Progression of Lessons

Lesson 1

Organize to find how many and compare.

Organize and represent data to compare two categories.

Sort to represent and compare data with three categories.

Organizing on a number path helps me count and compare.

I see my choice on the graph! More of us like to listen to music.

I can tell there are more blue cubes than red cubes. 8 is greater than 4.

Find the total number of data points and compare categories in a picture graph.

Organize and represent categorical data.

Lesson 6

Use tally marks to represent and compare data.

I counted the checkmarks to find out that there are 12 butterflies. There are the same number of small butterflies and large butterflies, 3 = 3.

Look! I have 41 cubes. I sorted them by color. I chose to show my collection by coloring a graph.

Tally marks show groups of 5. There are 5, 6, 7, 8, 9 animals! There are fewer stop signs than bridges, 6 < 9.
