MATH FUN IN THE SUN

The sun is shining so let’s take 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.

YOU'RE INVITED TO A SUPER BOWL PARTY

FEBRUARY 11, 2024

Get ready for the game next weekend with these learning activities.




Survey Says
Let children do surveys (classroom, at home, etc.) to find out which team others think will win the Super Bowl.

Vocabulary
“Offensive,” “Defensive,” “Penalty,” “Referee,” “Substitution,” “Huddle” …How many football terms can you think of that might be meaningful to learn?

Jersey Math
Let children choose their favorite player’s number and write it on a paper jersey. How many facts can they think of that equal that number.

Starting Line Up
At the beginning of the day let children make two lines facing each other. Introduce one child at a time and let them run through the two lines as their friends give them high five and cheer.

Good Job
At the end of the day make a huddle and say, “Good job, team!”

Math
How many players on each team? How many players in all?
How long is a football field?
How many points for a touchdown? Field goal? Safety?
How long is a quarter? How long is the entire game?
How many yards in a first down?

Estimation
Let children estimate what they think the total score will be. After the game determine who guessed more – less - the closest?

Art
Put out the scrap box and let children make pennants, hats, pompoms, and other paraphernalia.

Football Practice Game
Cut footballs out on the fold similar to the one shown. Write math facts on the front and the answer inside.
*These can be used for phonics, numerical order, question and answers, etc.


NFL
What does "NFL" stand for? Download a copy of the team logos (Mr. Google will help you) and make a visual matching game or memory game.

SPIDERS AND BATS, OH MY!

Over the next few days I'm going to share activities that you can do with plastic spiders and bats. Spiders and bats are a good substitute for scary things this time of year. They are also cheap, plentiful, and perfect for hands-on activities. "PLAYFUL AND CHALLENGING" is a buzzword in early childhood, so here are some ways that these plastic rings meet standards and engage children.

Note! You can adapt these activities to any small toys or seasonal objects.
1. Kids love little toys. You’ll easily capture their interest with bat and spider rings.
2. Instead of tapping a key, children will be using multiple senses.
3. These activities can be adapted to different skills and age levels.
4. Children can work with a partner or use these materials independently in a center.
5. You can integrate STEM with facts about spiders and bats and math activities. You can also use them as a springboard for art and writing.

On a more personal level, you have given me something to do and have entertained me for the past week! I can’t tell you how much fun I’ve had trying to come up with ways to connect these plastic toys with learning activities that children will enjoy! Someone once remarked, “Dr. Jean, you take something simple and milk it for all it’s worth.” Well, I’m certainly “milking” these plastic toys for all they are worth. However, it’s a good reminder that you, too, can take seasonal objects (heart erasers), natural items (leaves), and other plentiful items and turn them into a learning opportunity!

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?"

HOW MANY DAYS?

It’s getting close to winter break! I wonder if the children know that you are even more excited than they are! Here are some math activities to keep them engaged over the next few days.


Magic Number

Children stand in a circle and begin counting off. When you get to 25 (Christmas Day) that child must sit down. Continue counting until one child is left.


Mingle Jingle
Children tiptoe quietly around the room as they whisper, "Jingle, jingle." When the teacher calls out a number, they must form groups with that amount. Those students who are leftover can do a jumping jack or other silly movement. Continue having the children mingle and jingle and form different sets.

                                 

Shopping

Materials: advertisements from toy stores, grocery stores, or discount stores, paper, pencils, scissors, glue

Write questions similar to those below on a chart. Children fold a sheet of paper into fourths and then write a number in each section. Then they look through the advertisements and cut out an object that answers each question.

1. What costs less than $10.00?
2. What costs more than $100.00?

3. If you had $20 what would you buy for your family?

4. What would you like to buy for yourself? How much does it cost?


5. Draw a T-chart on the back. On one side write "wants" and on the other side write "needs." Children cut out pictures (or write words) for things they actually need and things they'd like to have.
                                   

Seasonal Shapes
Take a walk around the school and look for different shapes in seasonal objects. Can they find a circle? Triangle? Rectangle? Square? Cube? Cone? Sphere?
*Let them make a shape collage by cutting objects out of advertisements and catalogs.


Estimation Jar
Before children enter the classroom fill a jar with seasonal candy or small toys. Invite them to look at the jar and write their “estimate” on a sheet of paper. At the end of the day empty the jar and count the contents. Who guessed more? Who guessed less? Who guessed the closest amount?
