Z-kai’s math contents and curriculum have all of these components.

Z-kai offers educational services in Japan from its inception in 1931, particularly focused on developing challenging material for advanced and gifted preK-12 students. Through experiences educating more than 200,000 Japanese students each year, Z-kai has learned that it is better for students to solve a limited number of well-thought-out problems rather than numerous less-challenging ones. In this way, students’ mathematical knowledge, thinking skills, and processing are maximized and made more flexible.

Zoom-Up Series Value Proposition

Z-kai’s Zoom-Up Workbook is tailored to develop students’ mathematical thinking, problem solving, and explanation skills that are necessary for their future success in STEM. Zoom-Up Workbooks contain many problems that challenge students, because the problem solving requires them to apply mathematical concepts and develop skills that are uncommon to the mathematics curricula and instruction of most schools and classrooms.

This series was developed to reflect or surpass grade-specific Common Core State Standards in Mathematics (CCSS-M, 2010). The application of mathematical reasoning, problem solving, and explaining mathematics provides multiple opportunities for students to apply the CCSS-M Standards for Mathematical Content and Practice.

This Zoom-Up Workbook contains 45 challenging problem sets that have been carefully selected to optimize students’ understanding and perseverance. Given a limited number of total problems, the focus is on depth of understanding rather than breadth of completion. Solving challenging tasks will help students develop confidence and motivation.
