  1. 1. Can you work Systematically?
  2. 2. Problem solving <ul><li>In maths this week we have been trying to solve problems SYSTEMATICALLY . </li></ul><ul><li>Being systematic means that you solve a problem in an organised way. You think about how you will set out your work and make sure you have tried ALL of the possibilities. Have a look at how we got on… </li></ul>
  3. 4. <ul><li>We had 4 counters </li></ul><ul><li>We had a cup and a hoop </li></ul><ul><li>You got 10 points if a counter was in the cup </li></ul><ul><li>You got 5 points if a counter was in the hoop </li></ul><ul><li>You got no points if a counter was outside the hoop </li></ul>
  4. 6. The problem <ul><li>We had to find out ALL of the different ways you could score point: </li></ul><ul><li>So scores: </li></ul><ul><li>10+10+10+10=40 </li></ul><ul><li>Get it? </li></ul>
  5. 8. This is how Ahmad and Maliha got on (it got a bit rubbed out on the carpet!
  6. 10. In the end we tried to work out all the possibilities on the carpet <ul><li>IN A SYSTEMATIC WAY! </li></ul>10+10+10+10=40 10+10+10+5=35 10+10+10+0=30 10+10+5+0=25 10+10+0+0=20 10+5+0+0=15 10+0+0+0=10 5+0+0+0=5 0+0+0+0=0 5+5+5+5=20 5+10+5+5=25 5+10+10+5=30 5+5+5+0=15 5+5+0+0=10 5+5+10+0=20
  7. 12. How did we get on? <ul><li>Did we find every possible way to do it? </li></ul><ul><li>Could we have set it out better? </li></ul><ul><li>Could you improve on our work? </li></ul><ul><li>Tell us what you think in a comment </li></ul><ul><li>How many ways could you score with 5 counters instead of 4? </li></ul>
