🇳🇱 Made for the Dutch primary-school curriculum (groep 3–8). Lessons are in Dutch.

Why SlimSnap

Language and maths — both, and the link between them

Most apps do either language or maths. SlimSnap does both, because they meet: a child who reads a word problem but misreads the question solves the wrong sum.

📚

Language · 800+ lessons

Reading & language with strategy

From first letters to text analysis at test level.

Reading comprehension: main idea, purpose, summarising
Reference words, cause & effect, fact vs opinion
Spelling & grammar, verbs
Vocabulary with themes from daily life
Sentence analysis and word types

🧮

Maths · 160 lessons

From counting to fractions

And reading the problem counts too.

Numbers, counting, adding & subtracting
Times tables, division, written arithmetic
Clock, money, measuring and geometry
Fractions, percentages and decimals
Graphs, tables and word problems

On track all year

Not just group 8 — preparation for every test

Dutch schools test your child throughout the year to track progress. SlimSnap practises exactly those moments, from group 3 to the final test in group 8.

Around January · group 5–8

Final test (Doorstroomtoets)

48 reading practice tests · 16 boss exams · mid-year & end-of-year tests for reading and maths · full final-test preparation.

The real problem

Reads fluently but struggles with the test questions?

That’s logical. Reading comprehension does not improve by itself through “just reading more”. A child can read a text flawlessly aloud and still understand little of it. The strategies strong readers use automatically must be taught.

✓ Visuals with the language — scenes and diagrams show what a reference word points to.
✓ Concepts from daily life — new words connect to what your child already knows.
✓ Explain → practise → test — every strategy is modelled first.
✓ Help with every mistake — a short explanation, not just “wrong”.

The science behind it

Why children keep practising

Behind every reward and streak sits a proven learning principle. SlimSnap combines spaced repetition, adaptive difficulty, variable rewards and a growth-mindset coach — without addictive tricks.

• Owl mascot Snip encourages, comforts and celebrates.
• Streaks and milestones build a daily habit.
• Short sessions with a sleep-timer — meant to be finished.

Why SlimSnap

🗓️

All year, every test

Not just group 8. SlimSnap practises all school year — the mid-year and end-of-year tests and the final test.
