Our Ounces, Pounds, and Tons Lesson Plan applies the concepts of measuring the mass/weight of objects to ounces, pounds, and tons. With an interactive activity, students practice through meaningful game play with manipulatives. Generalize the learned concepts by weighing each student and converting their weight into ounces.
Sample Classroom Procedure / Teacher Instruction
- Ask students: What is the heaviest item you have ever lifted with your hands? How much do you think it weighed?
- Allow for responses and discussion.
- Ask students: What is the lightest item you have ever lifted with your hands? How much do you think it weighed?
- Allow for responses and discussion. Introduce ounces, pounds, and tons.
- Distribute Ounces, Pounds, Tons content page. Read and review the information with the students. Use extra examples to help students understand the conversion of ounces to pounds, etc.
- Carefully explain how the remainders are turned to ounces or pounds, and 16 ounces change to one pound, and 2,000 pounds change to one ton. Use the additional resources to enhance understanding.
- Distribute Activity pages. Read and review the instructions. Carefully explain the samples and the calculation of the “New Total”. Pair students. Distribute scissors. (Decide if each student cuts apart two copies of the weights, or use one set of weights for each pair.) Give students sufficient time to play the game.
- When completed, randomly check and review some of the students’ responses.
- Distribute Practice page. Check and review the students’ responses.
- Distribute the Homework page. The next day, check and review the students’ responses.
- In closing, use a scale and weigh each child. The students will then turn their weights into ounces. In addition, ask students various questions such as how many of them would equal one ton, if they added all of the weights in the room what would the weight be, etc.
- Give time for students to do the calculation, allowing them to share their responses.
