# Math Workbook for 4th Grade. Part 3

Decimals; Fractions and mixed numbers; Equivalent fractions; Factors and prime factorizing; Integers; Rounding; Word problems; Area and perimeter; Lines, segments, rays, and angles; Triangles; Memory & logic

A feature of our workbooks is the symbiosis of mental arithmetic and classical mathematics.

Mental arithmetic represents a UNIQUE method of teaching children that trains the speed of perception and processing of information and allows them to harmoniously develop both hemispheres of the brain at the same time by mentally visualizing the calculations on the abacus. A developed brain provides a basis for successful subsequent activities.

With the help of our workbook «Math + MA: Part 3» children repeat the techniques for fast mental counting, counting on the abacus, multiplying and dividing multi-digit numbers, including division with a remainder, solving words, money, logic problems. Children learn to work with fractions and decimals: find equivalent fractions; convert improper fractions into mixed numbers; convert decimals into fractions or mixed numbers and vice versa; compare decimals; write and solve variable expressions with decimals; add and subtract decimals, like fractions, unlike fractions, and mixed numbers.

Children learn Integers numbers, learn to operate with Integers: add, subtract, compare Integers, convert a number into its expanded form, repeat place values and rounding, repeat order of operations, find an area and a perimeter of compound shapes.

In addition, students learn to prime factorize a number, find factors of a number, and work with table data. Plus, children acquire the beginning of Geometry: draw and name lines, line segments, rays; draw and measure angles; classify triangles.

Our colorful workbook and the style of providing exercises allow children to acquire the material easily and hassle-free. The workbook contains many problems that create positive motivation for learning and actively develop the logic, memory, attention, and intelligence of children.

The material consists of 10 lessons and additional homework exercises (116 pages).
