How To Teach Kids To Read A Thermometer

When teaching kids how to read a thermometer, it is important to also teach them why it is important to know how to read a thermometer. Before teaching kids how to read a thermometer, they need to understand elementary math skills, like counting by 10s, and noticing and understanding that the weather changes from day to day. By teaching children how to read a thermometer, you can help them understand temperature and how it changes and you can show them that they can check the temperature every day by themselves.

Step 1

Review with children how to count by 10s. Start at zero and count to 100.

Step 2

Explain to children, while holding up a large thermometer, that thermometers count by 10s. Ask specific kids to point out where certain numbers are, such as 40 or 60.

Step 3

Point out the smaller marks in between each number. Explain that the largest mark that is in between each number is half way between the number below it, and the number above it. For example, the largest mark between 20 and 30 is 25.

Step 4

Explain to the kids that each small mark goes up by one. There are nine small marks between each two numbers (1-4 and 6-9) and one larger make which we already know as the middle mark. Point out specific numbers like two marks above 90 is 92, or seven marks above 10 is 17.

Step 5

Talk to the children about the red line in the middle of the thermometer. Explain that it is either mercury, alcohol, or a similar chemical that interacts with the temperature outside, or how hot it is, which makes the red line move up or down. The number that the red line stops at is the number of the current temperature. Explain how if the red line goes up into higher numbers, it is getting hotter, and if it goes down to lower numbers, it is getting colder.

Step 6

Note what temperature the thermometer says inside with the kids, then place the thermometer outside and let it sit for a couple hours. Show the kids the difference on the thermometer, compared with the difference in how the temperature felt between inside and outside.

TL;DR (Too Long; Didn't Read)

Do multiple exercises explaining how thermometers go up by 10s before introducing the small marks in between the numbers. Practice reading a thermometer daily to ensure the kids understand the concept.
