The 1st Grade Math Comparison, Subtraction and Multiplication Basics workbook introduces 1st graders to three basic arithmetic operations. Use of a three-sector numbers introduction button for teaching three basic operations provides common contextual background which makes comparison, subtraction and multiplication easier for understanding and practice. From cognitive standpoint a common contextual background turns all three parts of a three-sector number button into one unit which contributes to better understanding of functions of numbers in basic arithmetic operations. The workbook provides practice for basic arithmetic operations with numbers 1 to 12.
