Footprints: Take a Step into Estimation
Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.
Curated OER
Weighing a Dinosaur
Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.
Curated OER
Math Averages
Students perform different activities to better explain that the word "Average" has 5 different meanings.
Curated OER
Dinosaur Prints
Students examine dinosaur footprints and compare them to the shape of elephant footprints and to the size of their own footprints.

Estimating the Live Mass of Dinosaurs
Students calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.

Estimation
Third graders gain an understanding of estimation as an educated guess. They explore measuring and how looking at various object size and shape can help form ones guess towards estimation. They use dinosaurs for an estimation activity.
Curated OER
Bison Calculations
Students discuss how animals are cared for when they are captured. Using calculations, they determine how much food and water it takes for one bison and compare their water intake to humans. They also compare their weight to that of a...

Science: The Age of the Redwoods
Students discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.
Curated OER
Represent Rational Numbers
Students identify expanded notation and scientific notation. In this rational numbers activity, students use a calculator to discover the powers of 10. Students practice writing numbers in expanded notation using powers of 10. Students...
