Students become familiar with the similarities and differences between electronic and printed text by comparing the textual aids included in a textbook with those of an educational website.

This short video and interactive assessment activity is designed to teach second graders about using a place value chart to compare and write decimal inequalities.

This short video and interactive assessment activity is designed to teach second graders an overview of comparing decimals.

This short video and interactive assessment activity is designed to give fourth graders an overview of comparing decimals.

This short video and interactive assessment activity is designed to teach fourth graders about comparing capacities in compound units using words (english units).

This short video and interactive assessment activity is designed to teach second graders about comparing capacity with pictures (english units).

This short video and interactive assessment activity is designed to teach third graders an overview of conversion among units of measure.

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

This short video and interactive assessment activity is designed to teach second graders about comparing cups and pints by pictures.

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

This short video and interactive assessment activity is designed to teach second graders about comparing cups and quarts by pictures.

Students create different versions of a known song and listen to contrasting recordings for musical differences and similarities.

Which side will win as students investigate both sides of the battle of using print versus online text for research as they learn about the lives of Civil War soldiers?

This task gives students an opportunity to work with exponential functions in a real world context involving continuously compounded interest. They will study how the base of the exponential function impacts its growth rate and use logarithms to solve exponential equations.

Students discuss and compare differing versions of Little Red Riding Hood and other tales about wolves in cumulative read-aloud sessions and text set explorations.

The purpose of this task is for students to compare fractions using common numerators and common denominators and to recognize equivalent fractions.

This task is meant to address a common error that students make, namely, that they represent fractions with different wholes when they need to compare them. This task is meant to generate classroom discussion related to comparing fractions. Particularly important is that students understand that when you compare fractions, you implicitly always have the same whole.

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.
