Students understand that temperatures in Alaska can be negative numbers. In this temperature lesson, students recognize the temperatures above and below zero. Students compare temperatures using the greater than and less than signs....

Learners use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little meaning to...

In this composite figures worksheet, high schoolers solve 11 short answer problems. Students find the area of figures composed of various polygons. High schoolers find the area of each figure given a sketch of the figure with various...

Students plan a trip.  In this trip planning lesson, students use a map to find where they would like to visit with a pretend family of 4. They get a specific amount of money and time and need to decide where they will stay and what...

Students demonstrate how quickly disease spreads and the importance of protective measures with communicable diseases. They examine past epidemics such as the Bubonic Plague and make predictions about future epidemics.They compare and...

Students prove conjectures about geometric figures on the plane or in space using coordinate geometry. They develop fluency in operations with real numbers, vectors and matrices using mental computation or paper-and-pencil calculations...

Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.

In this factor worksheet, students practice doing factor conversions of time, length, speed, and weight. This worksheet has 12 word problems to solve.

Students read about kid's sports, why it is important and discuss the factors affecting young players. In this kid's sports lesson plan, students create a list explaining why kid's don't participate.  Students create a test to...

Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

Students in a foreign language class are introduced to the vocabulary and basic concepts involved in reading and interpreting a train schedule. They then complete a comprehension/application quiz based on a train schedule from a foreign...

Learners conduct their personal investigations into paper airplane flight. Cooperative teams are formed, with students choosing the paper airplane design that they are most interested in building.

Students calculate the distance between two points using the distance formula. In this geometry lesson, students derive the distance formula using the Pythagorean Theorem.

Second graders will be able to estimate the lengths of objects by mentally partitioning the lengths into inches. A video, worksheets, and a detailed lesson plan are included.

Animal Fun is here! In this week's adventure, Animal Measurement, children will explore measurement with the help of hermit crabs (investigating size correspondence by matching a hermit crab to its appropriate shell), beavers (visual...

Sal estimates lengths using units of inches, feet, centimeters, and meters. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video tutorial, or receive hints.
