Number sense is the ability to understand and manipulate numbers in various ways. It involves recognizing patterns, relationships, and properties of numbers and using different strategies to solve problems involving numbers. Number sense is important for 4th graders because it helps them:
 Develop a sense of the magnitude and scale of numbers, such as knowing which number is bigger or smaller or how to round numbers to the nearest ten or hundred.
 Compare and order numbers up to one billion using symbols such as <, >, or =.
 Use place value to read, write, and represent numbers in different forms, such as standard form, expanded form, word form, or Roman numerals.
 Identify and classify numbers as prime or composite, even or odd, or multiples or factors of a given number.
 Use mental math skills to perform basic operations such as addition, subtraction, multiplication, and division.
 Apply number sense skills to other math domains such as fractions, decimals, measurement, data analysis, and geometry.
As you can see, number sense is essential for 4th graders to succeed in math and beyond. That's why we have selected these free printable 4th Grade number sense worksheets from Mathskills4kids.com, covering all the key number sense topics and skills for 4th grade.

10 fun and engaging number sense activities for 4th Grade
Worksheets are great for practicing number sense skills, but sometimes you should spice things up with fun and engaging activities that your 4th grader will love. Here are some ideas for number sense activities that you can do at home or in the classroom:
 Number bingo: Create a bingo card with numbers up to one billion in different place values, such as 3,000, 40,000, 500,000, etc. Call out the word names of the numbers and have your 4th grader mark the corresponding numbers on their bingo card. The first one to get five in a row wins!

Then, they compare their numbers using inequality symbols, and the player with the larger number wins all the cards. The game continues until one player has all the cards or no more cards are left.
 Roman numeral hunt: Write some Roman numerals on sticky notes and hide them around the house or classroom. Have your 4th grader find them and write them in standard form on paper. You can also have them write the Roman numerals for some numbers you give them.

Write some questions and answers for each category and assign different point values. Have your 4th grader choose a category and a point value and answer the question.

Tips and tricks to help your 4^{th} grader master number sense skills
Number sense is something that takes time to learn. It takes determination, practice, and exposure to different numbers and operations. Here are some tips and tricks to help your 4th grader master number sense skills:
 Encourage your child to use mental math strategies whenever possible. Mental math helps develop number sense by making connections between numbers and operations. For example, to add 47 and 36, your child can think of 47 as 50  3 and 36 as 40  4, and then add 50 and 40 to get 90, subtract 3 and 4 to get 7, and finally combine 90 and 7 to get 97.
 Play games that involve numbers and logic, such as Sudoku, KenKen, or Kakuro. These games challenge your child to use number sense skills such as place value, patterns, and operations to fill in the missing numbers in a grid. They also help improve your child's concentration, reasoning, and problemsolving skills.
 Use manipulatives or visual aids to help your child understand abstract concepts. For example, you can use baseten blocks, place value charts, or number lines to help your child learn about place value, rounding, or comparing numbers. You can also use fraction strips, pie charts, or bar graphs to help your child learn about fractions, decimals, or percentages.
 Expose your child to different ways of representing numbers, such as words, symbols, pictures, or models. For example, you can show your child how the number 123 can be written as one hundred twentythree, as CXXIII in Roman numerals, as a bundle of one hundred sticks and two tens and three ones, or as a place value model with one hundred in the hundreds place, two in the tens place, and three in the ones place.
 Ask your child questions that require them to explain their thinking or justify their answers. For example, you can ask your child how they solved a problem, why they chose a certain strategy, what they noticed about a pattern, or how they checked their work. This helps your child develop mathematical reasoning and communication skills.
