This subtraction and addition up to 10 activity are great for improving mental maths skills. Kids have to add 1 or subtract 1 from 1-digit numbers.

In the first task students have to match answers and questions, in the second task they have to write the answer.

The cute topic of snails makes the tasks attractive. And the hidden background image has a positive effect on the motivation to do maths.

Only one look at the screens shows teacher how well students are doing on the tasks.
