Gather three types of beans, such as lima, pinto, and navy. See Lesson 3 Materials Preparation.
Display the class number line (0–130) where all students can see it and can reach it with a pointer.
Attach a desk number line (0–100) to each student's desk to use throughout the year.
Display the Math Practices page where all students can see it.
Have the following tools readily available for the Daily Practice and Problems items in this unit:
- connecting cubes
- number lines
- individual clocks
- Clock
Master prepared with only the hour hand. See the Teacher Notes for DPP item E or the Lesson 1 Materials Preparation.
| LESSON | SESSIONS | DESCRIPTION | SUPPLIES |
|---|---|---|---|
LESSON 1First Names |
3 | This teacher-guided lab is an exploration of the lengths of students' first names. The class collects and organizes data in a table and graph so students can make predictions and generalizations about a population, specifically, the length of first names. |
|
LESSON 2Number Line Target |
1 | This lesson introduces students to the class number line and their desk number line. These tools will be used by the class throughout the year. Students discuss the similarities and differences between the class number line and their desk number line. They play a game to practice addition and keep score using a number line. |
|
LESSON 3Kind of Bean |
3 | Students make predictions and generalizations about a population by studying a sample. In the Kind of Bean Lab, students take a scoopful of dry beans from a population of beans. After students sort and count the beans, they record, organize, graph, and analyze their data. |
|
LESSON 4Who Is Right? |
1 | Students analyze and graph bean population data similar to the Kind of Bean Lab data from Lesson 3. Students compare data representations to determine which data matches a mystery tub of beans. |
|
LESSON 5Using Picture Graphs |
1–2 | Students solve one- and two-step word problems using sample data represented in scaled picture graphs and tables. |
