2. Topic Maths Aims  A variety of maths based exercises to be used as a warm up and ‘energiser’ at the beginning of a math lesson  Team work and group discussion is also encouraged  Worksheets can be collected at the end of the exercise to see who the winner is Level Level 2 Method  Paper/Electronic  Slides can be printed out to use as work sheets Equipment  PC/Laptop  Paper/Worksheets Duration 30 Minutes +

3. Place the numbers 1 to 9 (only once) in the boxes so each of the four lines of three boxes add up to 13 Discuss with each other a strategy to solve it

4. Discuss the statement by a Landlady to her tenant: “I don’t mind if you pay £50.00 a week or £200.00 per month just as long as I get it” Is there a difference? Can you show that there is a difference? Check with another Student £££££

5. Put in some missing operator signs (+,- to make the following sum work) 1 2 3 4 5 6 7 8 9 = 100 You can combine numbers in order e.g. the 3 and 4 can be 34, but you can not change the order

6. How many connections can you find between two or more of these numbers?

7. A) 58 B) 56 C) 746 These are the answers to three questions that only use the numbers 5, 6, 10, 25 and 73 once What could be the question

8. Identify as fast as possible, how many pairs of numbers have a difference of A) 10 B) 100 C) 1000

9. Draw and fill in a 4x4 grid with relevant number in each square ; for example you could put 9 in the first square Square Number Prime NumberMultiple of 5Even Number Multiple of 10Multiple of 3Ends in 1Triangular Number Greater than 120 3-digit NumberOdd NumberFactor of 30 Between 60 and 70 Cube NumberLess than 5First Digit is 2

10. Draw and fill in a 4x4 grid with relevant number in each square ; for example you could put 9 in the first square Square NumberPrime NumberMultiple of 5Even Number Multiple of 10Multiple of 3Ends in 1Has a 3 in it Greater than 120 3-digit NumberOdd NumberFactor of 30 Between 60 and 70 Middle digit is 9Less than 15First Digit is 2

11. Draw and fill in a 4x4 grid with relevant number in each square ; for example you could put 738 in the first square Prime Number greater than 50 Square Number greater than 144 Multiple of 7Divisible by 7, 11 and 13 A decimal number Factor of 75A Percentage greater than 30% Triangular number greater than 10 Less than minus 5 4-digit NumberOdd Number greater than 1000 Factor of 45 Between 80 and 120 A mixed number Bigger than one million First Digit is 7

12. Draw and fill in a 4x4 grid with relevant number in each square ; for example you could put 93871 in the first square Prime Number greater than 100 Square Number greater than 50 Multiple of 9Divisible by 7, 11 and 13 A decimal number to 5 decimal places Factor of 40A Percentage greater than 70% Triangular number greater than 10 Less than minus 25 5-digit NumberOdd Number greater than 1000 Factor of 88 Between 80 and 120 A very small number Less than one million First Digit is 9

13. Draw and fill in a 4x4 grid with relevant number in each square ; for example you could put 871 in the first square Proper FractionMixed NumberMultiple of 9Lowest common denominator of 3 and 7 A money amount over £10 Factor of 60A Percentage less than 70% Square number A negative number Top heavy fraction Odd Number greater than 1001 Factors of 17 A prime number3 digit numberOver one millionFirst Digit is 8

14. Using a 3x3 grid and the numbers 1 to 9 fill it in so the rows, columns, and diagonals, all add up to the same number What about a 5x5 grid using the numbers 1 to 25?
