Students investigate unit conversion.  In this unit conversion lesson, students will build models of square and cubic centimeters using grid paper and generate formula tables for converting units of area and volume.  The tables...

Jada has a rectangle board that is measured in inches. Young learners confirm their understanding of converting inches to feet. Then they find the area in square feet. Jada thinks she has a short-cut to convert inches square to square...

Teams must determine the size of cavern needed to house the citizens of Alabraska to protect them from the asteroid impact. Using scaling properties, teams first determining the number of people that could sleep in a classroom and then...

Discover creative ways to use surface area formulas. In the assessment task, scholars apply estimation strategies to determine surface area in non-routine problems. They consider surface area of kitchen sponges, rock salt crystals, and...

Fourth graders explore unit conversions. They create visual models of measurement units, identify tables of equivalent units and make simple conversions with in a measurement system. Students produce charts that identify units of measure...

Start a trend by using blirts and gorks as your standard unit of measures. The activity asks learners to take a known measures of blirts and gorks and develop a conversion ratio. Individuals use both perimeter and area measures of...

Don't let the class tank the project. After reviewing formulas for surface area and volume, pupils design fish tanks that maximize volume. They research cost of materials online and must meet a budgetary constraint when creating their...

Boost lemonade sales by using the perfect container. For a given volume, future entrepreneurs design a container that will have the least surface area and by extension, the least cost of material. They create a two-dimensional net of...

Food companies understand how to use math to their advantage. Learners explore the math related to the packaging and serving size of yogurt. They then use unit analysis and percent values to make decisions on the product development.

Is it possible for a rectangle to have the same area and perimeter? If you disregard units, it happens! In a challenging task, groups work to determine the rectangles that meet these criterion. The hope is that learners will naturally...

For this ninth lesson plan in a larger beginning-of-the-year unit, close reading skills are used independently to find the gist of the story That Book Woman. Rereading for important details is the targeted skill to unlock a deeper...

Apply area concepts to help farmers and settle county disputes. Scholars use a given diagram and information about an insecticide spraying campaign to determine the monetary benefit to farmers. They then decide which of two counties has...

How much land does a parcel hold? How much fertilizer does it take for a field of corn? Pupils answer these questions and more as they apply ratio reasoning and unit analysis. 

It's time to discover what your classes have learned! The final lesson in the 25-part module is an assessment that covers the Pythagorean Theorem. Application of the theorem includes distance between points, the volume of...

Young scholars convert measurements from one unit to another. In this math lesson, students study the environmental consequences of oil spills. They replicate an oil spill event by modeling and scaling.

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

We all know photosynthesis happens, but why should we care? Here is a unit that covers everything young scholars need to know about photosynthesis. Hands-on activities, assessments, and lectures guide pupils though the physiology of...

The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

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...

Learners explore the concept of measurement.  In this measurement lesson, students collect data about themselves such as height, finger length, neck circumference, foot length, and other body measurements.  Learners cut squares...

Students, in groups, measure a variety of physical components to several activities. They use both standard and non-standard forms of measurement and then develop conclusions about the use of units in measurement.

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Students measure and convert between units. For this geometry lesson, students investigate through measurements of distances. They relate the properties of circle to solving problems with radius, diameter and area.

Young scholars calculate the value of a given amount of gold and silver. They convert amounts of U.S. dollars to other currencies. Students must locate the country that the foreign currency involves on a world map.
