Did you know that Pluto is smaller than the United States of America? It is difficult to conceptualize the size of planets and the distance between them, and the lesson addresses those exact issues. After a discussion, pupils create...

Young scientists learn how to select a scale factor for a large scale model. Then they figure the scale for each of the planets and the distance between them. Finally, they construct a giant scale model of the solar system and answer...

Visual models support young mathematicians with exploring equivalent fractions. Starting with a quick warm-up problem, children go on to work through a series of guiding practice problems before working with a partner identifying and...

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson. Using fraction circle manipulatives, children explore basic unit fractions as they develop the fundamental...

How do you create a residual plot? Work as a class and in small groups through the activity in order to learn how to build a residual plot. The activity builds upon previous learning on calculating residuals and serves as a...

Add another strategy to the toolboxes of young mathematicians with this elementary math lesson on using number lines to add and subtract fractions.

Create a graph for anything in the world. Pupils continue to work with graphs that model situations. The learners analyze different graphs to answer questions about the scenario along with finding equations of graphs. Scholars use...

Viruses can spread like wildfire, and mathematics can model the speed of infection. Given a function, scholars analyze it to describe the spread of a disease within a stadium. Learners find the initial number infected and the maximum...

Explore linear functions! In this Algebra I instructional activity, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

 Introduce learners to what factoring represents and it's relationship to a square with a resource about factoring and the method of area models. The questions are scaffolded to begin with introductory questions and eventually have...

Use a unit approach in developing a fraction division strategy. The teacher leads a discussion on division containing units, resulting in a connection between the units and like denominators. Pupils develop a rule in dividing fractions...

Which function models the data best? Pupils work through several activities to model data with a variety of functions. Individuals begin by reviewing the shapes of the functions and finding functions that will fit plotted data points. By...

Teaching linear function relationships using contextual information is beneficial to pupils' understanding. The lesson uses problem solving to build linear functions given different information for each problem. This is the second...

Explore our world from within as you lead young scientists on a thrilling adventure. Pupils examine the location of plate boundaries to determine earthquake and volcano distribution around the globe and explore the cause of hot spots in...

Here is an online quiz, complete with answer links. High schoolers respond to nine short answer questions about Joan of Arc, her battles, and even the voices in her head. The best part, they can check their own answers.

Readers are asked to use the provided graphic organizer to list the main idea and supporting ideas in a passage from L. Frank Baum's The Wonderful Wizard of Oz.

Readers analyze an excerpt from Kate DiCamillo's novel Because of Winn-Dixie. They read silently, and then hear it read aloud. Definitions for underlined vocabulary words are in the margin, and other potentially difficult words...

Using a paragraph from Jack London's Call of the Wild, readers demonstrate their ability to identify the main idea and supporting ideas in a passage.

Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup...

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

What an impressive task it is to make dental impressions! Pupils learn how dentists use proportional reasoning, unit conversions, and systems of equations to estimate the materials needed to make stone models of dental impressions....

Scholars crave practical application. Let them use the different models of a quadratic function to plan the size and shape of a school playground. They convert between the different forms and maximize area.

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...
