What this lesson shows
A beaker and a thermometer read like a number line standing up.
The worked example
The lesson works this one step by step: beaker 230 mL, thermometer 74°F. Then your kid tries one like it on paper.
The steps
- A number line standing up
- Find the number below
- Count up the marks
Helping at home
Find what each mark is worth first: count the marks between two numbers. Then start at the number just below the top of the liquid and count up the marks.
If your kid gets stuck
How much is one mark worth?
Watch it with Lux
With Lux, this lesson is a narrated video and a printed page your kid works on. Then Lux helps with the same math on their own worksheet, one question at a time.
Standards
- Common Core 3.MD.A.2
Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem.
