Arithmetic and Geometry in the Playground

Many opportunities for counting on the playground exist.

It may seem a little strange to practice arithmetic and geometry without a notebook, eraser, and sharpened pencil, but it turns out that the playground is a wonderful way to learn arithmetic and geometry in a fun and experiential way and expose children to basic concepts from these worlds.

Unlike the motor skills that the children develop in the playground without the help of the parent, learning arithmetic and geometry on the playground requires the active involvement and mediation of the parent.

Arithmetic in the playground

In almost every area of our lives, we need mathematical calculations, so it is useful to familiarize yourself with numbers, quantities and basic arithmetic operations at an early age to help children with school accounting, provide them with a basis for mathematical thinking and not deter them from the profession.

If we look at the details of the playground, we can find many opportunities for practicing arithmetic skills, such as counting, more, less, equal, double, and more.

Here are some examples of how to take inventory on the playground:

Counting

For example, you can count up to ten when your child hangs on the bar, swinging in the swing, you can decide to count to twenty, and when the child reaches twenty, the child will descend from the swing.

Numeration 

You can number equipment or parts of equipment - how many swings are there? How many chains does each swing have? How many columns does the equipment have? How many ladders are there on the playground?

Comparisons

Comparison is the basis for understanding the concepts "greater than ..." and "smaller than ...". For example, to answer the question "How many more rungs are there on the nearest ladder compared to the far ladder?" - The first step is a comparison and one of the important comparisons in accounting is the comparison of quantities.

Why are comparisons important?

In everyday life, we constantly make comparisons. We decide on priorities in the actions we take, what is more urgent and more important, and what is less? What should be done first and what is next? We examine products that we want to buy by comparing different parameters - price, size, appearance. We examine ourselves in relation to others through different grades, degrees, achievements.

What parent hasn't heard "why did he get more than me?"

It is not surprising that this is how children speak because we also speak to them in a similar way:

"Why do not you behave as well as your brother?"

"Why did Sharon put more effort than you into the test?"

In most cases, these comparisons do not serve us and our children and may cause frustration ("Why does he succeed and I do not?"). But in some cases, comparisons are necessary to make informed choices, so it is very worthwhile to practice the comparisons, not necessarily in the accounting context.

In the playground, comparisons allow children to examine different parameters by which they choose the various equipment and the activity on them. This is where we can bring to their attention the diversity of the facilities, and examine the equipment in detail. Comparisons can be expressed in different areas of the playground, whether it's color, distance, altitude, texture, temperature, speed, size, time, and more.

Comparing quantities means presenting two sets of objects, and asking which group has more or fewer objects. When we compare two groups of items, in this case rungs on the ladder, we ask:

Which of the two ladders has more or fewer rungs?

How many more or fewer?

Most children can point to the larger or smaller group.

We take two ladders, one with seven rungs, and the second ladder with four rungs. In the question of how much seven is greater than four, we must create equality between seven and four. In order to create this equality, we must reduce the four-rung ladder to the four units on the second scale, ie, find each step on the four-step scale a mate on the seven-step scale, and count the remaining rungs, and then see that there are three stages that do not have a mate. Thus we will reach the result that the difference between seven and four rungs is three rungs.

A child who has not yet acquired the concept of equality cannot understand concepts of inequality (greater than / less than).

Multiplication

Older children can practice multiplication in the playground. For example, if there are 4 swings and each swing has two seats, how many seats are there in total? What exercise should we do?

Therefore, practicing counting games on the playground is a worthwhile venture. Ask the kids: what is more, swings or slides? How many pages does the tower have? What is the difference between the two slides?

Geometry in playground

If we ask children what they see on the playground, most of them will probably answer: "Slide, swing, tower, tunnel..." We are used to seeing the playground through the names of the equipment, but if we look deeper - we can see countless shapes and geometry figures hiding in the equipment themselves and between them, and the children can be exposed to other geometric concepts beyond the forms most of which they already know.

What is a geometric shape?

A geometric form is a shape described by a closed line enclosing part of a plane.

The main forms of engineering are a circle, a triangle, a square, a rectangle, a parallelogram, a trapezoid, and rhombus.

If you walk along the closed line that describes the geometric shape, you get back to the starting point. Such a closed line divides the plane into two parts: the section within the line, which is the interior of the geometric form, and the part outside the line.

Area and scope

The area within the enclosed line is the area of the geometry, and the length of the line is the perimeter of the shape.

Polygon, rib, and vertex

If the line that encloses the geometry is composed only of straight segments, the geometry is called a polygon.

Each straight segment of the line that encloses the polygon is called a rib, and each point where two ribs meet is called a vertex.

And so, without a notebook and without a sharpened pencil, you can enrich the children's vocabulary in the playground in terms of geometry: space, circumference, rib, vertex and more.

The geometric shapes are found in the playground in several degrees: the simple shapes are the surfaces or elements that the children know, such as the steering wheel, the handles in the swing, the rose leaf, the railing and the turnstile. The more complex forms are hidden shapes, that is, they need to be imagined a little because they are in the spaces between the elements or they are on a large scale that is hard to distinguish.

You can play with the children "look for the triangle" and find simple and complex shapes.

Lines

So far we have seen the shapes that make up the equipment or the various elements in the equipment. Now we'll look for lines of different types hiding in the equipment.
And there are many more lines in the playground, just look and see.

How to create geometric shapes 

We discovered a lot of shapes and lines in the playground, now we will learn how to create shapes.

Let's take these things to the playground: a thin rope (about four millimeters thick and ten meters long) and colorful stickers for marking on the rope.

For safety reasons, do not leave the rope unattended in the playground!

Most of the towers in the playgrounds are built of four columns. You can move the rope around the four columns and create a square. The geometric shape is the one that is enclosed within the rope.
For children, it is relatively easy to see the shapes formed on the ground. The flat forms are easy for them to absorb.

You can create triangles between any three columns, or pentagon with five columns. You can point out to the child the connections between the number of columns and the number of vertices and ribs.

You can compare the size of the shape ribs with your feet, or by placing the rope length of one rib on the other side and so on.

Older children can make shapes up high and not just on the ground. They can also find the ratio between the diameter of the tunnel and its perimeter, and find that the perimeter is slightly more than 3 times the diameter.

Older children can practice the multiplication table…

So, now you can see how the playground has become a laboratory for learning arithmetic and geometry, without a notebook and pencil.
