In this lesson, students use their bodies to model the day/night cycles of the Sun and Earth. Next, they discuss the moon's role in the solar system and explore the eight phases of the moon by acting out a story. Finally, a song brings it all together to deepen the learning.

In this lesson, students interpret a poem called 'The Little Blue Engine' by adding music, movement, visual art, and drama. After performing their creation, they will discuss any mathematical and/or scientific connections that have a natural fit in this learning experience.

In this lesson, students will explore self-portraiture by looking at classical portrait paintings, such as Diego Velazquez's La Infanta Margarita or Raphael's Portrait of Baldassare Castiglione. A close look at these works reveals mathematical relationships and proper proportions that students can incorporate into their own self-portraits.

In this lesson, students will move and generate choreography to understand different states of matter.

Children need to understand why the mathematical properties work and how they are applied. In this lesson, we explore modeling and "proving" the associative property. In this lesson, we explore modeling and "proving" the associative property.

Kindergarteners need a basic understanding of measurement that leads them to know that the smaller the unit the more it takes to measure the same object using less larger units.

This short video and interactive assessment activity is designed to teach second graders about bills and coins - word problems.

Students are challenged to design a way to drop a raw egg from varying heights without letting the egg break. Creative thinking and evaluation of results are critical to the project.

This short video and interactive assessment activity is designed to teach fifth graders about challenging multi-step money problems.

These calendar activities will help students understand what a calendar is all about in terms of time measurement.

Teachers (and then students) lead the class in chanting numbers from 1 to 120.

Students calculate elapsed time using analog clocks. Included in this lesson are a detailed plan, clock template, and video of students making their clocks.

In this task using a number line, students must partition the interval between 0 and 1 into eighths.

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.
