Addition/Subtraction
 |
|

A plate divided into three sections can
be used to illustrate both addition and subtraction. For addition,
put manipulatives in both small sections (5+3). Move all of them
down to the larger bottom section to show the sum. For subtraction,
begin with all of the manipulatives in the large section and then
remove some to the smaller section to find out how many are left.

Use
candy to act out and record addition problems. |
|

The addition workmat is from Math Their
Way. |

Place stickers with numbers in the bottome of an egg carton. Place 2
small erasers in the carton and shake it up. Open and write and
addition problem about the tow numbers where the erasers fell. For
example, 2+4=6.

Sing songs or
read books to act out subtraction problems. Use teddy grahams and a
bed workmat while singing Roll Over to subtract one each time. The
children above were acting out Five Green and Speckled Frogs,
taking away one frog during each verse. |
|

He is using an animal plate and animal counters to solve the
addition problem 3 + 1. He put 3 counters in one paw and 1 counter
in the other paw. |
She did the same thing on this plate, but she first put the counters
in the animal's ears. Then she moved the counters down to the face
and counted them for the total.

Unifix Cube Sets

Record different combinations of unifix cubes to make sets of each
number. This recording sheet came from math Their Way.
|
Adding One More

We used this number line to practice adding one more to each number
by moving the frog one space each time. We learned that when you add
one to any number the answer is the next number you would count.
This pocket chart is a Lakeshore product.

Fly Swatter Addition
Write the
numbers from 0-10 on the chalkboard or on a shower curtain. Divide
class into teams and give each team a fly swatter. Call out an
addition problem and have the first team member “swat” the answer.
Continue playing, giving each team a point for correct answers.

Grab-Bag Mat
Give each
partner group a lunch bag with 10-12 unifix cubes in two colors (5-6
of each color). Have each child reach in and grab a handful of
cubes, pull them out, sort and count each color. Have them write the
number sentence. For instance if someone
pulled out 4 red and 4 blue cubes, they would write 4 + 4 = 8. Then
the next child takes his turn. I find it is helpful for
children to write everyone's equation as it gives them something to
do while waiting for their turn. You can do this as a small group
activity as well.

Addition War
Use number cards
that also have items to count corresponding to the number on the
card. Play it first like War for number recognition and comparing
sets. Then play it again by using two cards that they must add
together. It is like war: whoever has the highest number or
sum, wins all the cards. Person with the most cards wins the game.
