### MATH SIGNS

A math specialist one told me how important it was to have the children look at the signs when they are doing math. Most children know how to work the problems, but they often forget to look at the sign first. Here’s a little rap to make it more fun.

Stop, look, and think,
Before you add or subtract.
Pay attention to the signs
When you do your math!

Plus sign, plus sign,
What do you say?
Put them together.
Join sets, I say!

Minus sign, minus sign,
What do you say?
Subtract a set.
Take it away!

Equal sign, equal sign,
What is your game?
The amount on either side
Is always the same.

Look at the signs before you begin,
And your answer will always win!

Hint! Here is a tool that can help children solve word problems. Fold a sheet of paper into fourths. Open and fold in half. Cut half way up one creased line as shown. Make a “+” on the right and a “-“ on the left. Lift flaps and write key words for adding and subtracting. For example:

Addition: plus, in all, altogether, how many, sum
Subtraction: less, minus, left, take away, fewer, difference

Money Musical Chairs
Place chairs in a circle and put a coin on each chair. Play some music for the children to march around. When the music stops they have to identify the coin by where they are standing.

*Make the game more difficult by putting several coins for the children to count.

Skip Counting
Skip counting is one of those "prior learning" activities that we can do with young children.  When they get older and have to learn multiplication facts it will be a "song."

Sing and skip count by 2’s to “Twinkle Little Star.”
Practice counting by 3’s to “Are You Sleeping?”
4’s “Row Your Boat”
5’s “The Bear Went over the Mountain”
6’s “London Bridge”
7’s “Ten Little Indians”
8’s “This Old Man”

Hi Ho Adding We’ll Go
(Tune: “The Farmer in the Dell”)
1 plus 1 equals 2 (Hold up fingers as you sing.)
1 plus 1 equals 2
Hi, ho, adding we’ll go. (Roll hands around.)
1 plus 1 equals 2

*Continue singing with other math facts.

Doubles Don’t Give Me Trouble (Sarah Jackson)
(Tune: “I’ve Been Working on the Railroad”)
1 + 1= 2, 2 + 2 = 4, 3 + 3 = 6, 4 + 4 = 8, 5 + 5 = 10, 6 + 6 = 12
Now I know my doubles,
They don’t give me any trouble!
7 + 7 =14, 8 + 8 = 16, 9 + 9 = 18, 10 + 10 = 20, 11 + 11 = 22, 12 + 12 = 24
