4th Grade Math Learning

At Fourth Grade, children enjoy exploring Math with fun Math activities and games. Children will enjoy completing these Math games and Free 4th Grade Math worksheets whilst learning at the same time.

During Fourth Grade, most children learn to round off numbers to the nearest 10, 100, 1000, 10000, 100000 or million. They are able to add columns of numbers together accurately, and subtract numbers proficiently. They show a good understanding of place value in relation to decimals, and can add and subtract decimals with up to 2 decimal places.

Children are able to multiply a range of whole numbers by one or two digits, and divide numbers by a single digit. They can use their multiplication table facts to answer related questions.

Children are able to compare fractions, and know how to work out equivalent fractions. They are able to solve multi-step problems involving whole numbers, fractions and decimals.
