This task is appropriate for assessing student's understanding of differences of signed numbers. Because the task asks how many degrees the temperature drops, it is correct to say that "the temperature drops 61.5 degrees." However, some might think that the answer should be that the temperature is "changing -61.5" degrees. Having students write the answer in sentence form will allow teachers to interpret their response in a way that a purely numerical response would not.

The purpose of this task is to foster a classroom discussion that will highlight the difference between multiplicative and additive reasoning.

The purpose of this task is to assess studentsŐ understanding of multiplicative and additive reasoning.

The purpose of this task is to generate a classroom discussion that helps students synthesize what they have learned about multiplication in previous grades.

This short video and interactive assessment activity is designed to teach third graders about comparing quarts and pints by formula.

This task can be used to either build or assess initial understandings related to rational approximations of irrational numbers.

In this activity students read a list of laws regulating Africans and African Americans and a servant's indenture contract from colonial New York. Then students find evidence in the primary sources to support a series of statements about the differences between slaves and servants in the period. This activity includes scaffolds and vocabulary support for students with literacy challenges.

Students must calculate the volume of a cone in this real world task.

This task provides the opportunity for students to reason about graphs, slopes, and rates without having a scale on the axes or an equation to represent the graphs. Students who prefer to work with specific numbers can write in scales on the axes to help them get started.

The purpose of this task is to help develop students' understanding of addition of fractions; it is intended as an instructional task.

The purpose of the task is for students to compare signed numbers in a real-world context.

The focus of this task is on understanding that fractions, in an explicit context, are fractions of a specific whole. In this problem there are three different wholes: the medium pizza, the large pizza, and the two pizzas taken together.

Many students will not know that when comparing two quantities, the percent decrease between the larger and smaller value is not equal to the percent increase between the smaller and larger value. Students would benefit from exploring this phenomenon with a problem that uses smaller values before working on this one.

The purpose of this task is for students to compare a number and its product with other numbers that are greater than and less than one.

This short video and interactive assessment activity is designed to teach second graders about comparing and writing decimal inequalities in word problems.

In this task students are required to compare numbers that are identified by word names and not just digits. The order of the numbers described in words are intentionally placed in a different order than their base-ten counterparts so that students need to think carefully about the value of the numbers.

The Compassion Project has both digital and off-line components covering: defining empathy and compassion, practicing mindfulness and growth mindset, identifying emotions, and performing acts of kindness

When most people think of the Civil Rights Movement in America, they think of Martin Luther King, Jr. Delivering his "I Have a Dream" speech on the steps of the Lincoln Memorial in 1963. But "the Movement" achieved its greatest results due to the competing strategies and agendas of diverse individuals.
