3. What is the GIST Strategy • This strategy teaches us to use prediction as a comprehension aid when reading expository text. The ability to predict what a passage will be about is often based on prior knowledge. IT is broken down into 5 concepts: • Prereading – Predict the gist, or main point, of the text by scanning the page to get a feel for what it will be about. • Prompts – What do you think this text is going to be about? What makes you think so? What do you think it is going to tell us about our topic? What makes you think so? • Reading – read the assigned text. • Prompts – Did you find evidence to support your prediction? What was it? Did you find evidence that doesn’t support your prediction? What was it? At this point, do you want to change your prediction? Why or why not? • Postreading – Think about what you have read and make a final revision of the gist statement. • Prompts – Do you want to make any changes about this topic? If yes, what changes and why? What have you learned from this reading? Language Arts

5. Highest Common FactorLowest Common Multipleusing prime factor trees Find the HCF of 60 and 72 Find the LCM of 60 and 72 Find the HCF of 48 and 56 Find the LCM of 48 and 56

6. Make a Prime Factor Tree Find the HCF of two numbers Find the LCM of two numbers You will learn… how to

7. 2 8 10 Take two numbers What’s the biggest number that will go into both? 2 goes into 8 four times 8 ÷ 2 = 4 2 goes into 10 five times 10 ÷ 2 = 5 Highest Common Factor HCF There’s no bigger number than 2 that goes into both So it’s the biggest FACTOR or the Highest Common Factor

8. 40 8 10 Take two numbers If you do the times table for each at what number do they cross 1 2 3 4 5 6 7 8 8 16 24 32 40 48 56 64 10 20 30 40 50 60 70 80 Lowest Common Multiple LCM The first time they cross is at 40 So it’s the Lowest Common Multiple of these two numbers

9. Did you know? EVERY number is made from Prime numbers Multiplied together! Finding HCF and LCMusing the prime factor tree The first prime number is 2, then 3, then 5, then 7. It’s a number that no other number goes into except itself and one

10. Find the HCF of 60 and 72 Find the LCM of 60 and 72 Exercise

11. 60 Write 60 at the top of the page 30 2 60 = prime number 2 x 30 15 2 30 = prime number 2 x 15 3 5 15 = prime number 3 x prime number 5 Prime Factor Tree for 60 60 is all the prime numbers 2 x 2 x 3 x 5 multiplied together

12. 72 Write 72 at the top of the page 36 2 72 = prime number 2 x 36 18 2 36 = prime number 2 x 18 2 9 18 = prime number 2 x 9 Prime Factor Tree for 72 3 3 9 = prime number 3 x prime number 3 72 is the prime numbers 2 x 2 x 2 x 3 x 3 multiplied together

13. 60 72 3 2 2 30 36 2 2 x 15 18 2 2 3 5 2 9 x 3 3 12 Finding the Highest Common Factor Look for common factors in both trees Multiply them together = 12 is the biggest number that goes into both 60 and 72 So it is the Highest Common Factor

14. 72 60 36 2 30 2 18 2 2 15 3 2 9 5 3 3 Finding the Lowest Common Multiple 5 x 72 =360 2 x 3 x60 =360 Look for the factors remaining in either tree Cross multiply with top number in opposite tree 360 is the Lowest Common Multiple of 60 and 72

15. Find the HCF of 56 and 48 Find the LCM of 56 and 48 Exercise

16. 56 Write 56 at the top of the page 28 2 56 = prime number 2 x 28 14 2 28 = prime number 2 x 14 2 7 14 = prime number 2 x prime number 7 Prime Factor Tree for 56 56 is all the prime numbers 2 x 2 x 2 x 7 multiplied together

17. 48 Write 48 at the top of the page 24 2 48 = prime number 2 x 24 12 2 24 = prime number 2 x 12 2 6 12 = prime number 2 x 6 Prime Factor Tree for 48 2 3 6 = prime number 2 x prime number 3 48 is the prime numbers 2 x 2 x 2 x 2 x 3 multiplied together

18. 56 48 2 2 2 28 24 2 2 x 14 12 2 2 2 7 2 6 x 2 3 8 Finding the Highest Common Factor Look for common factors in both trees Multiply them together = 8 is the biggest number that goes into both 56 and 48 So it is the Highest Common Factor

19. 48 56 24 2 28 2 12 2 2 14 2 2 6 7 2 3 Finding the Lowest Common Multiple 7 x 48 =336 2 x 3 x56 =336 Look for the factors remaining in either tree Cross multiply with top number in opposite tree 336 is the Lowest Common Multiple of 56 and 48
