Scramble squares are a little invention of mine (I think). I created them as a task to enable my first year 6 class to check their calculations using the inverse and calculators. The principle is simple - children create calculations using a a pair or several of the numbers, or they can use the numbers alongside external values.
For example, this Scramble Square could be used by year 3 to create column addition and subtraction questions. It could also be used to create multiplication questions by multiplying each number by a number from a 10-sided dice.
In another example, the Scramble Square below could be used by year 5 to convert decimals to fractions, or by year 4 to round numbers with one decimal place to the nearest whole number.
I hope you find these useful. The benefit of scramble squares is that children are enabled to choose their own calculations rather than looking at a worksheet. In the past, I have found that this has encouraged those children who get bored and distracted, simply because they are excited to decide their own path.
