Solution: If there were the same number of paperback and hardcover books, then this number would be half of 120 = 60. If we increase the number of hardback books by 10 then we must reduce the number of paperback books by 10, giving 70 and 50, with a difference of 20 books.
Week 1/ Term 3
Mrs Smith is redecorating her new office. One rectangular wall of Mrs Smith’s office contains a door and a window. Mrs Smith wants to paint this wall, but not the door or the window. The wall is 7m by 3m, the door is 2m by 1m, and the window is 2m by 1.5m. If each can of paint covers 4m squared, how many cans of paint will Mrs Smith need to buy for one coat of paint?
Solution: The wall has a total area of 7 x 3 = 21 m squared. In order to find the area to be painted, we need to subtract from this the area of the door and the window. The door has an area 2 x 1 = 2m squared, and the window has an area 2 x 1.5m = 3m squared. So the area to be painted is 21  2  3 = 16m squared. Each can of paint covers 4m squared so Mrs Smith will need 4 cans. 16 divided by 4 = 4 cans.
Remember to show your working out, and include your name and room number on your entry. Good luck.

Remember to include your working out, Name, and Room number on your entry and have it in the Mind Mover Competition Box before our Monday Morning Assembly. Good Luck
Solution: Using guess and check is a great way to use your prior knowledge and work from a realistic starting point. It is easier if you record your thinking in a table as it helps to organise your thoughts and track your equations.
Because 120 divided by 6 = 20 pizzas, a reasonable number to try for the first hour might be 20 plus a bit more. As a first number try 25 (as it is easier to count in 5’s)
1st hour 2nd hour 3 hour 4th hour 5th hour 6th hour total
Try 25 for first hour 25 20 15 10 5 0 75 (too few)
Try 30 for first hour 30 25 20 15 10 5 105 (too few)
Try 33 for first hour 33 28 23 18 13 8 123 (too many)
Try 32 for first hour 32 27 22 17 12 7 117 (too few)
Week 3/ Term 2
A signwriter has to paint the numbers 1 to 200 on a new set of private boxes. How many digits will the signwriter have to paint?
Solution: The most simple way to solve this is by separating numbers by their place value and then adding:
Numbers on the boxes Digits to paint
1  9 1 x 9 = 9
10  99 2 x 90 = 180
100  200 3 x 101 = 303
Total: 492
Week Two/ Term 2
If a box half full of apples weighs 18 kg, and the same box with ⅓ of apples weighs 14 kg, what does the box weigh when it is empty of apples?
Solution: The box plus half the apples weigh 18 kg, while the box plus a third of the apples weigh 14 kg. So by using subtraction, we eliminate the weight of the box and ½  ⅓ = 3/6  2/6 = ⅙ of the apples weigh 18kg  14 kg = 4 kg. Therefore, the total weight of the apples alone is 24 kg. So half the apples weigh 12 kg and the weight of the box is 18 kg so 18 kg  12 kg = 6 kg.
Week One/ Term Two
During the holidays, Reed went to the Gypsy Fair. At one of the stalls, nine cans are stacked on a bench in three piles of three as shown below.

Which three cans should you aim for and in what order should you try and topple them?
