• Place value models: This worksheet helps your 4th grader understand the value of each digit in a multi-digit number by using base-ten blocks and expanded form. For example, 3,456 can be represented as 3 thousands, 4 hundreds, 5 tens, and 6 ones or as 3 x 1000 + 4 x 100 + 5 x 10 + 6 x 1.
• Convert between place values: This worksheet helps your 4th grader practice converting between different place values, such as thousands, millions, and billions. For example, how many thousands are in 6 million? How many millions are in 9 billion?
• Identifying place value names: This worksheet helps your 4th grader recognize the names of different place values, such as ones, tens, hundreds, thousands, etc. For example, what is the name of the place value of the digit 7 in 7,654,321?
• Writing numbers up to billion in words: writing from words to numbers: This worksheet helps your 4th grader practice writing numbers up to one billion in standard form given their word names. For example, write four hundred fifty-six million three hundred twenty-one thousand seven hundred eighty-nine in standard form.
• Writing numbers up to billion in words: convert numbers to words: This worksheet helps your 4th grader practice writing numbers up to one billion in word form given their standard form. For example, write 456,321,789 in word form.
• Spell word names: review: This worksheet helps your 4th grader review spelling the word names of numbers up to one billion. For example, spell out the number seven hundred sixty-five million four hundred thirty-two thousand one hundred ninety-eight.
• Roman numerals: This worksheet helps your 4th grader learn how to read and write Roman numerals up to M (1000). For example, write XLVII in standard form. Write 198 in Roman numerals.
• Prime and composite: up to 100: This worksheet helps your 4th grader identify prime and composite numbers up to 100. A prime number is a number that has only two factors: one and itself. A composite number is a number that has more than two factors. For example, is 17 a prime or composite number? Is 36 a prime or composite number?
• Rounding: up to the millions place: This worksheet helps your 4th grader practice rounding numbers up to the millions place to the nearest ten, hundred, thousand, ten thousand, hundred thousand, or million. For example, round 3,456,789 to the nearest hundred thousand.
• Rounding input/output tables: This worksheet helps your 4th grader apply rounding rules to complete input/output tables. For example, what is the output if the rule is round to the nearest ten and the input is 45?
• Even or odd: arithmetic rules: This worksheet helps your 4th grader use arithmetic rules to determine whether a number is even or odd. An even number is a number that can be divided by two with no remainder. An odd number is a number that cannot be divided by two with no remainder. For example, is 2 + 3 even or odd? Is 4 x 5 even or odd?
• Inequalities with number lines: This worksheet helps your 4th grader use number lines to compare and order numbers using inequality symbols (<, >, =). For example, which symbol makes this statement true: 5 ___ 7? Use a number line to show your answer.
• Compare numbers up to one billion: This worksheet helps your 4th grader compare and order numbers up to one billion using place value and inequality symbols. For example, which number is greater: 345,678,901 or 346,789,012? Use inequality symbols to show your answer.

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!
• Place value war: Use a deck of cards to play a game of war with a twist. Each player draws four cards and arranges them to make the largest possible four-digit number. 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.
• Prime or composite race: Write some numbers up to 100 on index cards and shuffle them. Divide your 4th grader into two teams and have them take turns picking a card and saying whether it is prime or composite. If they are correct, they keep the card. If they are wrong, they put it back in the pile. The team with the most cards at the end wins.
• Rounding relay: Set up a relay race with four stations, each with a different rounding rule (round to the nearest ten, hundred, thousand, or million). Have your 4th grader run from station to station and round the numbers you give them according to the rule. The first one to finish all four stations wins.
• Even or odd hopscotch: Draw a hopscotch grid on the ground and write some even and odd numbers in each square. Have your 4th grader hop on the even or odd numbers, depending on what you say. You can also have their say on whether each number is even or odd as they hop.
• Inequality challenge: Write some numbers up to one billion on slips of paper and put them in a bowl. Have your 4th grader draw two slips of paper and compare the numbers using inequality symbols. If they are correct, they get a point. If they are wrong, they lose a point. The one with the most points at the end wins.
• Compare and order: Write numbers up to one billion on sticky notes and stick them on a wall or board. Have your 4th grader arrange them in ascending or descending order, depending on what you say. You can also have them use inequality symbols to show how they compare.
• Number sense jeopardy: Create a jeopardy board with five categories related to number sense, such as place value, rounding, prime and composite, even and odd, and inequalities. 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. If they are correct, they get the points. If they are wrong, they lose the points. The one with the most points at the end wins.
• Number sense quiz: Create a quiz with multiple choice, true or false, fill in the blank, or short answer questions related to number sense. Have your 4th grader take the quiz and check their answers. You can also have them make their quiz and exchange it with a friend.

These activities will make learning number sense fun and exciting for your 4th grader!

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 problem-solving skills.
• Use manipulatives or visual aids to help your child understand abstract concepts. For example, you can use base-ten 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 twenty-three, 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.
