Because a worksheet tells you if you are wrong . KooBits teaches you why you are wrong and shows you how to fix it immediately.
Organized by Math Olympiad topics:
| Real Olympiad Topic | Covered in KooBits? | Depth Level | |---------------------|---------------------|--------------| | Logical reasoning (grid puzzles, lying/truth-tellers) | ✅ Fully | Intermediate to Advanced | | Number patterns & sequences | ✅ Fully | Advanced | | Combinatorics (combinations, permutations basics) | ✅ Partially | Basic to Intermediate | | Geometry (area, perimeter, angles, nets) | ✅ Fully | Intermediate | | Word problems (excess/shortage, work rate) | ✅ Fully | Advanced | | Number theory (divisibility, remainders, primes) | ✅ Partially | Basic only | | Invariants & extreme principle | ❌ Not covered | N/A | | Proof-based problems | ❌ Not covered | N/A | koobits math olympiad
The Fix: For every KooBits problem, force your child to draw the bar model on paper before clicking the answer. Olympiad graders require working steps. Because a worksheet tells you if you are wrong
: In a triangle $ABC$, $AB = 5$, $BC = 6$, and $AC = 7$. Find the length of the altitude from $A$ to $BC$. Solution : Using Heron's formula, we can find the area of the triangle: $K = \sqrts(s-a)(s-b)(s-c)$, where $s$ is the semi-perimeter. Then, we can use the formula for the area $K = \frac12 \cdot BC \cdot h$ to find the length of the altitude. Find the length of the altitude from $A$ to $BC$
