The Happy Numbers team consists of experienced teachers, mathematicians, methodologists, designers, developers, writers, illustrators, and customer service professionals.
While cubes and other manipulatives support learning by representing numbers, the number line actually develops learning by giving students another look at number relationships...
After mind-growing lessons that focus on conceptual understanding, can students succeed on such abstract tests that only measure procedural fluency? Will the tests cause trauma or anxiety in our youngest students (as it often does in teachers!)? At Slackwood Elementary School in New Jersey, math specialist George Regan set out to answer these questions with some research of his own.
A Guessing Jar is one of my favorite activities for promoting number sense and an awareness of how large a number is. I love that it can be filled with anything small or large and right away we have a number activity that is unique every time.
