Dinosaurs - Lesson Focus
LESSON 1: Long Ago
BIG IDEAS: Dinosaurs existed many years ago; we have found their
bones. Zero is the number that tells how many dinosaurs exist today.
LESSON 2: Extinction
BIG IDEAS: Life can cease to exist because the conditions on earth
that support it change and no longer meet a life form's needs. Dinosaurs'
needs were very large.
LESSON 3: Fossils
BIG IDEAS: Paleontologists dig for fossils to help us learn about
the kinds of animals that lived long ago. Good guesses can be made from
careful observations.
LESSON 4: Types of Dinosaurs
BIG IDEAS: There were many different kinds of dinosaurs: some
walked on land, others flew in the air and others lived both on land and in
water. We can use geometric shapes to draw their pictures.
LESSON 5: Meat and Plant Eaters
BIG IDEAS: Dinosaurs existed by eating large quantities of plants
like ferns or by eating other animals. We can classify dinosaurs in many
different ways.
LESSON 6: The Dinosaur's Life Cycle
BIG IDEAS: Dinosaurs hatched from eggs laid by the female
dinosaur; the baby dinosaurs grew to be adults. Mathematics also tells us
about patterns in the lives of dinosaurs.
LESSON 7: Nature and Change
BIG IDEAS: The story of the existence and extinction of dinosaurs
tells us that change is a part of nature. Change can be observed by making
comparisons and by using mathematics.
