Transformations

Translation- slide along a straight line
Rotation- turn about a fixed point
Reflection- mirror image

Know how to do and describe each of them
plot (-4, 6) on this grid. Sorry if the grid is too small.

(sorry i don't know how to put roman numerals sign)

(+,+) = Quadrant 1

(-,-)= Quadrant 3

(-,+)= Quadrant 2

(+,-)= Quandrant 4

Notes for May 25,2011

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
