The period of the senior preschool and primary school age is a favorable time for the formation of the notion of measurement. Children 5 - 8 years old learn about the appointment of various measuring instruments and devices (ruler, protractor, watch, scale, thermometer), actively learn the techniques of carrying out various measurements, consciously use the concepts denoting units of measurement. Sometimes it is difficult to explain the principle of the operation of a device, so parents and teachers are helped by models that help the child understand how the device for measuring functions.
We will tell you step by step how to make a thermometer from cardboard. Such a paper thermometer can be used in classes to familiarize with the environment in the kindergarten or at the lessons of mathematics and natural history in the primary school classes when managing the weather calendar . Also a cardboard thermometer made by one's own hands can be hung on the wall in the children's room. Thanks to the model, it will be easier for the child to understand what is zero, what negative and positive numbers mean, to establish a connection between the readings of the device and changes in nature or in bodily sensations.
We need:
- light cardboard or semi-cardboard;
- thick threads of red and white color;
- a needle with a large eye;
- ruler,
- automatic pen or bright felt-tip pen;
- pencil.
Completing of the work:
- Cut out a cardboard strip of 12x5 cm.
- We put on the scale markings in pencil from -35 degrees to +35 degrees Celsius, then circle with a pen or felt-tip pen. If you have a printer, you can download a scale image from the Internet or create it yourself, and then print it on paper and paste a printout onto the cardboard for strength. Such a model will be more aesthetic.
- We connect the ends of the red and white threads together.
- In the needle, we insert a red thread, piercing the lowest part of the thermometer scale. Then we insert a white thread and pierce the needle with the upper point of the scale. On the back of the paper thermometer, straighten the ends of the threads. The model for measuring the air temperature is ready!

Explaining to the child how the device measuring the air temperature operates, you can play with it in the game with the movement of the two-colored thread "What happens?" The red indicator is on the minus sign - the child can list what is happening in nature: "It's cold outside, puddles covered with ice, people put on warm jackets, hats, mittens, "etc. If the indicator is at plus temperature, the child remembers what happens in nature, when it is warm.
For children's story-role games "Home" and "Hospital" you can make a medical thermometer from cardboard with your own hands.
How to make a thermometer from cardboard?
- On the cardboard we draw a form similar to the form of a medical thermometer for measuring body temperature. We plot the scale with the corresponding temperature values.
- In the lower indicator of 35 degrees, insert a red thread, in the upper indicator of 42 degrees, insert a white thread. Also we fasten the threads together, we cut off the excess.
- When the model of the medical thermometer is ready, it would be good to explain to the child what body temperature is in healthy people, what is in patients, which means "elevated", "high" and "low" temperature. Now you can measure the temperature of all the "sick" dolls, and also use a thermometer in games with girlfriends. Who knows, maybe in the future your baby will want to be a medical worker, thanks to the children's games ?!
Such models that contribute to the mental development of the child, it is very good to do, involving the children themselves in making them. Crafts made with their own hands, especially pleased with the small masters and encourage to treat the objective world more responsibly and carefully.
