Find out how to make an origami paper box and explore the algebra, geometry, and other mathematics that unfolds.
Erik Tillema
A rich
understanding of multiplying binomials can be developed by working through a
series of concrete problems.
Susan Taber
When
students use manipulatives, teachers can take advantage of their surprising
solutions to engage the class in rich and productive mathematical discussions.
Jerry Burkhart
Use
building blocks to create a visual model for prime factorizations. Students can
explore many concepts of number theory, including the relationship between
greatest common factors and least common multiples.
Lauren Wagener
Consider the possibilities
when teaching slope. It is a fundamental algebraic concept that has connections
to advanced mathematics and to the world outside the classroom.
