Fractions and Paper Folding
In this fraction lesson, students manipulate paper by folding it to create different shapes and sizes, they explore the concept of fractions, and discuss their observations as a class. This is a great lesson for getting students...
Curated OER
Listen to a Shape
First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.
