WRITING EXPRESSIONS

Write the expression just like it is read. The only exception is Phrases with ‘than’ in which the numbers are reversed. LESSON 3.2 RECALL Write the expression just like it is read. The only exception is Phrases with ‘than’ in which the numbers are reversed.
3
LESSON 3.2 RECALL First choose the order of the numbers Phrases with ‘than’ the numbers are reversed Phrases with ‘by’ the numbers are in right order Phrases with ‘and’ the numbers are in right order

LESSON 3.2 RECALL First choose the order of the numbers Phrases with ‘than’ the numbers are reversed Phrases with ‘by’ the numbers are in right order Phrases with ‘and’ the numbers are in right order Second choose the operation + – x ÷ more than less thanTwice as manyQuotient of greater than fewer thanTimesDivided by increased by decreased byProduct ofDivisible by The sum ofdifference of

LESSON 3.2 RECALL 6 more than a number first write n then 6next add the sign n + 6 10 decreased by 8 first write 10 then 8next add the sign10 - 8 The product of 5 and 10 first write 5 then 10next add the sign 5 x 10 The quotient of 6 and 2 first write 6 then 2next add the sign 6 ÷ 2

LESSON 3.2 RECALL 6 more than a number first write n then nnext add the sign n + 6 10 decreased by 8 first write 10 then 8next add the sign10 - 8 The product of 5 and 10 first write 5 then 10next add the sign 5 x 10 The quotient of 6 and 2 first write 6 then 2next add the sign 6 ÷ 2

LESSON 3.2 APPLY How would you write 6 times a number greater than 8?
13
LESSON 3.2 APPLY reverse How would you write 6 times a number greater than 8? First write 8 then 6nnext add the sign 8 + 6n
17
LESSON 3.2 ANALYZE Which expression is correct? The product of two and 6 times a number 2 + 6n The sum of three and five decreased by 7 5 + 3 + 7 8 more than a number minus 5 n + 8 - 5
18
LESSON 3.2 ANALYZE Which expression is correct? The product of two and 6 times a number 2 + 6n The NO! the correct expression is 2 x 6n 8 more than a number minus 5 n + 8 - 5
19
LESSON 3.2 ANALYZE Which expression is correct? The sum of three and five decreased by seven 5 - 3 + 7
20
LESSON 3.2 ANALYZE Which expression is correct? The sum of three and five decreased by seven 5 - 3 + 7 NO! The correct expression is 3 + 5 - 7
21
LESSON 3.2 ANALYZE Which expression is correct? 8 more than a number minus 5 n + 8 – 5
22
LESSON 3.2 ANALYZE Which expression is correct? 8 more than a number minus 5 n + 8 – 5 YES! n + 8 - 5
23
LESSON 3.2 EVALUATE If 3 represents a number, what would be the outcome for 4 times a number less than 20?2 5 = 2 x 2 x 2 x 2 x 2 = 32
24
LESSON 3.2 EVALUATE If 3 represents a number, what would be the outcome for 4 times a number less than 20? 20 – 4n 20 – 4(3) 20 – 12 = 32 8
28
LESSON 3.2 CREATE Create an expression using the words decreased by where the outcome is equal to 32
29
LESSON 3.2 CREATE Create an expression using the words decreased by and one other phrase where the outcome is equal to 32 Possible solutions might be: 34 decreased by 5 plus 3 The product of 3 and |15| decreased by 13 6 squared decreased by 10 plus 6
30
LESSON 3.2 CREATE Create an expression using the words decreased by and one other phrase where the outcome is equal to 32 Possible solutions might be: 34 decreased by 5 plus 3 The product of 3 and |-15| decreased by 13 6 squared decreased by 10 plus 6
31
LESSON 3.2 CREATE Create an expression using the words decreased by and one other phrase where the outcome is equal to 32 Possible solutions might be: 34 decreased by 5 plus 3 The product of 3 and | –15| decreased by 13 6 squared decreased by 10 plus 6
