Before you print
What Level 1 is, and what it deliberately leaves out
The Level 1 practice sheet: single-digit addition and subtraction that needs no complement formulas at all, so every problem resolves to a direct bead movement. This is the stage a child works through before little friends are introduced. Answers are printed at the foot of the page.
The skill this sheet trains
Every one of the twenty four problems can be finished by moving beads that are free to move. Add 2 to a rod showing 1 and two lower beads go up. Take 3 from a rod showing 8 and three lower beads come down. Nothing needs to be exchanged, nothing needs to be borrowed, and the child never has to stop and think about what a number is short of. That constraint is the point. Level 1 is where hand technique is built: thumb up for the lower beads, index finger down, the upper bead handled by the index finger alone, and both hands still except the one doing the work. Get that right on easy arithmetic and the harder arithmetic later has one less thing to go wrong.
Using the sheet
Twelve additions then twelve subtractions, in that order, because subtraction on a real abacus is the harder direction and benefits from arriving second. Ten to fifteen minutes is normal. Finished means all twenty four correct against the key, and, more importantly, the same finger doing the same job every time. If you can only check one thing, watch the hands rather than the page.
What to watch for
The specific slip at this level is the child who is quietly working the sums in their head and using the abacus only to display the answer they already had. It is easy to miss, because the answers come out right and quickly. The tell is a hand that arrives on the rod once rather than twice. Small numbers make this cheat possible; at Level 2 it stops working and the child stalls, which is why it is worth blocking now.
Where it sits in the course
This is the first of the ten graded levels. It assumes a child can already read and set numbers on the frame and asks for nothing beyond that, which is exactly what level 1 covers.
What to print next
The first formula comes next, and it is small enough to learn in a week: Little Friends Addition.
