Looking for a strategy to organize the information related to transformations? The materials ask pupils to identify a sequence of rigid transformations, identify corresponding angles and sides, and write a congruence statement. They...

Learners sometimes struggle to understand the concept of adding and subtracting integers. Help them see the why behind their answers using the interactive number line. The values change as individuals adjust the number line for each new...

After five class sessions, young scientists will be able to identify common rock types: igneous, sedimentary, and metamorphic. This plan involves hands-on activities, includes various handouts and worksheets, and requires there to be...

Practice the strategy of letter-sound correspondence when identifying the short vowel /i/ sound in written and spoken words. The teacher recites the tongue twister "Icky insect is in icky sticky ink," while listeners repeat. Letter boxes...

Turn your algebra learners into meteorologists. High schoolers are given three graphs that contain information about the weather in Santa Rosa, California during the month of February, 2012. Graph one shows temperatures, graph two...

Tenth graders explore congruent triangles.  In this geometry activity, 10th graders investigate the conditions necessary to prove two triangles congruent.  The activity combines dry erase board activities and the use of...

Students observe and create artistic representations, technological images, and scientific diagrams. They explore the five senses, the structure and function of the corresponding organs, and how the senses are connected to the human brain.

Budding mathematicians explore the concept of skip counting. They practice skip counting as they use it to determine the number of wheels that come to school at 3 different times throughout the day. They also create a data graph to show...

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons...

The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle...

Because World War II encompassed most of the globe in one way or another, many pivotal battles and events are not as visible in the history books, leaving veterans of these conflicts feeling overlooked by more famous skirmishes. High...

What do you get when you cross a circle and a line? One, two, or maybe no solutions! Teach learners to find solutions of quadratic and linear systems. Connect the visual representation of the graph to the abstract algebraic methods. 

Students explore number sense by participating in a math recognition activity. In this number identification instructional activity, students practice pronouncing names of numbers and matching the number with an amount of objects....

The form of a quadratic function paints a picture of its graph. Young mathematicians explore this connection by locating key features on a graph and then writing the corresponding equations. The interactive tutorial highlights key...

Blending basic CVC letters to make words is one of the first steps to independent reading. Provided here are several images of stairs and several letters to cut and arrange. The learner rearranges the letters to form CVC patterns, sounds...

Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...

The risk of contracting an infection in the hospital is low, but it does happen. Learn what risk factors have the highest correlation with hospital-acquired infections in the final instructional activity of a three-part series. Using the...

Build confidence in proofs by proving a known property. Pupils explore two approaches to proving base angles of isosceles triangles are congruent: transformations and SAS. They then apply their understanding of the proof to more complex...

Young mathematicians fold and flick their way to a deeper understanding of statistics with a fun, hands-on math unit. Over the course of four lessons, students use paper footballs to generate data as they learn how to create line...

What exactly does an engineer do? Learners find out through a lesson that asks them to solve a problem that affects a target population. Aspiring engineers learn the steps of the engineering design process as they apply it...

Class members perform complex operations on a plane in the 17th segment in the 32-part series. Learners first verify that multiplication by the reciprocal does the same geometrically as it does algebraically. The class then circles back...

Students examine human health by researching the internet. In this human sexuality lesson, students utilize the web to locate a website which contains information about a certain sexual aspect. Students create a group presentation on one...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Encourage effective internet research and e-mail correspondence as scholars investigate a US capital city they've never visited to find pertinent and relevant information. They begin by picking a city, then visit that city's chamber of...
