Estimation Station.......... One of the easiest ways to do this is to have a weekly estimation jar. Every week you could change the contents of the jar or the size of the jar. Sometimes put large objects and sometimes small. Let children examine the jar and write their estimations. You can go further by having them write a paragraph about "how" they got their guess. At the end of the week count the objects together or have the last center count them. Teach them some estimating skills. Also at the estimation stationyou can have them estimate the capacity of a container.Have a container and the material (clothespins). Have then make a prediction of how many and then actually fill the jar to check their predictions. Small manipulatives could be used for this and you could change the size of the container weekly.

I have an estimation and Venn diagram centre which is changed every day. I found one week was too long, and if you do a "theme" for the estimation it can last 5 days (e.g estimating the plastic small teddy bears... changes the size of container over 5 days). You can also ask questions like :"Yesterday the jar was full of plastic teddy bears. Today it is half full of teddy bears. How many teddy bears are in the half full jar?" I always write the questions this way like word problems. They write their estimate on a sheet, circle it and write their names next to it. The child with the closest estimate wins a prize. We always count the objects together and I use this as an opportunity of demonstrating division, multiplication etc. Some days I even ask them to write their estimations in their math notebooks and explain how they got their answer using words, numbers and pictures.

The Venn Diagrams can also be changed every day and then when you've got enough of them they can be placed at a Graphing centre and children can each choose one Venn diagram to graph on their own. Venn Diagrams can also be made into a book and sent home each night with a different child. Most parents haven't a clue what a Venn diagram is. You can have a couple of incomplete venn's for parents to sign at the back of the book. Venn Diagram results can also be reported in the class newsletter. Michael in Toronto
P.S. Strongly recommend new primary teachers try this starting the first day. Just set the centre up at a small table. You can cover a lot without having to do a lot of preparation or direct teaching.

Venn Diagrams - any easy way to make a versatile and portable Venn Diagram is to use air hose tubes from aquariums. The tubes are really cheap and you can buy connectors for them as cheaply. Make two circles using the tubes and you can overlap the circles and place the items in the appropriate place. These can be labeled with 3x5 cards. You can also have a group make a Venn diagram ( 2nd grade) and leave off the labels. Have other students look at the diagram and try to guess how it has been sorted. (c/o Djinn)

I do a Venn diagram almost everyday as a warm-up when they come in. I have their names laminated with a magnet on the back and place on their lockers. I use the cute patterns you see on note pads that go with my class theme (ocean life, teddy bears, hockey pucks...)
I write a question of the day on the board and they put their name either inside or outside the circle (yes/no) to answer the question.This is a spring board for many math ideas and comparisons. My circle is a hoola hoop that I place on a shower hook and magnet man on my magnetic chalkboard (lucky me!)As the year goes on I add another hoola hoop for the Venn diagram. I was asked to get to three circles this year for first grade, but it wasn't happening. I have friends who say it works great with
2-5...it just confused the kids and me. No math major here. tee

Found this in an old book:
Cut an egg carton in half:
Open it, on the side that is the top write a problem like
25
+46
On the side where the eggs would be, students use chips to represent each number...So 2 chips in on egg section, 5 chips in the egg section next to it
then underneath, 4 chips, then 6 chips.
Students use chips in the sections to solve problem
Tell them the rule, if you have ten you trade...
You could also , on the egg section write a + sign and draw a line to represent where the answer goes...
Hope this makes sense! (c/o Abby)

Math Their Way Tubs are very appropriate.

Another center could be patterning. There are many activities that could be done with pattern blocks. Another source for centers is Box It or Bag It. Amy

You could have a math literacy center that include literature and laminated activity cards. I'm thinking mostly of Marilyn Burns literature collections, there's k-3 and 4-6.
the Family Math book also might have some ideas that would be good centers.

Another great resource for math center ideas for K-1 is the Math In My World book put out, I think, by Creative Teaching Press. It is divided into 5 sections: All About Me, Nature, Playground, Food & Nutrition, and
something else, it might be Families. It also includes ideas on how to involve parents in each theme. JuliAnne

Since I teach first grade my all my centers would not be
applicable, but the following might help and could be
1. Beat the calculator(credit to Chicago Math)
Materials: deck of math facts to be studied, calculator
Students work in pairs, one student uses the calculator, theother student uses their brain--turn over a card with math fact--the first to give the correct answer keeps the card--the winner is the student with the most cards--second gamereverse roles.
2. Problem solving: a problem is posed/could be written on
note cards/or posted--children solve problem and using largedrawing paper illustrate how the solved the
problem--procedure can be shared
3. multiplication (or in my case addition and subtraction)
bingo--make your own cards or purchase game
4. Teacher Created Materials has a set of resources called
Science in a Bag, Math in a Bag etc. These were written withthe intention of being homework/bring back to school and use--ideas, they can be adapted to the classroom and become centertype activities--I have not done this yet--one of my goalsfor this year
5. tangram puzzles
6. tessellation's

Here is a center that my students enjoyed. I bought some wooden dowels. I had someone cut them in different lengths. I labeled each one A,B,C,..etc.The task was estimating. The students picked a dowel,estimated how long it was,measured it then looked at the letter and used the answer key to check their answer.The measurement used was inches.Another center is graphing.When we did it as a class,we used m&m,skittles or some other edibles.In the center, you can use different color buttons,different kinds of beans or different shape pasta.The students pick a container ,group the items then use graph paper to draw a graph to represent the items.What I like about this center is that it can accomodate several students at the same time all drawing each their own graphs in their group.Of course some students prefer working on their own graph. The drawing can be checked in a second and problems noted for small group reteaching later.
Hope someone can use these ideas.

One other activity that I use is to make measurement boxes. I put several things in a shoe box. The student measure the objects and records the answer. I have the answers in the lid of the box. I show the students how to open the box, put the lid under the box and then measure. Another idea is to find petri dishes (the kind that the science teacher at the high school might have) that are divided into two sections. I have students put in beans of the number that we are working on and shake the dish and then write the equation. For example if we are working on 9, they would put in nine beans, shake and record 5+4=9, because there will be 4 beans on one side and 5 on the other, shake and record again. These dishes are great because they can be put on the overhead. Amy

I just thought of another idea that I do. When I introduce "doubles", I have cloth bags with the following objects: a car, plastic insect, plastic spider, a picture of a hand, an egg carton, a calendar page, a box of 16 crayons, and a picture of a semi truck. Students reach into the bag and record a double, for example if they pick a car, they record 2+2=4, because there are 2 wheels on each side. The insect is 3+3 because of the legs etc. They love to work with the bags and will record answers over and over. Am

There is a new Math program out called Quest 2000. It has
excellent ideas and they refer to their math centers as tubbing. They start with a whole class lesson and then reinforce math skills through 6 to 8 tubs. The ideas are amazing and the students love to get into the tubs. Mel

Other Math Centers (posted by Mona 1998)

Math Games---Commercial games such as Yahtzee, dominoes, chess, and bingo develop math and logic skills.

Money Activities: Children can sort, identify and graph coins. They can count by ones (pennies), fives (nickels), and tens (dimes). A set of money stamps is great for recording work. Using the stamp students can create money rebus stories.

Dollar Activities-There are 293 ways to change a dollar bill. Let the students use the money stamps to stamp out the different ways on butcher paper.

Set up a toy store or mini grocery store.

Graph of the day is a great center to have at a math center. Examples are:
Favorite Subjects
Favorite Sports
Pets You Have
Let the children decide on some graphs.

Fractions-- Have manipulatives to explore fractions as equal parts of a whole. Provide paper shapes and graph paper to fold and cut. Have things like coins, buttons, crayons, counters for finding equal parts of a set.

Measurement-Have students use measuring cups to measure rice to fill containers ½, ¼, 1/3 full. Measuring spoons can also be used to explore equal measures.

Math in a Bag-Lunch bags can be used to put different math activities in. These are especially useful if you have games with many pieces. Students pour out the activity and then place it back in the bag when complete.

Math Geo Safari-- Expense here, but can be used for individualizing skills and fast practice.

Manipulatives for Math Center:

This is just a take off of the red/white lima beans from Math Their Way--instead of painting the lima beans red on one side, I spray painted them sunburst yellow (both sides, but you could leave one side white) then I drew smiling faces (just eyes and mouth) on one side with a black sharpie marker. It's hard to look at over 300 smiley faces and not smile. I will use them for patterning, making equations, seeing how many times you have to roll a dice before you get to pick 30 smiling faces, keeping track of rolls with tally marks. Basically whatever you use a two sided counter for. I guess it's time to start school, I'm starting to have too much time on my hands.

Another idea like this that I just recently read on this site
is to spray lima beans is to….. 1. Spray one side of the beans
orange and draw jack-o-lantern faces on them for the fall.
and 2. Either spray on side white (or leave unsprayed) and
draw ghost eyes on a vertically held bean.

I did this years ago and the beans hold up great. I sprayed both sides orange and a mother put the faces on one side. So we had pumpkins and jack o' lanterns. Then she took plain beans and put ghost faces on one side.

I have glued two beans, one on top of the other, and sprayed them green, then glued little wiggly eyes on them. They make cute counters and last for years. Nancy

If you have math centers to share please consider posting them to this board. Teachers are always on the LOOK for new center ideas!! If you use centers in your classroom you may want to also check out Lori V's literacy centers ,
Science Centers by LuAnn and the lesson called Discovery Bottles!
