Writing Expressions

After a review of last night's homework assignment, we practiced the skills of PEMDAS and critical reading to write number expressions (not inequalities). Some practice items included:
a plus 7 (a + 7)
x decreased by 4 (x - 4)
5 less than s (s - 5)
The product of 8 and c (8c)

Then students, with partners, played a "Bingo" game with given word expressions and matched them with the correct number expressions. Here is a sample of some examples that students worked on:


The product of 5 and t                                                                       

The product of 8, m,and n

The product of 3 and the quantity of  p plus q                                    

Twice the sum of  x and y

The product of m and 3 less than m                                      

x  divided by 5

Homework for tonight: read over notes 1/7, 1/8, 1/12, and 1/13.
