IT "ADDS UP" OUTDOORS

The sun is shining so let’s take state standards out on the playground for some counting and cardinality.

Number Hunt
Take lunch sacks and write different numerals on them. Give each child a bag and ask them to make that set and put it in the bag. Let children share what they have found with their friends. Have children return the objects to where they found them.

*This can also be done with a partner or in small groups.

Hint! Whenever collecting things outside remind the children to only pick up items off the ground. You never want to pull leaves or flowers off plants because it might hurt them.


Counting
Children can count trees, fence posts, balls, bushes, and many other items on the playground.
*Have children estimate how many and then verify their guess by counting.




Exercise and Count
Have children count how many times they can jump rope. How many jumping jacks can they do? How many times can they bounce and catch a ball without dropping it?


Dot to Dot
Take chalk and write numerals 0-20 randomly on a hard play surface. Children start with zero and run, hop, march, or skip to each numeral in order.

*Adapt the amount to the ability of your students.



Estimation
Fill a basket with rocks, pinecones, leaves, or other natural objects. Ask the children to estimate how many there are. Count the objects. Who guessed more? Who guessed less? Who was closest?

Patterns

Collect 5 or 6 leaves, rocks, sticks or other natural objects. Place a leaf, then a rock, a leaf, then a rock. “What will come next?” Let children make up their own patterns with objects in nature.

Addition & Subtraction

Work out addition and subtraction problems with sticks, leaves, and other natural objects.

Geometry
Draw basic geometric shapes (square, triangle, rectangle, oval, rhombus, circle) on 6” cardboard squares. Pass out the shapes and challenge the children can find something on the playground with a similar shape.

*Divide children into small groups and let them make shapes with their bodies on the grass.

Measurement
Give children rulers to measure objects on the playground. “Can you find something 2” long? Can you find something smaller than an inch? What’s longer than 5”? How can you measure the slide?”

*Give children a popsicle stick or piece of string and ask them to find something longer, shorter, the same size, etc.



Position I Spy!
Children use positional words to play “I Spy” on the playground. For example: I spy something beside the slide. I spy something behind the tree. I spy something above the sidewalk. I spy something between the big tree and the fence…

Sorting
Ask children to collect different items on the playground. (This will vary with the season and your habitat.) Put their objects together in a big pile. Ask the children to sort the objects. What was their sorting rule?

Seriation
Collect sticks of different lengths and have the children put them in order from smallest to largest.
*They could also seriate leaves, rocks, etc.

Graphing
Ask each child to find a leaf on the playground. Make a graph and have the children lay their leaf in the appropriate space. Compare quantities.

BATS AND SPIDERS - OH, MY!

You can take any seasonal objects like erasers, small toys, or natural items (leaves) and turn them into learning materials. Here are some ways to use bat rings and spider rings this month for hands-on math.


Note! I took my scissors and snipped off the ring part to make them easier to manipulate. I also removed the skeleton rings because I thought some parents might object. (I just try to keep everybody happy!)

Sort
Ask children to sort the rings. What was their sorting rule? Can they sort them another way?



Sets
Draw spider webs and label with numerals or number words. Children make appropriate sets.

*Use bat rings in spooky trees. Let children roll dice and make the amount.

Guess and Check

Put different amounts of rings in bags or cups. Write letters on the cups (A, B, C...). Children count and then record their answers.



Addition and Subtraction
Children can work out math problems with the spider rings.



Fill the Cup (I learned this from Carolyn Kisloski.)
Two or more children can play this game. You’ll need cups, plastic toys, and dice. Children take turns rolling a die and then counting out that many objects and placing them in their cup. The first one to fill their cup is the winner. To extend the game, continue playing to see who can empty their cup first.

*Use two dice so the children can practice addition.


Estimate
Fill a plastic jar with plastic toys. Children estimate how many and then write it on a sheet of paper with their name. At the end of the day count the objects. Who guessed more? Less? Who was closest?


Patterns
Can children continue a pattern with the toy rings? Can they create an AB, or ABB pattern?



Position
Give each child a spider ring. Can you put it above your head? Can you put it beside you? Can you put it between your knees? Etc.


Bats in a Cave
Make a cave from a disposable bowl by turning it upside down and cutting an arch as shown. Display a certain number of bats. Put some in the cave and ask children, "How many do you see? How many do you think are in the cave?"

Patterns
Use the pompoms for making patterns.


Estimating
Have children estimate the number of each type and then verify by counting.


Math Mat
Children place the correct amount on the trees.



Match Dot Cards
Pompoms are a perfect one-to-one activity for younger children.



Touch and Tell
Place numbers in a bag. Children reach in, feel a number and try to identify what it is. They can take it out to confirm and then write the number.


Number Hunt
Put numbers in a box of Styrofoam packing or sand. Children search through the Styrofoam packing and color off the numbers as they find them.


Stampers
Stamp a pattern, stamp out math facts, or stamp a set.




Roll of the Dice
Roll them, count them, add them, or let children make up their own games with the dice.

PARTY TIME

Need some ideas for your holiday party? These games are easy to adapt for any event. For example, instead of playing pin the red nose on Rudolph you could play pin the carrot on Frosty's nose. Rather than using sweet treats you could use pencils, stickers, or another prize.

Hint! Parents who are in charge of your party might appreciate these suggestions.

Pass the Parcel
This is actually a game a student from England taught me. Thus, “parcel” instead of “present.” My students LOVED this! Fill a box with sugarless bubblegum, pencils, small toys, or stickers. There should be enough for everyone in the group. Next, wrap the present over and over again with wrapping paper, tissue paper, or funny pages from the newspaper. Children sit in a circle and begin passing the “parcel” around as music is played. When the music stops that child gets to open one layer on the package. (If the package lands on someone who has already had a turn they pass it on to the person sitting next to them.) Continue the game until the gift is reached. That child then passes out the goodies to the rest of the group.


Hide and Hunt
Children love to hunt for things, so if the weather is nice you can hide jingle bells, snowballs (cotton balls), chocolate gold coins, small toys, etc. on the playground for the children to find. (If the weather is lousy, move it indoors. The kids won't care!)


*Divide the class in half. Let one group hide the objects for the others to find and then reverse roles.

Crackers
These won’t really crack, but they are lots of fun to make or give to friends. They can also add a special touch to a special holiday table.

You will need: cardboard rollers, wrapping paper, candy, small toys, curling ribbon
Cut the cardboard rollers into 5” sections. Fill with candy and little toys. Roll in wrapping paper, twist the ends, and tie with curling ribbon.

*This would be a nice gift to make for a nursing home or shelter. 



Magic Number
Fill a clear jar or container with candy, cotton balls, or jingle bells. The person who guesses the closest amount is the winner.



Pin the Nose on Rudolph
Draw a reindeer on a poster or chalk board. Cut out red circles and have each child write her name on a circle. Put tape on the back of each circle. One at a time, blindfold each child and spin them around gently three times. Face them towards the reindeer and challenge them to put the nose on Rudolph. Who can get the closest?

Puzzle Pairs
Take old greeting cards and cut them in half like a puzzle. Give each child one half. Have them close their eyes while the other half is hidden in the room. Children tiptoe around the room until they find their matching puzzle piece and sit down.

Pantomime and Name That Tune
Children love to perform, so they always enjoy playing “Guess who I am?” with seasonal objects or toys. They can also take turns humming seasonal songs for their friends to identify.

Word Games
Write a seasonal word on the board. How many words can they create using the letters in the seasonal word?
Hint! Pair children for this activity to enable all children to feel successful.

Holiday Four Corners
You will need four seasonal pictures to tape in each corner of the classroom. For example, a snowman, bell, candy cane, and candle. One child is “it.” “It” hides her eyes and counts to ten as the rest of the class tiptoes to a corner. “It” then calls out one of the objects. The students in that corner are out and must sit in the “stew pot” (center of the room). “It” counts to ten again as the students tiptoe to a new corner. The game continues until one child is left. That child becomes the new “it.”
