Valentine Marbles

This Valentine Marbles lesson plan also includes:

if you've ever had to guess how many items were in a jar, then this problem is for you! With a big jar full of red and white marbles, does picking a sample of 16 allow your learners to get a good estimate on the percentages of each color? Different samples are provided. Your mathematicians will need to answer questions to determine if those results coincide with the actual percentage. The problem includes great commentary and solutions that can be used as support for the lesson.
