Second Grade Math Worksheets
When students start 2nd grade math, they should already have good comprehension of addition and subtraction math facts. Many second graders will be ready to start working with early multiplication worksheets, perhaps with the help of a Multiplication Chart, Multiplication Table or other memory aid.
Regardless, practice with math worksheets in second grade will help build solid math fact skills that a student will rely on for the rest of their studies in math. The 2nd grade math worksheets in this section include the core addition, subtraction, multiplication and (if they’re ready) division fact practice.
Additional topics for 2nd grade include writing numbers in expanded form, measurement, rounding and telling analog time. You will also find in this collection of 2nd grade worksheets word problems and worksheets that require students to supply missing operations in math problems.

Joseph Louis Lagrange
mathematician, astronomer and mechanic
Date of birth: January 25, 1736
Birthplace: Turin, Kingdom of Sardinia
Date of death: April 10, 1813 (age 77), Paris, First Empire
Biography
Lagrange was born on January 25, 1736 in Turin.
Due to the financial difficulties of the family, he was forced to start an independent life early. At first, Lagrange became interested in philology. His father wanted his son to become a lawyer, and therefore assigned him to the University of Turin. But a treatise on mathematical optics accidentally fell into the hands of Lagrange, and he began to enthusiastically study mathematical literature.
In 1755, Lagrange sent Euler (a Swiss, German and Russian scientist who made a significant contribution to the development of mathematics, as well as mechanics, physics, astronomy and a number of applied sciences) his work on isoperimetric properties, which later became the basis of the calculus of variations. In this work, he solved a number of problems that Euler himself could not overcome. Euler incorporated Lagrange’s praise into his work and (together with d’Alembert) recommended the young scientist to foreign membership in the Berlin Academy of Sciences (elected in October 1756).
In 1755, Lagrange was appointed as a teacher of mathematics at the Royal Artillery School in Turin, where, despite his youth, he enjoyed the fame of an excellent teacher. Lagrange organized a scientific society there, from which the Turin Academy of Sciences subsequently grew, publishes works on mechanics and the calculus of variations (1759). Here, for the first time, he applies analysis to the theory of probability, develops the theory of oscillations and acoustics.
In 1764, the French Academy of Sciences announced a competition for the best work on the problem of the motion of the moon. Lagrange presented a paper on the libration of the Moon (see Lagrange points), which was awarded the first prize. In 1766, Lagrange received the second prize of the Paris Academy for his research on the theory of the motion of the satellites of Jupiter, and until 1778 he was awarded three more prizes.
In 1766, at the invitation of the Prussian King Frederick II, Lagrange moved to Berlin (also on the recommendation of d’Alembert and Euler).
Here he first headed the Physics and Mathematics Department of the Academy of Sciences, and later became the President of the Academy.
In 1772 he was elected a foreign member of the Paris Academy of Sciences. The Berlin period (1766-1787) was the most fruitful in Lagrange’s life. Here he did important work in algebra and number theory, including the rigorous proof of several of Fermat’s assertions and Wilson’s theorem.
Analytical Mechanics was prepared in Berlin and published in Paris in 1788 and became the pinnacle of Lagrange’s scientific work. Hamilton called this masterpiece a «scientific poem». The basis of all statics is the so-called. the principle of possible displacements, the basis of dynamics is a combination of this principle with the d’Alembert principle. Generalized coordinates are introduced, the principle of least action is developed. For the first time since the time of Archimedes, a monograph on mechanics does not contain a single drawing, which Lagrange was especially proud of.
In 1787, after the death of Frederick II, Lagrange, at the invitation of Louis XVI, moved to Paris, where he was received with royal honors and became a member of the Paris Academy of Sciences (no longer a foreign member).
In 1795 the Normal School was opened, and Lagrange teaches mathematics there. In 1797, after the creation of the Polytechnic School, he taught there, taught a course in mathematical analysis. During these years, Lagrange publishes his famous interpolation formula for approximating a function by a polynomial. Publishes the book «Theory of Analytic Functions», without actual infinitesimals. In the same place, Lagrange gave the formula for the remainder term of the Taylor series, indicated the method of Lagrange multipliers for solving problems for a conditional extremum.
Napoleon liked to discuss philosophical questions with the delicate and ironic Lagrange. He granted Lagrange the title of count, the position of senator and the Order of the Legion of Honor.
Lagrange made significant contributions to many areas of mathematics, including the calculus of variations, the theory of differential equations, solving problems of finding maxima and minima, number theory, algebra, and probability theory. The finite increment formula and several other theorems are named after him. In two of his important works, The Theory of Analytic Functions (1797) and «On the Solution of Numerical Equations» (1798) — summarized everything that was known on these issues in his time, and the new ideas and methods contained in them were developed in the works of mathematicians of the 19th century.
Lagrange died on April 10, 1813, and was buried in the Paris Pantheon.
His works:
- Analytical mechanics
- Calculus of Variations
- Lagrange differential equation
- Mathematical analysis
- Finite increment formula
- Theory of analytic functions
- On the solution of numerical equations
- Lagrange multiplier method
Named after him:
- Crater on the Moon
- asteroid (1006) Lagrange, discovered in 1923 by the Soviet astronomer Sergei Ivanovich Belyavsky
- Streets in Paris and Turin
- Many scientific concepts and theorems in mathematics, mechanics and astronomy
- Lagrange’s name is included in the list of the 72 greatest scientists of France, placed on the first floor of the Eiffel Tower.

Four Reasons to Study Math in Grade 2
Development of logical thinking
Mathematics teaches you to analyze data, establish relationships and find the best solution.
These skills will help you cope with more than one life task.
Achieving success in any profession
The ability to operate with numbers is necessary not only for economists. Mathematics is necessary even in such creative professions as an architect and a photographer.
Increasing authority in your environment
At school, a child who understands mathematics will be respected by his peers, and outside of school he will not allow himself to be deceived, for example, at the checkout in a store.
Development of communication skills
It is not obvious, but it is a fact: those who are doing well with mathematics are more harmonious, logical and consistent in expressing their thoughts. This means that it is more pleasant to communicate with them.
What should mathematics be like for 2nd grade students?
Interesting problems instead of
long examples
Tasks are given in the form of a game. The student simply follows the course of an interesting story, like in a cartoon, and helps the plot move forward by solving simple and exciting mathematical logic problems.
Development of logic instead of operating with numbers
Mathematics teaches not only to count quickly, but also to think, reason, analyze and look for solutions based on logic. It is best to develop the necessary skills from childhood — they will be useful both in school and in life.
Lessons from just a few
minutes per day
Each lesson of the mathematics course lasts 30-40 minutes and is devoted to a separate topic.
The child can divide classes as convenient, doing at least 5-10 minutes a day, and return to tasks at any time.
