Individualized support through practical math games in four different levels! Mastering calculations up to 1000, including written and semi-written methods, is essential knowledge for children in primary and special education. This volume playfully practices and trains these fundamental skills, with a focus on individualized support. For each topic, there are four practice games at various levels and with different game formats – including solutions! The games contain between 12 and 20 tasks for addition and subtraction (written and mental calculations) as well as multiplication and division (semi-written and mental calculations). The last group of games focuses on solving word problems related to important quantities. The exercises are methodically designed in the proven format of math games. This enhances motivation and facilitates the use of self-assessment for internal differentiation, in support lessons, in weekly plans, during independent work, and in mixed-age classes. The math games can be used independently of textbooks, are easy to understand, and are therefore ideally suited for organizing substitute lessons.
