The examination is a daunting experience for many of us. Also, if it is an upcoming mathematics board examination, we really want to put our best forward on the answer scripts. MP Board Class 10 Mathematics as a subject, perhaps is like a break from all the other subjects. In a subject like History, we have to make a conscious effort to remember the year in which a particular battle was fought or remembering Mendel’s law of inheritance as in Biology. Just a couple of formulae in mathematics and we are good to go. To understand the marking scheme and exam pattern, students can also refer to the mp board 10th blueprint 2020.
Following is the 2020-2021 syllabus for MP board 10th class:

|Unit 5|| Geometry
1. Triangles Periods-15
Definitions, examples counterexamples of similar triangles.
1. (Prove) if a line is drawn parallel to one side of 2 niangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.
2. (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.
3. (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.
4. (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.
5.(Motivate) If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.
6. (Motivate) If a perpendicular is drawn from the vertex of the right angle to the hypotenuse, the triangles on each side of the perpendicular are similar to the whole triangle and to each other.
7. (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the squares on their corresponding sides.
8. (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the squares on the other two sides.
9. (Prove) In a triangle, if the square on one side is equal to the sum of the squares on the other two sides, the angles opposite to the first side is a right triangle.
2. Circles Periods-6
Tangents to a circle motivated by chords drawn from points coining closer and closer to the point.
I. (Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact.
2. (Prove) The lengths of tangents drawn from an external point to a circle are equal.
3. Constructions Periods- 8
1. Division of a line segment in a given ratio (internally).
2. Tangent to a circle from a point outside it.
3. Construction of a et-bogie similar to a given triangle.
1. Areas Related to Circles Periods-12
Motivate the area of a circle; area of sectors and segments of a circle. Problems based on areas and perimeter/circumference of the above said plane figures.
(In calculating area of segment of a circle, problems should be restricted to central angle of . Plane figures involving triangles. simple quadrilaterals and circle should be taken.)
2. Surface Areas and Volumes Periods-12
|Unit 7||Statistics and Probability
1. Statistics Periods-15
Mean, Median and mode of grouped data (bimodal situation to be avoided). Cumulative frequency graph
2. Probability Periods-10
Classical definition of probability. Connection with probability as given in Class IX. Simple problems on single events, not using set notation.
|Appendix||1. Proofs in Mathematics
Further discussion on the concept of ‘statement’, ‘proof’ and ‘argument’. Further illustrations of deductive proof with complete arguments using simple results from arithmetic, algebra and geometry. Simple theorems of the “Given and assuming… prove ….. …”. Training of using only the given facts (irrespective of their truths) to arrive at the required conclusion. Explanation of ‘converse’, ‘negation’, constructing converses and negations of given results/statements.
2. Mathematical Modelling
Reinforcing the concept of mathematical modelling, using simple examples of models where some constraints are ignored. Estimating probability of occurrence of certain events and estimating averages may be considered. Modelling fair instalments payments, using only simple interest and future value (use of AP).
