c= cup
c + 3
Let say there are 6 counters in the cup
6 + 3
6 + 3= 9
^^^ That is an equation...
3c + 2
3(4) + 2
3 x 4 = 12
12+2= 14*
* over all marbles
________
Now try to answer this:
4 x + 3
x= 3
Answer:
Table of Values- a table showing two sets of related numbers
Table:
how many squares in figure # 60?
Answer is 60= 121
x2+1 is the expression
2(60)+1=121
2f+1= s
^^f= figure
model the expression
2y + 4 with cups and counters
then show if:
y= 1
y= 3
y=1
2y + 4=
2(1) + 4=
2+4=
6=6
y= 3
2y + 4=
2(3)+4=
6+4=
10=10
