In math, students in grades 3-6 typically build on the basic concepts and skills they learned in earlier grades. During this period, they further develop their understanding of numbers, operations and problem-solving strategies. Here are some key topics and skills students typically learn in math in grades 3-6:

Number and Operations:

Place value: understanding the value of digits in multi-digit numbers and their positions.
Operations: addition, subtraction, multiplication and division of whole numbers, fractions and decimals.
Estimate: approximate and rounded numbers.
Factors and multiples: identifying factors and multiples of numbers.
Prime and composite numbers: understanding the concepts and identifying examples.

Fractions and Decimals:

Comparing and ordering fractions and decimals.
Adding, subtracting, multiplying and dividing fractions and decimals.
Converting between fractions and decimals.
Understanding equivalent fractions.

Geometry:

Lines, angles and shapes: identify and classify different geometric shapes.
Perimeter and area: calculate perimeter and area of polygons.
Symmetry: identify lines of symmetry and shapes.

Measurement:

Length, weight, and capacity: estimate, measure, and convert units.
Time: read analog and digital clocks, calculate elapsed time.
Money: identify and count coins and bills, change.

Data and Probability:

Gathering and organizing data: constructing and interpreting tables, charts, and graphs.
Probability: understanding basic concepts and probability, such as probability and chance.

Solving a problem:

Analyzing and solving word problems using various mathematical strategies.
Applying arithmetic operations to real-life situations.
Developing critical thinking and logical reasoning skills.
In addition, students also focus on developing mathematical fluency, improving mental mathematical skills and promoting a deeper understanding of mathematical concepts. They engage in hands-on activities, problem-solving tasks and mathematical discussions to reinforce their learning. The curriculum may vary slightly depending on the education system and the specific textbooks used in each region or school.
