Word scramble
Unscramble the letters and write each key term on the line.
1
DDA EWN ULER
Each extra conditional formatting rule links one more number to one more colour, so one grid of numbers can show many colours.
2
1 = LACKB, 0 = EHWTI
A rule for a grid of cells: type 0s and 1s, then fill each 1 black and each 0 white so the code shows as a picture. Change one digit to change one pixel.
3
ILPXE RAT
A picture made of coloured squares. In a spreadsheet, you type a whole-number colour code in each cell and formatting rules turn each number into its colour.
4
DEOCNE
To ______ a word, swap each letter for its number in the code, so with A=1, B=2 and C=3, CAB becomes 3 1 2. To decode it, swap each number back for its letter.
5
RYANBI OCED
A pattern of 0s and 1s, like a thread of two bead colours. Every letter has its own pattern, so a computer can store text as 0s and 1s.
6
TADA PEYT
The kind of data a value is, such as a number, text or true/false. The ______ decides what the computer can do with the value.
7
HOEWL MNEUBR
A number with no fraction or decimal part, like 0, 7 or 250. We use whole numbers to count things, such as scores, lives or students. 3.5 is not a ______.
8
ISRGNT
A ______ is text: a row of characters such as letters, digits, symbols and spaces, written inside quote marks like "cat". Even "5" is a ______.
9
ABELONO
A data type with only two possible values: true or false. It stores the answer to a yes/no question, like 'is the light on?', just like on and off in binary.
Answer Key

1DDA EWN ULER → Add new rule — Each extra conditional formatting rule links one more number to one more colour, so one grid of numbers can show many colours.
21 = LACKB, 0 = EHWTI → 1 = black, 0 = white — A rule for a grid of cells: type 0s and 1s, then fill each 1 black and each 0 white so the code shows as a picture. Change one digit to change one pixel.
3ILPXE RAT → pixel art — A picture made of coloured squares. In a spreadsheet, you type a whole-number colour code in each cell and formatting rules turn each number into its colour.
4DEOCNE → encode — To encode a word, swap each letter for its number in the code, so with A=1, B=2 and C=3, CAB becomes 3 1 2. To decode it, swap each number back for its letter.
5RYANBI OCED → binary code — A pattern of 0s and 1s, like a thread of two bead colours. Every letter has its own pattern, so a computer can store text as 0s and 1s.
6TADA PEYT → data type — The kind of data a value is, such as a number, text or true/false. The data type decides what the computer can do with the value.
7HOEWL MNEUBR → whole number — A number with no fraction or decimal part, like 0, 7 or 250. We use whole numbers to count things, such as scores, lives or students. 3.5 is not a whole number.
8ISRGNT → string — A string is text: a row of characters such as letters, digits, symbols and spaces, written inside quote marks like "cat". Even "5" is a string.
9ABELONO → Boolean — A data type with only two possible values: true or false. It stores the answer to a yes/no question, like 'is the light on?', just like on and off in binary.
