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.
