Mathematical Reasoning Grades 2-4 Supplement - Lower Elementary Mathematics to Non-Routine Problems (Grades 2-4)

This 325-page book develops investigative, analytical, and explanatory skills as well as a variety of quantitative and spatial relationships that are an essential part of the foundation of mathematics.

Students who successfully complete this book will see gains in vocabulary development, observational skills, and the ability to process mathematical concepts on a much higher level. The activities are arranged in six sections which address six major strands in the elementary mathematics curriculum.

Number and Numeration
Discussion and analysis of counting, comparison, and numeration.

Geometry
Description, classification of shapes, composition of figures, and elementary spatial sense.

Operations
Builds on number and numeration using conceptual development of addition, multiplication, and subtraction. Applies these operations in problem solving.

Measurement
Integrates number and geometry concepts using length and area.

Relations
Uses order, number patterns, and functions to explore number relations.

Tables and Graphs
Involves organizing, displaying, and using data in a variety of formats.
