Book excerpt: We believe kids get better at math with practice, resulting in confidence and positive attitude towards math that is required to excel in school. This workbook provides kids with additional math practice that reinforces and complements what is taught at school. There are no pictures or word problems, and focus on mastery of basic addition and subtraction. This workbook combines traditional addition and subtraction math problems, with number bond problems. Many elementary schools teach math using Number Bonds, and we want kids to have practice on both traditional math questions and number bonds to build fluency and speed in basic arithmetic.
