This math assessment workbook, "Multiply 1, 2, or 10," provides children with repeated and varied practice on the easiest multiplication facts. Students identify and extend skip-counting patterns by twos and tens, match equivalent representations of a product (repeated addition, equal groups, "tens" language, and standard multiplication notation), complete missing-factor equations, and choose correct answers from multiple-choice sets. This workbook helps students develop key math skills consistent with Common Core standards. It focuses on basic multiplication concepts and number patterns. Through exercises involving multiplying by 1, 2, and 10, students enhance their understanding of multiplication facts and will begin to feel comfortable with this new skill.
