Our series of workbooks for children 7 years old allows students learn to:

• form, name, read, write numbers from 0 to 1000
• compare numbers and record the result of the comparison
• order given numbers
• replace a two-digit number with the sum of bit terms
• perform addition and subtraction
• establish a pattern, or find a rule for a numerical sequence (increase/decrease a number by several units); continue a numerical sequence, restore the missing numbers
• group numbers according to a given or independently established attribute
• measure, read, and write a length of an object using units of length 
• read, write, determine the time on analog clocks with an accuracy of up to a minute, convert time units into each other
• use the ratio between the cent and the dollar and convert one into another

Using our workbooks every student learns to:

• group objects according to different characteristics
• independently choose a correct unit for measuring length, time, area and explain the choice.

In the section “ARITHMETIC AND MENTAL COUNTING”, students learn to:

• mentally add and subtract within 20
• perform addition and subtraction within 1000 vertically and check if the answer is correct
• name and denote the operations of multiplication and division
• replace multiplication as repeated addition
• multiply and divide by 10
• write and solve 2 steps numeric expressions, find their values
• use commutative and associative properties of addition
• solve simple equations
• reveal the specific meaning of the “multiplication” and “division”
• apply the commutative property of multiplication
• perform multiplication and division.

In the section “WORD PROBLEMS” students learn to:

• solve 1 or 2 steps problems using all four operators
• perform a brief record of the problem
• compose a word problem according to a drawing, a short note, or a numerical expression
• solve money problems

In the section “GEOMETRY” students learn to:

• name and draw geometric shapes: triangle, quadrilateral, circle, etc.
• build a rectangle (a square) with given side lengths with a ruler or on a checkered paper
• correlate real objects with models and drawings of a triangle, rectangle (square)
• find the length of an object using different units
• find the length of a polyline consisting of 3–4 links
• find a perimeter of a polygon (triangle, quadrilateral, pentagon)
• choose the most appropriate units of length in a particular situation

In the section “DATA AND GRAPHS” students learn to:

• read and fill the tables, graphs, picture graphs, and diagrams based on the results of the assignment
• conduct logical reasoning and draw conclusions
• understand the simplest statements with logical connectives: if …, then …; all; each and others
• find the true or false statements

Workbooks “Logic and out of the box thinking” for 7-9 years old

Parents are often looking for practices that help improve and develop the logical thinking and cognitive abilities of children. These skills increase intelligence and improve school performance. Logic is closely related to the exact sciences. The logical thinking of children needs stimulation in the same way as attention and observation.

It is necessary to develop logical thinking. It is an important quality that helps children in the future. Human society is illogical. People tend to make mistakes, repeat them, do stupid things in anticipation of a result, and get angry when it does not work out. A person who knows how to think logically stands out against the general background. Scientists have always been distinguished by impeccable logical thinking. Suffice it to recall Einstein and Edison. Thanks to this quality, they made their discoveries and changed science.

A person with developed logical thinking has important qualities:

• easily highlights the main statement and sweeps aside secondary ones
• accurately composes algorithms for achieving goals; speaks sensibly and consistently
• easily builds an evidence base, selects arguments
• builds coherent conclusions for persuasion.
