Lesson IntroductionAddition and Subtraction made fun!

Addition is adding things together

We show addition by using a plus sign

This is a plus sign:

When we show the answer in math, we use an equal sign

This is an equal sign:

Equals means “what you get” after you add things

together

The Science of AdditionThe signs

Using your fingers can make addition easy!

Hold up 2 fingers on your right hand.. Now

hold up 2 fingers on your left hand

How many fingers are you holding up?

You are holding up 4 fingers. So, we just

learned that 2 + 2 = 4

Fun with Flashcards

• To make our flashcard we will need:• Construction paper• Glue• Cotton balls• Beans• Candy• Math worksheet• Markers

Math Worksheet 5 – 3 = 6 – 4 = 2 + 1 = 3 + 2 = 4 – 2 = 3 + 4 = 7 + 3 = 9 – 5 = 6 + 3 = 8 – 5 =

Example

Flashcard Example Using Addition

• 3 + 2 = ?

•What will our flashcard look like?
