1. ### Modeling and Solving Two-Step Equations

• Resource ID: TXLS012-0
• Subject: Math

Students will use various materials to create models of two-step equations. Then, they will take an equation, create their own model, and solve for the variable from the model.

2. ### Equations and Inequalities

• Resource ID: TXLS034-0
• Subject: Math

Using a graphic organizer, students will write and solve a one-variable, two-step equation using the distributive property. They also will draw a picture and justify their solution.

3. ### Does Paper Have Volume?

• Resource ID: TXLS029-0
• Subject: Math

Students will be involved in a problem-solving lesson to determine if paper has volume, find the volume of a piece of paper and a ream of paper, and determine how many pieces of paper will fit inside their classroom.

4. ### Open House: Challenger Oaks—Geometry by Design

• Resource ID: TXLS170
• Subject: Math

Teachers will engage their students in classifying 2-dimensional shapes through a real-world experience. Students will review, design, and use technology as they classify figures using common attributes.

5. ### Summarizing as a Reading Strategy

• Resource ID: TXLS104

Students work collaboratively using reading and comprehension skills to demonstrate their mastery of summarizing a text or piece of literature.

6. ### Discovering the Ratio of Pi

• Resource ID: TXLS031A-0
• Subject: Math

Students will discover the ratio of pi by relating the circumference to the diameter of various circles. Students will use this ratio to approximate the formulas for circumference.

7. ### Volume of Triangular Prisms

• Resource ID: TXLS045-0
• Subject: Math

Students will use hands-on manipulatives to discover the connection between the shape of the base and the height to determine the volume of a prism.

8. ### DNA Sequencing

• Resource ID: TXLS128-0
• Subject: Science

In this lesson, students will investigate how gene expression is a regulated process controlled by DNA and the interpretations of codons through translation.

9. ### Convergent Plate Boundaries

• Resource ID: TXLS135-0
• Subject: Science

Students will design and test models that will identify crustal features formed by convergent plate boundaries.

• Resource ID: TXLS006-0
• Subject: Science

Students will use hover pucks to measure speed over a distance of 6 meters. Once speed has been calculated, velocity will be determined using the same data. Finally, students will be able to label all points of acceleration.

11. ### Building a Watershed

• Resource ID: TXLS122-0
• Subject: Science

Students will model the effects of human activity on watersheds.

12. ### It’s All About the Bend, No Breaking

• Resource ID: TXLS052-0
• Subject: Math

Students will experiment with choosing tools to measure around a previously created pet habitat in preparation for choosing appropriately sized food bowls. Students will use a graphic organizer to record tools chosen and why they were or were not a good choice for continuous measurement.

13. ### Interpreting Division with Remainders

• Resource ID: TXLS004-0
