Compare temperatures above and below zero

Learning Objectives Identify temperatures as above, below, or exactly at zero degrees. Represent temperatures on a vertical or horizontal number line. Compare any two given temperatures, including positive, negative, and zero values. Use inequality symbols (<, >, =) to express relationships between different temperatures. Order a set of temperatures from coldest to warmest or warmest to coldest. Explain how the position of a temperature on a number line relates to its value and warmth. Ever wonder why some places need thick coats and others just a t-shirt? 🥶☀️ It all comes down to temperature! In this lesson, we'll explore how to compare different temperatures, especially those above and below the freezing point of zero. Understanding how to compare these value...

TermDefinitionExample TemperatureA measure of how hot or cold something is, typically measured in degrees Celsius (°C) or Fahrenheit (°F).The temperature outside is 15°C, which feels cool. Zero Degrees (0°)The reference point on the temperature scale. For Celsius, 0°C is the freezing point of water.Water freezes at 0°C, so if the temperature drops to 0°C or below, puddles might turn to ice. Above ZeroTemperatures that are warmer than 0°. These are represented by positive numbers.A temperature of 5°C is above zero, meaning it's warmer than freezing. Below ZeroTemperatures that are colder than 0°. These are represented by negative numbers.A temperature of -3°C is below zero, meaning it's colder than freezing. Positive IntegerA whole number greater than zero (e.g., 1, 2, 3...). In...

Comparing Positive Temperatures For any two positive temperatures $T_1$ and $T_2$, if $T_1$ is further from zero than $T_2$ (i.e., $T_1$ has a greater numerical value), then $T_1 > T_2$. When comparing two temperatures both above zero, the one with the larger number is warmer. For example, $10°C > 5°C$ because 10 is greater than 5. Comparing Negative Temperatures For any two negative temperatures $T_1$ and $T_2$, if $T_1$ is further from zero than $T_2$ (i.e., $T_1$ has a greater absolute value), then $T_1 < T_2$. When comparing two temperatures both below zero, the one with the smaller number (further to the left on a number line) is colder. For example, $-10°C < -5°C$ because -10 is colder than -5. Comparing Positive and Negative Temperatures Any positive...
