| LESSON | SESSIONS | DESCRIPTION | SUPPLIES |
|---|---|---|---|
LESSON 1Measuring Volume |
1–2 | Students discuss volume using the context of the Aesop's Fable The Crow and the Pitcher. The procedure for finding the volume of an object by displacement is modeled for students. Students estimate and measure the volume of small objects. |
|
LESSON 2Fill It First Game |
1 |
In this game, teams of students compete against each other to predict the volume of all the marbles in a graduated cylinder as one to four marbles are added to their cylinders. The winner is the team with the highest score after each team has added a total of 20 cc of marbles. This game prepares students for the lab in Lesson 3 Volume vs. Number. It provides practice measuring volume by displacement and also provides the context for the data collection and predictions students will make in the lab. |
|
LESSON 3Volume vs. Number |
3–4 | Students use the TIMS Laboratory Method to collect, organize, graph, and analyze data of the volume of different numbers of marbles. They look for patterns in the data that will help them estimate the volume of a given number of marbles. Lesson 2 Fill It First Game provides the context for the lab. |
|
LESSON 4Units of Volume |
1 | Students express the volume of containers using different units of metric measure, including liters, milliliters, and cubic centimeters. |
|
LESSON 5Writing Rules |
1–2 | Students identify relationships between units of measure (e.g., liters and milliliters) by looking for patterns in function tables and writing rules to express the relationships. |
|
LESSON 6Sandwich Mass |
2–3 | Students find the mass of a sandwich using a two-pan balance. They then see how the mass changes as bites are taken out of the sandwich and use patterns in the data to predict the number of bites in the whole sandwich. A discussion in the Student Guide helps students explore the distinction between mass and weight. |
|
LESSON 7Patterns and Problems |
1–2 | Students complete a series of word problems that review patterns, function machines, and graphing. |
