Mathematics for Children: Age-by-Age Guide

Mathematics is often a source of worry for parents. Yet, with the right methods, every child can develop solid skills. Here's what you need to know by level.

Kindergarten - 1st Grade (5-6 years)

At this age, children discover the fundamental basics of mathematics through play and manipulation.

Skills to Acquire

  • Recognize numbers from 0 to 10
  • Count up to 30
  • Understand concepts of "more" and "less"
  • Recognize simple geometric shapes
  • Navigate in space (front, behind, above, below)

How to Help Your Child

Use everyday objects to count: toys, fruits, pencils. Board games with dice are excellent for number recognition.

2nd-3rd Grade (7-8 years)

Children enter calculation and simple problem-solving.

Skills to Acquire

  • Master addition and subtraction
  • Understand multiplication (tables of 2, 3, 5, 10)
  • Solve simple one-step problems
  • Tell time
  • Use a ruler to measure
  • Recognize flat geometric figures

How to Help Your Child

Multiplication tables require regular practice. Transform this learning into a game with timed challenges or songs.

4th-5th Grade (9-11 years)

The complexity level increases significantly.

Skills to Acquire

  • Master all multiplication tables
  • Long division
  • Fractions and decimals
  • Calculate perimeters and areas
  • Multi-step problems
  • Proportionality
  • Symmetry and angles

How to Help Your Child

At this level, accumulated gaps become problematic. An AI tutor like Akademos can precisely identify areas to work on and offer targeted exercises.

Common Mistakes to Avoid

  • Neglecting mental calculation in favor of calculators
  • Moving too quickly to abstract concepts without manipulation
  • Transmitting your own math anxiety to the child
  • Overloading the child with meaningless repetitive exercises
