MATH

🚨 PART 1: THE #1 RULE

BEFORE USING ANY FORMULA:

1. What are they asking me to find?

2. What shape/object am I working with?

3. What words are clues?

4. What information did they give me?

5. Does my answer need units?

NEVER just grab a formula because you see a number.

Translate the WORDS → MATH

📐 PART 2: AREA

WHAT DOES AREA MEAN?

Area = the amount of space INSIDE a shape.

🚨 AREA CLUE WORDS

If you see:

cover

covering

inside

space inside

flooring

carpet

grass

garden

soil

paint

surface

square feet

square inches

square yards

square meters

👉 THINK AREA

🚶🏽 PART 3: PERIMETER

WHAT DOES PERIMETER MEAN?

Perimeter = distance AROUND the OUTSIDE of a shape.

Imagine walking around the outside edge.

🚨 PERIMETER CLUE WORDS

around

outside

border

fence

fencing

boundary

edging

outline

distance around a shape

👉 THINK PERIMETER

⭕ PART 4: CIRCUMFERENCE

WHAT DOES CIRCUMFERENCE MEAN?

Circumference = distance AROUND a CIRCLE.

Think:

Perimeter of a circle = circumference

🚨 CIRCUMFERENCE CLUES

around the circle

around the pond

around the fountain

around the pool

circular border

distance around

stones around

fence around a circular object

👉 CIRCUMFERENCE

📏 PART 5: RADIUS VS. DIAMETER

Radius

Half a diameter

Diameter

Half a circle

The diameter is twice the radius.

🧩 PART 6: COMPOSITE FIGURES

WHAT IS A COMPOSITE FIGURE?

A shape made from multiple smaller shapes.

It might look weird, like an:

L

T

step

irregular shape

🚨 CLUE:

If the shape can be broken into rectangles, triangles, etc.:

TO FIND AREA:

STEP 1: Break the figure into smaller shapes.

STEP 2: Find the area of each shape.

STEP 3: Add the areas together.

🧠 MEMORY:

COMPOSITE = BREAK IT APART

💰 PART 7: "PER" / RATES

The word PER is a BIG clue.

Examples:

dollars per hour

dollars per month

miles per hour

dollars per square foot

gallons per minute

"Per" usually tells you a rate.

BASIC RATE IDEA:

Example: Total = Rate x Amount

$1,500 per month for 4 months:

1500(4)= 6000

🚗 PART 9: DISTANCE/RATE/TIME

If your problems involve traveling, remember:

D = RT

d = distance

r = rate/speed

t = time

🚨 CLUES:

miles per hour → rate

how far traveled → distance

how long did it take → time

📊 PART 10: FUNCTIONS

You may see something like:

F(x)

or

D(t)

or

G(t)

IMPORTANT:

The thing inside the parentheses is the INPUT.

Example: (d)4

means: find the distance when t = 4

📋 FUNCTIONS WITH TABLES

Example:

Find 3 in the input row.

Then look underneath: 150

So: d(3) = 150

🧠 MEMORY:

INSIDE PARENTHESES = INPUT

TABLE INPUT → FIND IT → READ THE OUTPUT
