This short video and interactive assessment activity is designed to give fourth graders an overview of telling time to 1-minute intervals.

This short video and interactive assessment activity is designed to give fifth graders an overview of time (5 minutes).

This short video and interactive assessment activity is designed to teach fifth graders about visually finding weight in compound units.

This short video and interactive assessment activity is designed to give fourth graders an overview of metric units of weight.

This short video and interactive assessment activity is designed to give fourth graders an overview of comparison of weights (metric units).

This short video and interactive assessment activity is designed to give fifth graders an overview of comparison of weights (metric units).

This short video and interactive assessment activity is designed to teach fifth graders about identifying basic 2d shapes in composite figures.

This short video and interactive assessment activity is designed to teach fifth graders about identifying equivalent fractions (missing number).

In this task students use algebraic methods to determine whether each of the functions is odd, even, or neither.

This task emphasizes the expectation that students know linear functions grow by constant differences over equal intervals and exponential functions grow by constant factors over equal intervals.

Gait analysis is the study of human motion that can be utilized as biometric information or identification, for medical diagnostics or for comparative biomechanics. In this activity, students observe walking human subjects and then discuss parameters that could be used to characterize walking gaits. They use accelerometers to collect and graph acceleration vs. time data that can help in gait analysis—all part of practicing the engineering data analysis process. Students complete this activity before learning the material presented in the associated lesson.

The goal of this task is to get students to focus on the shape of the graph of the equation y=ex and how this changes depending on the sign of the exponent and on whether the exponential is in the numerator or denominator. It is also intended to develop familiarity, in the case of f and k, with the functions which are used in logistic growth models, further examined in ``Logistic Growth Model, Explicit Case'' and ``Logistic Growth Model, Abstract Verson.''

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

The goal of this task is to work on finding multiples of some whole numbers.

This identification guide provides technical descriptions and photos for Ohio’s 21 invasive and noxious weed species. These descriptions include information on habitat, life cycle, key plant characteristics, and a summary of problematic features. Photos included in this guide present the weed species at different stages of maturity for optimal identification aid. This book also provides information on Ohio’s noxious seed law, extension guides to weed control, and a quick guide to weed regulations in Ohio law.

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 aspects of the task and its potential use.

This short video and interactive assessment activity is designed to teach second graders about identifying parallel and perpendicular lines.

This short video and interactive assessment activity is designed to teach fourth graders about calculating quotients (numbers up to 100,000).

This short video and interactive assessment activity is designed to teach fourth graders about identifyinging prime or composite numbers.
