with $\frac18$'s. Cut out and divide the cards evenly betwe...

This resource includes two multi-step tasks where students connect diagrams and equations in order to solve real world problems. This task includes skills learned in the common core standard 5.NF.2

Student can transfer between fractions, decimals, and percents.
Recognize equivalent forms of rational numbers.

This Nrich activity enables pupils to help to develop their concept of fractions and begin to add fractions with the same denominator and denominators that are multiples of the same number. It provides a context within which pupils can explore and reason about properties of fractions.

This Nrich activity enables pupils to help to develop their concept of fractions and begin to subtract fractions with the same denominator and denominators that are multiples of the same number. It provides a context within which pupils can explore and reason about properties of fractions.

The students will use ACC basketball statistics to practice the process of converting fractions to decimals then to percents and will learn how to create and edit a spreadsheet. They will then use this spreadsheet to analyze their data. This unit is done during the basketball season which takes approximately 15 weeks from the middle of November to the middle of March. Teachers must have Clarisworks to open the sample spreadsheet in the lesson, but may recreate it in another spreadsheet program.
