This short video and interactive assessment activity is designed to teach third graders about determining whether lines are perpendicular.
This short video and interactive assessment activity is designed to teach third graders an overview of quadrilaterals.
This short video and interactive assessment activity is designed to teach third graders about counting the number of basic 2d shapes in a composite figure.
This short video and interactive assessment activity is designed to teach second graders about counting the number of different 2d shapes in a composite figure.
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 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).
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.
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.''
The goal of this task is to work on finding multiples of some whole numbers.
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.
This task requires students to determine whether a number is rational or irrational. The task assumes that students are able to express a given repeating decimal as a fraction.
This short video and interactive assessment activity is designed to teach second graders an overview of quarter-circles and semi-circles.
This short video and interactive assessment activity is designed to teach third graders an overview of quarter-circles and semi-circles.
This short video and interactive assessment activity is designed to give fourth graders an overview of quarter-circles and semi-circles.
This short video and interactive assessment activity is designed to teach third graders an overview of reflective symmetry.
