Christmas Calculation (M/D/A/S) Code-Breaking Collection (KS2/KS3)

10 Printable Christmas-themed interactive code-breaking calculation challenge sheets that involve a fun way of using their answers to work out a code word that relates to Christmas in some way. Watch the video to see how the code works.

The pack includes 10 different code sheets:

Addition (4 digits) - Code word is presents
Division (2 digits divided by 1 digit) - Code word is chimney
Division (4 digits divided by 1 digit) - Code word is carols
Division (4 digits divided by 2 digits) - Code word is wreath
Multiplication (2 digits x 2 digits) - Code word is Santa
Multiplication (3 digits x 2 digits) - Code word is reindeer
Multiplication (3 digits x 2 digits) - Code words are wise men
Multiplication (4 digits x 2 digits) - Code word is stocking
Subtraction (4 digits - 3 digits and 4 digits - 4 digits) - Code word is sleigh
Subtraction (4 digits - 3 digits and 4 digits - 4 digits) - Code word is pudding

When the children work out the answer, they write the digits of the answers in cells. These digits are then added together to provide a total which in turn can be used to reveal a letter. It works really well for self-regulation of answers as they know if they aren’t getting letters that look like they will form words, they must have gone wrong somehow. With the answer sheet, you can also help them with individual questions easily.

Each sheet is interactive. They allow you to modify the title to personalise it, click on individual cells to reveal hints and clues and print the question sheet or answer sheet easily.

The codes are great or sharing amongst groups or working individually.

In the preview image, the questions have been blurred but are obviously unblurred in the paid versions.
