Students will work collaboratively with a partner to discover what is a line of symmetry.

2. ### Convergent Plate Boundaries

• Resource ID: TXLS135
• Subject: Science

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

3. ### Let's Talk Turkey

• Resource ID: TXLS136
• Subject: Math

Students will work collaboratively to apply different strategies such as pictorial representations, part-part-whole, number sentences, and open number lines to solve Thanksgiving-themed one-step and multi-step word problems.

4. ### Effects of Force

• Resource ID: R4SCI0048
• Subject: Science

A tier 1 force and motion instructional resource for grade 4.

5. ### Using Geometric Concepts and Properties to Solve Problems

• Resource ID: M7M3L15
• Subject: Math

Given pictorial representations, the student will use geometric concepts and properties to solve problems from art and architecture.

6. ### Balancing Act

• Resource ID: TXLS205
• Subject: Math

Students use a pan balance model and manipulatives to identify a total that balances two parts. The use of the pan balance will help to develop the concept of equality. Students will develop the language of equality by reading and identifying the following expressions; balances, is the same as, is equal to, and equal before the symbol for equality is introduced. Students will identify an unknown part in a balance situation. Students will communicate ideas, explain, and justify how they solved problems.

8. ### Learning the Two-Step Equation

• Resource ID: TXLS038-0
• Subject: Math

Students will physically represent an array, a strip diagram, and an equation before working collaboratively in small groups to create these three models using a word problem.

9. ### Birthday Conundrum

• Resource ID: TXLS025-0
• Subject: Math

Students will work together to determine the amount of each snack item it will take to feed the guests at a birthday party using different methods of multiplication representation.

10. ### Just Graph It!

• Resource ID: TXLS030-0
