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

Using your fingers can also make subtraction
easy!
Hold up 4 fingers on your right hand. Now
put down two 2 fingers on your right hand
How many fingers are you holding up?
You are holding up 2 fingers. So, we just
learned that 4 - 2 = 2

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?
Questions?
Does anyone have any questions?
LET’S HAVE FUN WITH ADDITION AND SUBTRACTION!
