- 1. Mind Mover #1There are 9 apples and 4 bags. How can you put an odd number of apples in each of the bags?Title: Mind Mover #1Ideas: How did you try to solve it?Answer: What is your final answer?
- 2. Mind Mover #1 SolutionTough one on the first day…Because 0 is an even number it can’t be used.If you sum 4 odd digits (any combination of 1, 3, 5, 7) they always give you an even number.So you have to get creative…I heard some good solutions…bag inside bag, eating an apple, removing a bag, etc.There is no one correct answer but there is definitely lots of ways to try!
- 3. Mind Mover #2What 3 numbers are represented the by the 3 letters in this subtraction problem?TitleHow did you solve the problem?What were the values of the letters?A B A- C A A B
- 4. Mind Movers #2 SolutionA B A- C A A BI know that B has to be zero…because any number subtracting itself is zero!So then start guessing and checking with three digit numbers ex: 101, 202, etc.Fill in what you know.Get C to workA=1 B= 0 and C=9A 0 A- C A A 0
- 5. Mind Mover #3A ball is dropped from a ladder 8 m high. It bounced up ½ the distance it fell each time. It bounced until it as it bounced UP to a height of 1 m. How many times had the ball bounced?Title Draw a diagram(s) to represent the question.Solution
- 6. Mind Mover #3 SolutionBy drawing a picture you can clearly identify what half the height looks like for every bounce.It would take three bounces for the ball to be caught at a height of one metre.8 m4m4m2m2m1mBounce #1Bounce #3Bounce #2
- 7. Mind Mover #4We are building a fence that requires fence posts every meter. If you need to fence in a yard that is 3m by 5m; how many fence posts will you need?TitleHow did you start this problem?Did your thinking change in order to find a solution?Solution
- 8. Mind Mover #4 Solution3mYou might think this is a super easy problem. 5m sides needs 5 posts and 3m sides each need three postsAnyone see a problem here?We need posts on every corner for a fence!5mIn total we need 16 posts in total!
- 9. Mind Mover #5If it takes 4 students 3 minutes to put up 3 badminton nets, how long will it take for 6 students to put up 3 badminton nets?TitleCan you identify a pattern? Did the pattern help you solve the question? If not how did you solve the question?What is the solution?
- 10. Mind Mover #5 SolutionIt takes 4 students 1 minute per net.So it would take 8 students 30 seconds per netIf I follow the pattern 4 = 608 = 30 6 is half way between 4 and 8, so 45 seconds is between 60 and 30.Therefore it would take 6 students 45seconds per net; and if there are 3 nets (3x45) is 135 seconds (2 minutes 15 seconds).
- 11. Mind Mover #6Add, subtract, multiply or divide all the digits 1, 2, 3, 4, 5 to reach an answer of 10.TitleHow did you solve the problem?Make sure you remember BEDMAS when doing your calculations.Show your full solution!
- 12. Mind Mover #6 SolutionGuess and check would be the most common method to solve this problem.There are many solution here is just one!
