## Description

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

Mental arithmetic is 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 is a basis for successful future activities.

With the help of the workbook «Entertaining Math 7+: Part 4» children learn the techniques of quick mental counting and counting with abacus; practice to add and subtract vertically with and without regrouping; solve two steps word problems; compose and decompose a number into ones, tens, and hundreds; count money, make and solve money problems; solve one-step time problems. Also, children get to learn to determine and write the number of equal parts as a fraction, add and subtract like fractions, make equivalent fractions, find a fraction of a group. Students learn to round numbers to the nearest ten or hundred, learn to solve two-steps equations and inequalities, work with coordinate planes, find a perimeter and an area of two-dimensional shapes. Children learn to multiply numbers, make fact families, recognize even and odd numbers, read and use table data.

The colorful workbook and the style of having exercises in the form of games let children learn the material easily and hassle-free. In addition, the workbook contains a lot of funny pictures and interesting tasks that create positive motivation for learning and actively develop the logical thinking, memory, attention, and intelligence of children.
