Let’s Practice for PSSA

• We are going to go over:• Shapes• Elapsed time• Solids• Making Change and Money review• Area with blocks• Perimeter• Line of Symmetry• Measurement Review

Shapes

• Hexagon –• Circle• Square• Rectangle• Triangle• Octagon

• Let’s draw some on your boards.

Center

Geometry

• Line Segment

• Angle

• Right Angle

• Vertex90

Degrees

Vertex

Time

• Write on your board – Like a digital clock.

• Another way of writing “fifty-five minutes after 8?”

Elapsed time

• You need to know

• How much time has passed

• What time something happened.

• Break the problem into parts.

• Do the hours first

• Count the minutes.

• A movie started at half past 3 It was 2 hours long. What time did the movie end?

• What time did it start?• 3:30• How long was it?• 3:30 + 2 hours more • 5:30

• A movie started at half past 3 It was 2 hours long. What time did the movie end?

• What time did it start?• 3:30• How long was it?• 3:30 + 2 hours more • 5:30

• Nilda has track practice from 3:30 to 5:15

• How long is practice?

• How much between 3:30 and 4:30?

• Can you count to 5:30?

• How much time between 4:30 and 5:15

• Count the minutes?

Let’s add some time

• Sue waited for 18 minutes for the train, then 43 minutes for the bus. How long did she wait for both the train and the bus?

• How would you solve this?

Solids

• Cube• Sphere• Cylinder• Cone• Rectangular Prism• Pyramid

Solids

• Faces –

• Corner

• Edge

Line of Symmetry

• A figure has symmetry if it can be separated or folded exactly in 2 parts.

Symmetry

• A figure that can be folded to make equal parts is a symmetrical figure.

Sometimes there are more than one line of symmetry

Money

Let’s add some coins:

Perimeter

• The distance around a figure

5 inches

6 Inches

Perimeter

Find the perimeter:

16 meters

10 meters

AREA

• The measure of space of a shape

• You have to count the blocks in all, like squares on the floor.

7 squares

6 squares

Find the Area

Volume• The measure of space in cubes – 3 D.

• You have to count the blocks that you can’t see.

Volume

• How many cubes?

Try again

• What is the number of cubes in all?

• Find the Volume – Count the cubes

Measurement

• US Customary –

• Length –inch, foot, yard and mile

• Weight – Ounce, pound and ton

• Capacity – teaspoon, tablespoon, cup, pint quart and gallon

Metric

• Length – Centimeter, meter and Kilometer

• Weight – Gram and Kilogram

• Capacity - Liter and milliliter

Open ended – What do you need?

• Ron has this much money?

• Does he have enough to pay for a meal that costs $2.29?

• What do you know about money to explain your answer?

• Ron uses his bills. How much change does Ron receive?

• Show your work?

• Explain how you got your answer?

We need POWER Math words

• First, Second…..

• To FIND OUT

• To SHOW

• To GET

• To solve
