| LESSON | SESSIONS | DESCRIPTION | SUPPLIES |
|---|---|---|---|
LESSON 1Volume of Cube Models |
2–3 | Students are introduced to the concept of volume and learn to determine volume by counting connecting cubes. They use connecting cubes to construct different buildings that have a volume of eight cubic units and use number sentences to describe each building. |
|
LESSON 2Estimate Volume with Cube Models |
1–2 | Student pairs use connecting cubes to build models of classroom objects then estimate the volume of the objects by finding the number of cubes in their models. They compare the volume of the models to determine if their estimates are reasonable. |
|
LESSON 3Strategies to Find Volume |
2 | Students work with a partner to build cube models based on three-dimensional drawings. Students explore strategies, including skip counting and repeated addition, for finding the volume of cube models. |
|
LESSON 4Use Repeated Addition |
2–3 | Students find the volume of cube structures by skip counting and writing number sentences showing repeated addition. They build cube models from 3-dimensional drawings and compare them. In the Adventure Book, Manuel has exciting adventures in a dream where animals are changed into cube creatures. |
|
LESSON 5The Digital Clock |
2 | Students are introduced to reading time to the nearest hour and half hour on a digital clock. They match the time shown on an analog clock to the time on a digital clock. |
