Numbers & letters
The left hand for numbers, the right for letters: sort them on screen, connect them alternately (1-A-2-B) and a worksheet on which both hands write at the same time. ← All concentration exercises
How it works
Pick a form
Sort: number left, letter right – with reaction time. Connect: 1 – A – 2 – B … in order. Both hands: one sheet for both hands at once.
Practise
On screen the exercise counts time and errors and remembers your rounds. On Medium and Hard every sign has a time limit when sorting.
“Connect” and “Both hands” come as worksheets – both hands in three levels: trace, continue and backwards.
Frequently asked questions
What is the two-handed exercise good for?+
Letting both hands write different things at the same time asks for coordination and divided attention. Many find it a good warm-up before studying or a change in therapy and care. Start slowly – accuracy before speed.
Where does connecting 1-A-2-B come from?+
Connecting numbers and letters alternately resembles the well-known Trail Making Test (part B). Here it is an exercise to practise switching and overview – without norm values and without diagnosis.
Which keys do I use when sorting?+
F (or arrow left) for numbers, J (or arrow right) for letters – so the index fingers of both hands are ready. On a phone you tap the two big fields.
Who are the sheets for?+
Easy (trace outlines) suits children and beginners, Medium (continue rows) pupils and adults, Hard (backwards) challenges the practised too. “Extra large print” makes the boxes bigger.
