2nd Grade Math Competition Test
Level 1 Challenge (10 Questions)
*Note: The visual diagrams to Questions to 1, 4, and 9 are below.*
1. Shapes Comparison: With how many more are the triangles than the squares?
2. Arithmetic Calculation: Calculate: $(100 – 57) + 0 – (96 – 78)$
3. Sides and Edges Total: How many sides and edges in total do two rectangles, one square, and three triangles have?
4. Perimeter and Path: The ant walked two times on the path ABCA (ABC is an equilateral triangle). The turtle walked on an Isosceles triangle MEK on the following path MEKME. By how many metres did one of the animals walk longer than the other one?
5. Ribbon Lengths: Iva bought ribbons: four with length 4dm and 18 cm, two of 4 dm, one 6 dm, 3 – 57 cm and one 7 dm. How many of the ribbons are longer than 53 cm?
6. Set Theory: The father of Jane participated in two movies. Her mom in one of those movies and in two other movies. Her brother participated in one movie together with his parents, in two movies alone and in one movie together with one of his parents. In how many movies participates at least one of Jane’s relatives?
7. Time and Intervals: Ani does 3 groups of exercises. In every group there are 5 exercises. Each exercise takes 4 minutes. Between each group exercises Ani takes a break of 3 minutes. How many minutes after Ani started, she will finish her last exercise?
8. Perimeter Application: The numbers 12, 8, 18, 4, 5, 20 (in cm) are the perimeters in cm of an equilateral triangle, a square and an isosceles triangle with base 1 cm. What is the side of the isosceles triangle?
9. Pyramid Sums: After replacing letters with digits in the pyramid (the visual for the pyramid is missing), calculate the result of (A+B+C) − (D+E+F+G+H+I+К)?
10. Sequence, Days, and Money: Elias made on Monday 3 toys for the Christmas tree. Each day afterwards, he made one more toy than the day before until he made 63 toys in total. A: On how many days did he work? B: In which day of the week, did he stop working? C: He packed the toys 9 in a box. How many boxes did he use? D: He left one box for himself, gifted 1 to each of her 3 friends and the rest he sold on the Christmas market. For one box, he got 11 leva and for the rest 14 leva each. How much money did he get?
*This is a multi-part question and cannot be auto-graded. Please solve it separately.*


Math Vocabulary to learn
Perimeter – Обиколка – The perimeter of a triangle.
Circumference – Окръжност – The circumference of a circle.

📐 Names of Triangles
| Classification System | Triangle Name (English) | Translation (Български) | Defining Property |
| By Sides | Equilateral triangle | Равностранен триъгълник | All 3 sides are the same length. |
| Isosceles triangle | Равнобедрен триъгълник | At least 2 sides are the same length. | |
| Scalene triangle | Разностранен триъгълник | No sides are the same length. | |
| By Angles | Right triangle | Правоъгълен триъгълник | Has one $\mathbf{90^\circ}$ (right) angle. |
| Acute triangle | Остроъгълен триъгълник | All three angles are acute (less than $90^\circ$). | |
| Obtuse triangle | Тъпоъгълен триъгълник | Has one obtuse (greater than $90^\circ$) angle. |
Core Descriptive Terms
2nd graders are expected to be able to analyze and compare shapes using the following attributes:
- Vertices (or “Corners”)
- Sides
- Faces (for 3D shapes like cubes, cones, cylinders)
- Closed vs. Open
- Equal Sides (They start discussing if all sides or angles are the same).

2nd Grade Geometry Terms
| Shape | Sides/Angles | Key Terminology Students Should Know |
| Triangle | 3 sides, 3 angles (vertices) | Sides, Vertices (or corners), Closed (it’s a finished shape), 3-sided figure. |
| Quadrilateral | 4 sides, 4 angles | Quadrilateral (general term), Sides, Vertices. They should recognize examples like squares, rectangles, and rhombuses as all being quadrilaterals. |
| Pentagon | 5 sides, 5 angles | Sides, Vertices, 5-sided figure. |
| Hexagon | 6 sides, 6 angles | Sides, Vertices, 6-sided figure. |
| Cube | 6 faces, 12 edges, 8 vertices | Faces (flat surfaces), Edges, Vertices. They should know this is a 3D shape. |
| Circle | 0 sides | Curve, Round, No vertices. |
