NIOS Class 10 Mathematics 211 Practical Files are the one part of the course where you can pick up almost full marks without touching a single tricky sum. Every activity in the file is a hands-on demonstration, not a theory answer. The catch is neatness and completeness. Examiners want a tidy record with proper figures, correct steps and a clean conclusion for each experiment, and that is exactly where a properly made file pulls your aggregate up.
We prepare these files by hand for students who simply do not have the time, the drawing instruments or the confidence to sit and reproduce eleven geometry and algebra activities on ruled and graph paper. What you see below is the real thing: the actual experiment list, a fifteen-page sample from a finished file, and an honest explanation of how we build each one.

What You Get in the NIOS Class 10 Mathematics 211 Practical Files
When you order from us, you receive a complete, ready-to-submit NIOS Class 10 Mathematics 211 Practical Files record, not a rough draft you still have to copy. The index is filled in, every experiment is written out in order, and the figures are drawn and coloured the way NIOS activities expect. You just add your name, enrolment number and dates, and carry it to your study centre.
Each of the eleven activities carries the standard NIOS structure so nothing looks improvised: a clear title, the expected background knowledge, the objective, the materials list, the preparation steps, the demonstration or working, and a one-line conclusion. That fixed structure is what a checker scans for, and a file that follows it top to bottom rarely loses presentation marks.
The record is genuinely written by hand, not printed to look handwritten. Algebra identities use coloured glaze-paper squares and rectangles pasted in place, graph activities use real graph paper with plotted points, and the geometry proofs use folded and cut triangles exactly as the lab manual describes. If you have already browsed our wider NIOS Class 10 Practical Files collection, this Mathematics file is built to the same finish.
All 11 Experiments Covered in the Mathematics 211 Practical File
This is the actual list of activities inside the file, in the order they appear. We have paired each one with the concept it demonstrates and the material it uses, so you can see straight away that no two experiments repeat the same idea. Every row is a different chapter of your syllabus doing real work on paper.
| No. | Experiment (as written in the file) | Concept it demonstrates | How it is shown in the file |
|---|---|---|---|
| 1 | Verification of the identity (a + b)² = a² + 2ab + b² | Special products and factorisation | A square of side (a + b) split into one a-square, one b-square and two a-by-b rectangles in different colours |
| 2 | Verification of the identity (a − b)² = a² − 2ab + b² | Special products, subtraction form | A large a-square with two rectangles and a small b-square removed to leave the (a − b) square |
| 3 | Verification of the identity (a² − b²) = (a + b)(a − b) | Difference of two squares | A b-square cut from an a-square, then the leftover region rearranged into a single (a + b) by (a − b) rectangle |
| 4 | To find the HCF of two given numbers by the division method | Number systems and divisibility | Cardboard strips of length 32, 20, 12, 8 and 4 cm laid against each other to reach the HCF of 4 |
| 5 | To verify that a linear equation in two variables has infinite solutions | Linear equations in two variables | The line 2x − y = 6 plotted on graph paper, with several ordered pairs checked to show they all lie on it |
| 6 | To verify graphically that a quadratic polynomial can have at most two zeroes | Polynomials and quadratic equations | Parabolas for x² − 5x + 6, 4 − 3x − x², x² − 6x + 9 and x² − 4x + 8 drawn to show two, one and no real zeroes |
| 7 | To verify that the sum of the angles of a triangle is 180° | Lines and angles | The three angles of a paper triangle cut off and rearranged to form one straight angle |
| 8 | To verify that angles opposite to equal sides of a triangle are equal | Congruence of triangles | An isosceles triangle folded along its median so the two base angles fall exactly on each other |
| 9 | To verify the mid-point theorem | Quadrilaterals and parallel lines | Mid-points of two sides joined, then the small triangle superposed to form parallelogram PQRB showing PQ is parallel to and half of BC |
| 10 | To verify the Pythagoras theorem | Similarity and right triangles | A square of side (a + b) with a tilted inner square and four congruent triangles, arriving at c² = a² + b² |
| 11 | To find the area of a circle | Perimeter and area of a plane figure | Coloured threads wound as concentric circles, then cut and laid out into a triangle to reach the area πr² |
Notice that the file spans five of your six modules in one go: algebra through the three identities and the HCF activity, geometry through the triangle and mid-point proofs, and mensuration through the area of a circle. Preparing it carefully quietly revises a big slice of the theory paper too. For the full topic-wise breakdown, our NIOS Study Material section maps each of these activities back to its lesson.
Sample Pages From Our Mathematics 211 Practical File
So you are not buying blind, here is a fifteen-page preview taken straight from a completed file. These are the first fifteen pages of the record, covering the three algebra identities, the HCF activity, the linear-equation graph, the quadratic-polynomial graphs and the angle-sum proof. The rest of the file finishes the geometry proofs and the area of a circle, and is shared once you order.

How We Prepare Each Handwritten Mathematics 211 Practical File
We do not template these files or photocopy an old one and swap the name. Each order is written afresh, because handwriting, ink shade and the little imperfections in a hand-drawn parabola are exactly what tell a checker the work is a student's own. A file that looks mass-produced invites more questions, not fewer.
The algebra identities are the fiddliest part, and we take our time with them. The coloured squares and rectangles are cut to real measured sizes, so when the figure claims a side of 7 cm and 4 cm, the paper actually measures that. The area sums then match the drawing, and the conclusion reads honestly instead of being forced.
Graph work is done on proper graph paper, never freehand on ruled lines. Points for 2x − y = 6 and for each quadratic are plotted from a worked table, so the curve passes through the right places and the zeroes sit where the algebra says they should. Small touches like this are the difference between a file that scores and one that merely exists.
Every activity we build follows the same official sequence used across the NIOS Solved Lab Manual, so your Mathematics file sits comfortably next to files for your other practical subjects without looking out of place.
Mathematics 211 Syllabus Chapters Behind Every Practical

If you are still mapping out what to study this year, keep the full NIOS Class 10 Syllabus open beside your file. Seeing the practical activity and its parent lesson side by side is one of the quickest ways to make the theory stick.
Why the Mathematics 211 Practical File Decides Your Practical Marks
Practical and internal assessment carry real weight in your final Mathematics result, and unlike the theory paper, this is score you fully control in advance. A neat, complete file walks in as evidence before you even speak. A thin or half-finished one puts you on the back foot from the first page.
Checkers move quickly through a stack of files, so first impressions matter. A filled index, consistent headings, coloured figures and a signed conclusion on every activity signal a student who did the work seriously. That impression tends to carry through the whole viva, not just the file marks.
There is a quieter benefit too. Because the activities pull from algebra, geometry and mensuration, sitting with a well-made file is genuine revision. Students who actually read their own file before the exam often walk into the theory paper recognising the identities and the mid-point theorem instead of meeting them cold.
How to Order Your NIOS Class 10 Mathematics 211 Practical Files
Ordering is simple and there is no long form to fill. Message us on WhatsApp, tell us your session and your medium, and we confirm the current price and the time we need to prepare and dispatch the file. Once you approve, the handwritten record is made, checked and sent to you ready for submission.
We take orders for the 2026 session now, and it helps to reach out early. A hand-built file takes real hours, and the weeks close to submission are always the busiest. Booking ahead means your NIOS Class 10 Mathematics 211 Practical Files reach you with room to spare rather than in a last-minute rush.
Who Prepares Your Mathematics 211 Practical File at Unnati
Unnati Education has worked with NIOS learners since 2010, across Secondary and Senior Secondary streams. We are an independent academic-support platform, so our whole focus is on getting open-schooling students through their files, assignments and exams with as little stress as possible.
The Mathematics files are drawn up by our subject team and checked by our NIOS counsellors before dispatch, so what reaches you is both mathematically correct and presentation-ready. If a figure or a step ever looks off to you, we would rather you tell us and we fix it than have you submit something you are unsure about.

FAQs on the NIOS Class 10 Mathematics 211 Practical File
How many experiments are in the Mathematics 211 practical file?
The Mathematics 211 practical file contains eleven activities in total. These run from three algebra identities and an HCF activity, through graph-based work on linear and quadratic equations, into geometry proofs on triangles and the mid-point theorem, and finish with the Pythagoras theorem and the area of a circle. All eleven are solved and written out in the file we send you.
Is the Mathematics 211 practical file handwritten or printed?
Every Mathematics 211 practical file we supply is genuinely handwritten, not printed to imitate handwriting. Figures are drawn and coloured by hand, graphs are plotted on real graph paper, and the algebra identities use measured paper cut-outs pasted in place. This is exactly the finish a NIOS checker expects, which is why hand-built files tend to hold their presentation marks.
Can I see a sample before I buy the Mathematics 211 practical file?
Yes, and you already can. The preview above shows fifteen real pages from a completed Mathematics 211 practical file, covering the three algebra identities, the HCF activity, the graph work and the angle-sum proof. If you would like a closer look at any specific activity before ordering, message us on WhatsApp and we will share more detail.
Which chapters does the Mathematics 211 practical file cover?
The activities in the Mathematics 211 practical file draw from five of the six modules. Algebra supplies the identities and the HCF work, geometry supplies the triangle and mid-point proofs, and mensuration supplies the area of a circle. That means preparing the file quietly revises a wide slice of the syllabus rather than one isolated corner of it.
How long does it take to get the Mathematics 211 practical file?
Because each Mathematics 211 practical file is written by hand, we usually need a few days to prepare, check and dispatch it. The exact timing depends on how busy the session is and your delivery location, so we confirm both the price and the turnaround on WhatsApp before starting. Ordering well before your submission date is always the safest choice.
Is the Mathematics 211 practical file ready for the 2026 session?
Yes, the Mathematics 211 practical file is prepared for the 2026 practical exam and follows the current activity structure. We keep the format aligned with what study centres are accepting this session. If your centre has given you a specific instruction sheet, share it when you order and we will match the file to those exact requirements.
