The Polish podstawa programowa sets its requirements for the end of klasa III, not year by year. Schools break it down roughly like this.
Klasa I, around age seven
- Counting forwards and backwards, reading and writing numbers to 20, then to 100
- Adding and taking away inside 20, fluently inside 10
- Comparing numbers: more, less, the same
- Naming a square, a rectangle, a triangle and a circle
- Telling the time on the hour, then the half hour
Klasa II, around age eight
- Adding and taking away inside 100
- The times table begins, usually 2, 5 and 10 first
- Money: zลoty and grosze, and giving change
- Measuring in centimetres and metres; the perimeter of a rectangle
- The clock to five minutes
Klasa III, around age nine
- The whole times table, and dividing with it
- Numbers to 1000
- Two-step word problems
- Grams and kilograms, litres, the thermometer
What comes later
Fractions, angles and area belong to klasa IV. A child who is ahead can meet them early โ there is no harm in it โ but they are not a gap at seven.
How to check without a worksheet
Ask at the shop: what will we pay for these two things, and what change should we get? Ask at the table: there are twelve pierogi and four of us, how many each? A child who can do that in their head has the skill; a child who reaches for paper on "12 รท 4" needs the times table, not more addition.
What the evidence says about drilling
Retrieval practice โ being asked and having to recall โ beats re-reading or re-copying, both immediately and a week later. Timing the retrieval adds nothing and, at this age, adds anxiety. So ask often, keep it short, and leave the stopwatch out of it.
