Recognizing that children�s understanding of number is the main focus of math instruction in the primary grades, these lessons build on arithmetic concepts and skills to develop children�s algebraic thinking. Manipulative materials, problem-solving investigations, games, and real-world and imaginary contexts support arithmetic learning while introducing ideas basic to algebra, including patterns, equivalence, and graphing.
