The safe addition and subtraction within the number range up to 100 is a significant challenge for many students with special educational needs. This means practicing, practicing, practicing. But how can you, as a teacher, offer your students variety beyond the same old routine? One way to do this is with one of the 24 simple and motivating math mandalas from this booklet. While working on the mandalas, students playfully practice solving addition and subtraction problems. In addition to their arithmetic skills, they simultaneously train their concentration, endurance, and hand-eye coordination. Moreover, coloring the mandalas has a relaxing and calming effect. With the help of the colored solution pages, students can also independently check if they have calculated correctly.
