Use this method to work out 30 x 235.

(30 x 200, 30 x 30 and 30 x 5, then put together)

Share 369 candies among 3 friends using similar strategies of partitioning.

3(00) / 3 = 1(00)

6(0) / 3 = 2(0)

9 / 3 = 3

so 100 and 20 and 3 is 123.

Lesson 3:

State Standard: 5A1

The car carrying truck has 12 wheels. It has to pay a toll of $5.00 for every wheel including the trucks and the cars it is carrying. How much toll might it need to pay? (Share solutions in the form of a table I.e., )

State Standards Practice:(25 min.)

What would the Toll be for carrying 10 cars? (12 + 40)= $52

If it could carry 100 cars, what would the toll be? (12 + 400) = $412

In the problem above , which part is always the same?

(The truck wheels, 12)

Which part changes?

(The car wheels)

We can write an Algebraic Expression for this problem:

The Toll is the number of Truck wheels plus the number of Car wheels

OR

T = 12 + C

In this problem 12 is a CONSTANT as it never changes,

while C is a VARIABLE as it changes.

T is the answer.
