On this worksheet, students will decipher the code to create 3-digit addition problems. Then they'll solve each one.

2nd through 4th Grades

To solve these addition problems, students will first need to decipher the symbol addends.

2nd through 4th Grades

This column addition worksheet has three addends. Each one has 2 or 3 digits.

2nd through 4th Grades

These coded problems have up to 4 addends, with 2, 3, or 4 digits in each.

3rd through 5th Grades

These secret code math subtraction problems each have 2-digits. Students do not borrow or regroup to solve.

1st and 2nd Grades

Students will need to borrow/regroup to solve the subtraction problems on this sheet.

1st through 3rd Grades

After decoding the numbers using the key, students will subtract to find the differences.

2nd through 4th Grades

These 3-digit subtraction problems require students to borrow across zero. (example: 400-126)

2nd through 4th Grades

Translate the picto-code numbers into "regular numbers" and then solve. All problems require students to subtract 4-digit numbers across zero. (example: 5,000-2,614)

3rd and 4th Grades

Decode the numbers, then round each one to the nearest ten. (example: 264 rounds to 260)

2nd through 4th Grades

On this one, children will figure out the numbers and then round to the nearest thousand.

4th through 6th Grades

Decode sets of symbols into numbers. Compare each group with "greater than," "less than," or "equal to."

1st through 3rd Grades

Use the symbols <, >, and = to compare each set of numbers.

2nd through 4th Grades

Decode the factores. Then write the product for each basic multiplicaion fact, up to 10x10.

3rd and 4th Grades

Write the product for each basic fact, up to 12x12.

3rd and 4th Grades

First decode the numbers using the key at the top of the page. Then find the product for each pair of numbers.

(example: 54 x 6)

(example: 54 x 6)

3rd and 4th Grades

Solve the 3-digit multiplication patterns.

(example: 700 x 8)

(example: 700 x 8)

3rd through 5th Grades

Multiply 3-digit numbers by 1-digit numbers.

(example: 166 x 7)

(example: 166 x 7)

3rd through 5th Grades

Find the products by multiplying 4-digit numbers by 1-digit numbers.

(example: 3,478 x 4)

(example: 3,478 x 4)

4th and 5th Grades

Here you'll multiply pairs of double-digit numbers together.

(example: 84 x 51)

(example: 84 x 51)

4th and 5th Grades

Multiply 3-digit numbers by 2-digit numbers in this cypher-code activitiy.

4th through 6th Grades

Convert the pictures into numbers, then write the quotient for each basic division fact.

3rd and 4th Grades

For this activity, students will be solving problems that have 1-digit quotients with simple reminders.

3rd and 4th Grades

These problems have 3-digit dividends, 2-dgit quotients, and no remainders.

3rd through 5th Grades

This version has 3-digit dividends and 2-digit quotients. Each prolbme has a remainder.
