Scales
Learn to read scales by identifying tick mark values on thermometers, weight scales, and rulers using labeled numbers and differences in Grade 6 math.
Key Concepts
Property A scale is a display of numbers with an indicator to show the value of a certain measure. To read a scale, we need to discover the value of the tick marks on the scale.
Examples A Celsius thermometer shows ticks for every $2$ degrees between $10^\circ\text{C}$ and $20^\circ\text{C}$.
A weight scale shows a tick mark for every $5$ kilograms between $50\operatorname{kg}$ and $100\operatorname{kg}$.
Common Questions
What is a scale in 6th grade math?
A scale is a display of numbers with an indicator that shows the value of a certain measure, like a thermometer or weight scale. To read a scale, students must figure out what each tick mark is worth by finding two labeled numbers and calculating the difference between them.
How do you find the value of tick marks on a scale?
To find the value of tick marks, locate two labeled numbers on the scale and subtract them to find their difference. Then divide that difference by the number of intervals between those labeled marks to determine what each tick mark represents.
What are examples of scales used in math?
Common scale examples include a Celsius thermometer with ticks every 2 degrees between 10°C and 20°C, a weight scale with ticks every 5 kilograms between 50 kg and 100 kg, and an inch ruler with tick marks representing fractions like 1/8 of an inch.
Why is reading a scale important for 6th graders?
Reading scales accurately is a key measurement skill used in real-life situations like checking temperature or measuring recipe ingredients. In Saxon Math Course 1, understanding tick mark values helps students interpret data and solve problems involving measurement.
