• 7 hidden word puzzles
• Great for starters, early finishers, revision or as fun homework tasks

 
ROUNDING GAMES:

• These dice games make students think carefully about where to place digits in order to make each statement on the board correct. As children are allowed to place the digits they roll (or spin) in any row on their side of the board, they will begin to generate tactics and the uncertainty will be prolonged until the final moments!
• Many levels of challenge - ideal for differentiation or for use across year groups: includes multiple games for each of rounding to the nearest ten, hundred, thousand, whole number, one decimal place, two decimal places, estimating the sum or difference and one for rounding to the nearest ten thousand
• Use as printed worksheets or else laminate (or use in dry-wipe sleeves) and complete with whiteboard pens
• Instead of playing in pairs, you might form small groups - pairs could play against pairs instead of one-versus-one and you might appoint a checker who can adjudicate (and then swap roles for the next game). Consider enlarging to A3 for larger groups
• Instructions are printed on the board

 
If you don’t have a 0-9 dice:

• Use 0-9 spinners (I have included black and white and colour templates for your convenience) if you wish to make some
• Use digit cards (basic digit cards included in the file)
• Use a pack of playing cards (use Aces as 1 and Jacks as 0, put aside the Kings and Queens; shuffle the pack and take one card in turn)

 
ROUNDING HIDDEN WORD PUZZLES:

• 1 for rounding to the nearest ten
• 1 for rounding to the nearest hundred
• 1 for rounding to the nearest thousand
• 1 for rounding to the nearest whole number
• 1 for rounding to the nearest one decimal place
• 1 for rounding to the nearest two decimal places
• 1 for rounding money to the nearest pound (dollar version also included)

 
More about hidden word puzzles: Similar to codebreaker puzzles, with a maths-related word to be revealed after the rounding work. Each puzzle contains a grid. Within each box is a number to be rounded and a letter. Once students have rounded all the numbers, they cross out any boxes containing numbers that round to certain specified target numbers. Then they put together the letters from the remaining boxes to reveal a maths word. If the word is more simple, the letters are in random order for students to reassemble. If it is a trickier word (such as a famous mathematician), the letters are already placed in the correct order in the grid. There is a further challenge question / task at the bottom of the page linked to the hidden word.
