Number Sentences A number sentence is a short way of writing a mathematical expression. EXAMPLE I could write: eight plus six equals fourteen or I could write it this way: = 14 Copyright © 2010 Kelly Mott

14
**A number sentence can be TRUE. EXAMPLE 5 x 2 = 10 **

Number Sentences A number sentence can be TRUE. EXAMPLE 5 x 2 = 10 Copyright © 2010 Kelly Mott

15
**A number sentence can be FALSE. EXAMPLE 6 - 2 = 6 **

Number Sentences A number sentence can be FALSE. EXAMPLE = 6 Copyright © 2010 Kelly Mott

16
**25 + 3 = 29 Circle: True or False**

Is it TRUE or FALSE? = 29 Circle: True or False > 51 Circle: True or False Copyright © 2010 Kelly Mott

17
**Some number sentences use PARENTHESES. EXAMPLE (6 – 2) + 4 = 8 **

Copyright © 2010 Kelly Mott

18
**To solve these, you must do what’s in the PARENTHESES first.**

Number Sentences To solve these, you must do what’s in the PARENTHESES first. (6 – 2) + 4 = 8 Copyright © 2010 Kelly Mott

19
**Number Sentences (16 - 6) x 2 = ______________**

Copyright © 2010 Kelly Mott

20
**C. (8 + 2) x 5 = ______________**

Number Sentences C. (8 + 2) x 5 = ______________ D (2 x 5) = ______________ Copyright © 2010 Kelly Mott

21
**Sometimes you have to tell if a number sentence is TRUE or FALSE.**

Number Sentences Sometimes you have to tell if a number sentence is TRUE or FALSE. Copyright © 2010 Kelly Mott

22
**Number Sentences (2 x 5) + 10 = 25 True or False**

B = 4 + (3 x 2) True or False Copyright © 2010 Kelly Mott

23
Number Sentences Sometimes you have to add PARENTHESES to make a number sentence true. EXAMPLE x 4 = 8 Copyright © 2010 Kelly Mott

24
**16 - 2 x 4 = 8 MAKE THE SENTENCE TRUE CHECK LIST:**

___ Circle the relationship symbol (= < >) ___ Start with the side that has numbers and operations. ___ Try parentheses around the first set of numbers and operation. ___ Do the math. ___ See if it’s true. ___ If not true, put parentheses around the next set of numbers and try again. Copyright © 2010 Kelly Mott

25
**5 x 7 - 5 = 30 MAKE THE SENTENCE TRUE CHECK LIST:**

___ Circle the relationship symbol (= < >) ___ Start with the side that has numbers and operations. ___ Try parentheses around the first set of numbers and operation. ___ Do the math. ___ See if it’s true. ___ If not true, put parentheses around the next set of numbers and try again. Copyright © 2010 Kelly Mott

26
**8 x 2 + 1 = 24 MAKE THE SENTENCE TRUE CHECK LIST:**

___ Circle the relationship symbol (= < >) ___ Start with the side that has numbers and operations. ___ Try parentheses around the first set of numbers and operation. ___ Do the math. ___ See if it’s true. ___ If not true, put parentheses around the next set of numbers and try again. Copyright © 2010 Kelly Mott

27
**12 ÷ 4 x 3 = 9 MAKE THE SENTENCE TRUE CHECK LIST:**

___ Circle the relationship symbol (= < >) ___ Start with the side that has numbers and operations. ___ Try parentheses around the first set of numbers and operation. ___ Do the math. ___ See if it’s true. ___ If not true, put parentheses around the next set of numbers and try again.

**A number sentence is open if it has a VARIABLE. EXAMPLE 12 + x = 15 **

Number Sentences A number sentence is open if it has a VARIABLE. EXAMPLE 12 + x = 15 Copyright © 2010 Kelly Mott

30
