Geometry and Measurement
Young geometers explore relationships between units of measure and objects. Three activities provide varied opportunities to practice. Learners calculate the volume of two cylinders made by rolling a piece of paper vertically and...
Discovery Education
Sonar & Echolocation
A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
Curated OER
Advanced Algebra with the TI-89
Pupils investigate the formulas for volumes of various solids using the Ti-89 calculator. The instructional activity focuses on the keying sequences necessary to embed the required volume formula in a program which is then used in the...
Texas Instruments
Confectionery Delight
High schoolers explore the problem of maximizing the volume of a box by making a physical model and observing how changes in the orientation of the paper changes the volume. They use the symbolic capacity of their calculators and...
Curated OER
Screaming for Ice Cream
Mathematicians investigate maximizing volume by learning to explore the problem in which they seek to maximize the volume of a cone. Students solve the problem symbolically, graphically, and through the use of integration or...
Curated OER
The Region Between Two Curves
Learners find the area of a region between two curves. They integrate functions such as sin(x) and cos(x) on a given interval and find the area bounded by the two functions. Pupils use their TI-89 to aid them in finding the bounded...

Cylindrical Soda Can
Young scholars explore an application of differentiation in this calculus activity. They investigate the ideal dimensions for a soda can and, using the symbolic capacity of the Ti-89, investigate the dimensions of the can which has the...
NOAA
Animals of the Fire Ice
When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...
Curated OER
Bird Interdisciplinary Possibilities
Students explore birds, their territory, breeding, and seasonal movement. They research and collect information on birds through writing letters to ornithologists, reading in books, comparing web sites, and observing pictures. Students...
Curated OER
Surface Areas of Prisms, Pyramids and Cylinders
Students identify and use appropriate formulas to find surface areas of solid figures, practice using formula sheet to solve textbook problems, construct solid figures of given surface area using TABS+ software program, and use Internet...
Curated OER
CO2 Blow Out!
Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.
