The printable "Secret Code Math" worksheets below cover dozens of different math topics, including addition, multiplication, division, and subtraction. Students first decode the numbers in the problems, then they solve.

To view the Common Core standards associated with any given lesson, click on the (CC) icon below any worksheet's description. On this worksheet, students will decipher the code to create 3-digit addition problems. Then they'll solve each one.
To solve these addition problems, students will first need to decipher the symbol addends.
This column addition worksheet has three addends. Each one has 2 or 3 digits.
These coded problems have up to 4 addends, with 2, 3, or 4 digits in each.
Subtraction
These secret code math subtraction problems each have 2-digits. Students do not borrow or regroup to solve.
Students will need to borrow/regroup to solve the subtraction problems on this sheet.
After decoding the numbers using the key, students will subtract to find the differences.
These 3-digit subtraction problems require students to borrow across zero. (example: 400-126)
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)
Rounding
Decode the numbers, then round each one to the nearest ten. (example: 264 rounds to 260)
On this one, children will figure out the numbers and then round to the nearest thousand.
Comparing Numbers
Decode sets of symbols into numbers. Compare each group with "greater than," "less than," or "equal to."
Use the symbols <, >, and = to compare each set of numbers.
Multiplication
Decode the factores. Then write the product for each basic multiplicaion fact, up to 10x10.
Write the product for each basic fact, up to 12x12.
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)
Solve the 3-digit multiplication patterns.
(example: 700 x 8)
Multiply 3-digit numbers by 1-digit numbers.
(example: 166 x 7)
Find the products by multiplying 4-digit numbers by 1-digit numbers.
(example: 3,478 x 4)
Here you'll multiply pairs of double-digit numbers together.
(example: 84 x 51)
Multiply 3-digit numbers by 2-digit numbers in this cypher-code activitiy.
Division
Convert the pictures into numbers, then write the quotient for each basic division fact.
For this activity, students will be solving problems that have 1-digit quotients with simple reminders.
These problems have 3-digit dividends, 2-dgit quotients, and no remainders.
This version has 3-digit dividends and 2-digit quotients. Each prolbme has a remainder.
