测量折线图
Description
Make a line plot to display measurement data in fractions of a unit (1/2, 1/4, 1/8); solve problems involving addition and subtraction of fractions using line plot data
Mastery Evidence
- Create a line plot of seed growth measurements in 1/8-inch increments
- Use a line plot to find the difference between the longest and shortest specimens
- Calculate the total length of all items in a line plot by adding the fractional measurements
Assessment Prompt
If your child records caterpillar lengths as fractions of an inch and plots them on a number line, can they work out the total length of three caterpillars by adding the fractions from the plot?
