green color bottle = 250 ml.
yellow color bottle = 750 ml.
Explanation:
In the above-given question,
given that,
Liquid volume is a measure of how much liquid a container can hold.
containers of liquids that are measured in milliliters and liters.
I am assuming the bottles with liquids.
Flavored water bottle = 530ml.
non-flavored water bottle = 1 liter.
orange color bottle = 500 ml.
green color bottle = 250 ml.
yellow color bottle = 750 ml.
Question 2.
Circle an item that you can use as a benchmark for 1 liter.
Answer:
The item is non-flavored water bottle.
Explanation:
In the above-given question,
given that,
Liquid volume is a measure of how much liquid a container can hold.
containers of liquids that are measured in milliliters and liters.
I am assuming the bottles with liquids.

Question 3.
Put a star next to an item that you can use as a benchmark for 500 milliliters.
Answer:
The item is orange color bottle.
Explanation:
In the above-given question,
given that,
Liquid volume is a measure of how much liquid a container can hold.
containers of liquids that are measured in milliliters and liters.
I am assuming the bottles with liquids.
so the 500 ml contains orange color bottle.

Sorting Fractions
Family Note Today your child looked for patterns to help order fractions with the same numerator. Children recognized that as a fraction’s denominator gets larger the fraction gets smaller. They were able to write this as a rule for ordering fractions with the same numerator. For Problem 1, your child will sort a set of fractions into two groups: fractions greater than 1 and fractions less than 1. In Problem 2, your child will look for patterns to help sort any set of fractions into these two groups.
