Now also 5 and 10 minutes!

The kids of het Atelier have a first. They've been able to put us to work. Great initiative, boys and girls! That's why we can now also do 5- and 10-minute sums. That's a nice challenge if you're already very fast at 4 minutes.

"Tempotoets" = speedtest. They are used in the dutch elementary school system to monitor the progress of the pupils in their knowledge and usability of the "tables".
