Section B: Practice Problems Count and Compare Groups of Images
Section Summary
Details
In this section, we counted many different groups of things. We kept track of which ones we counted to make sure that we only counted each thing one time.
We also compared the number of things in groups using “more”, “fewer”, and “the same number.”
Sometimes we could just see that there were more.
There are more cups than straws.
Sometimes we had to match or count to figure out which group had fewer.
6 dots is fewer than 7 dots.
Problem 1 (Lesson 7)
How many dots are there?
Problem 2 (Lesson 8)
Are there more apples or plates?
Problem 3 (Lesson 9)
Circle the 5-frame that has more dots.
Circle the group that shows fewer things.
Problem 4 (Lesson 10)
Circle the 3 groups that show more than this 5-frame.
Circle the 3 groups that show fewer than this 5-frame.
Problem 5 (Lesson 11)
Here is a drawing.
Draw a picture with more things.
Draw a picture with fewer things.
Problem 6 (Exploration)
Make a set of cards with images. Some cards can have the same number of images and some cards can have different numbers of images.
Trade your cards with a partner.
Turn over two cards and decide if they have the same number or if one has fewer and one has more.
Problem 7 (Exploration)
Are there fewer students than chairs? Explain how you know.
