In Smartick, we recommend avoiding the use of paper and a pencil to complete exercises. If children complete exercises this way, their agility, and mental calculation will not be exercised in the same way.
For example, if we have an exercise such as 55 + 23 and a student copies it on a piece of paper vertically, they will not be working on the same addition strategies as they would solving it horizontally.
Of course, there are certain exercises in Smartick that will require intermediate operations, and for those, we offer an on-screen grid in which the student can show their work.
