When learning about midpoint and distance in the coordinate plane, children learn how to apply the formula for finding the midpoint, as well as use the distance formula and the Pythagorean theorem to find the distance between two points. As a teacher, you may find that, sometimes, children struggle with these math concepts, and you […]

Proving Theorems in Geometry
When students start learning about proving theorems, they already have some knowledge of what a theorem is. For example, they’ve come across the Pythagorean Theorem in earlier grades. Much of their work in geometry will consist of proving theorems. And even for the best of math students, this can be a bit of a challenge! […]
Teaching Logic in Geometry
When building arguments, mathematically fluent students can understand and use definitions, assumptions, and facts. They can justify their statements and conclusion by relying on logic. This is why it’s important to teach logic in math. This of course includes teaching logic in geometry as well. But if you’re a math teacher, you are probably aware […]
