Grades K-2 Mathematically Speaking Many situations in elementary school mathematics provide teachers an opportunity to have their students create, extend and describe patterns. This is crucial to the development of algebraic concepts in the young learner. Algebra can be defined as the study of patterns.
Patterns weave mathematical topics together.
Through the study of patterns, children learn to see relations, and make connections, generalizations, and predictions about the world around them. In this lesson we can express the relationship between the number os squares and the number of triangles.
