6. ### Humpty Dumpty's Mystery Fall

• Resource ID: TXLS056
• Grade Range: 1
• Subject: Math

Students will listen to the story of Humpty Dumpty and share what they know about the nursery rhyme character. Then, they will help solve the math mystery of Humpty Dumpty and determine the number of broken eggs by finding the missing addend.

7. ### Dividing Fractions

• Resource ID: TXLS033
• Grade Range: 5
• Subject: Math

Students will model dividing unit fractions and whole numbers.

8. ### Making Ten is Easy as Pie!

• Resource ID: TXLS021
• Grade Range: 1
• Subject: Math

Students will practice composing 10 by interacting with a counting story, playing a dice game with ten frames and response sheets, and participating in a small group to extend the learning with three addends.

9. ### Area of Composite Figures

• Resource ID: TXLS012A
• Grade Range: 7
• Subject: Math

Students will progress through performance tasks to strengthen their understanding of composite figures. During the performance tasks, students will refer to blueprints to find missing dimensions and solve for composite area.

10. ### Compound Probability: Independent vs. Dependent Events

• Resource ID: TXLS044
• Grade Range: 7
• Subject: Math

Students will review steps for solving compound probability problems through an activity involving doughnuts. Students will then determine the difference between independent and dependent events through compound probability task cards. To encourage students to work through their struggle, students will rate themselves on a scale measuring effort and achievement at the end of the lesson.

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

• Resource ID: TXLS052
• Grade Range: 1
• 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.

12. ### Comparing Fractional Parts

• Resource ID: TXLS043
• Grade Range: 2
• Subject: Math

Students will participate in whole-group and small-group instruction as they collaborate and use manipulatives, visuals, and hands-on activities to explore fractional parts. Ultimately, students will understand that when dividing a whole into fractions, the smaller the fractional part, the greater the number of parts, and the larger the part, the fewer the number of parts.

13. ### Polygons and Quadrilaterals

• Resource ID: TXLS121
• Grade Range: 2
• Subject: Math

Learners will engage in higher level thinking and student-centered activities by building on prior knowledge of geometry, actively listening to a polygon story, and applying the new vocabulary through various hands-on rotations.

14. ### Subtraction on the Move

• Resource ID: TXLS140
• Grade Range: 2
• Subject: Math

The students will participate in a number talk focused on subtraction with the subtrahend of nine. Then they will be paired to rotate around the room working subtraction problems with and without regrouping.

15. ### Time Using the Z Method

• Resource ID: TXLS042
• Grade Range: 4
• Subject: Math

In small groups, students will calculate elapsed time using the Z method. This method helps students better understand the importance of start time and end time when performing elapsed-time calculations.

16. ### Area of Composite Figures

• Resource ID: TXLS039
• Grade Range: 7
• Subject: Math

Student groups will work collaboratively using the appropriate formulas to find the area of simple figures and combine the area of each shape to find the area of composite figures in real-world situations.

17. ### Models of Multiplication

• Resource ID: TXLS151
• Grade Range: 3
• Subject: Math

Students will solve one-step multiplication problems using various multiplication strategies such as objects, pictorial models, arrays, equal groups, repeated addition, and number lines.

18. ### Subtraction Seekers

• Resource ID: TXLS091
• Grade Range: 1
• Subject: Math

Students will be introduced to subtraction in an inquiry-based lesson that uses concrete examples and allows students to explore through different settings and scenarios.

19. ### Diagramming Dinosaurs

• Resource ID: TXLS098
• Grade Range: 7
• Subject: Math

Students will use a verbal representation to explore a constant rate of change in the size of dinosaurs over a period of time and represent their data by graphing.

20. ### Analyzing Bar Graphs: Candy Machines

• Resource ID: TXLS057
• Grade Range: 5
• Subject: Math

Working in groups, students will examine a bag of candy to determine if the machine that bags the candy is working properly. They will organize data on the colors of the candy in a frequency table and a bar graph. They will calculate the fraction of each color in the bag and compare the fractions to a quota set up by the factory to determine if the machine needs maintenance. Students will create a report about their findings, write a question that requires students to interpret data represented in a bar graph, and reflect in their journals.
