 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.

Adding Fractions on a Number Line
 Resource ID: TXLS113
 Grade Range: 4
 Subject: Math
Students will work collaboratively in small groups to create number lines, and then use those number lines to model a realworld situation.

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.

Solving Rational Equations
 Resource ID: TXLS037
 Grade Range: 11
 Subject: Math
Students will discuss and formulate an equation to solve an engaging realworld problem. They will use manipulatives to describe how to find the common denominator they need to solve the equation. They will break up into groups and solve for a more complicated problem.

What's on the Menu?
 Resource ID: TXLS110
 Grade Range: 4
 Subject: Math
Students will practice solving one and twostep problems in a simulated realworld situation by calculating the costs of different Thanksgiving dinners.

Finding Common Denominators
 Resource ID: TXLS108
 Grade Range: 5
 Subject: Math
Students will work collaboratively to explore and sketch solutions to realworld addition problems involving fractions with unlike denominators. Students will be given the opportunity to use manipulatives and participate in group discussions to reflect on their learning.

Rate of Change
 Resource ID: TXLS125
 Grade Range: 9
 Subject: Math
The students will determine the rate of change from tables and graphs by using the slope formula. The students will discover and interpret the realworld applications of rate of change.

Make a Hit with Decimals
 Resource ID: TXLS070
 Grade Range: 4
 Subject: Math
Students will compare and order decimals using baseball batting statistics. Through discovery, students will determine the top six out of eleven players to be recruited for the school’s baseball team, present their findings, and explain reasons for their orderings. From students’ explanation, strategies for ordering decimals will be determined and used to adjust subsequent lessons.

Laws of Exponents
 Resource ID: TXLS105
 Grade Range: 9
 Subject: Math
Students will discover the laws of exponents using problemsolving skills.

Organizing Olympic Outcomes
 Resource ID: TXLS095
 Grade Range: 4
 Subject: Math
Students will explore frequency tables, dot plots, and stem and leaf plots by creating different representations from a given set of data points.

Roll With It
 Resource ID: TXLS066
 Grade Range: 6
 Subject: Math
Students will experience a handson lesson regarding ratios. While doing this, students will deepen their understanding of the concepts of ratios.

Give a Hoot . . . Fraction Scoot
 Resource ID: TXLS133
 Grade Range: 5
 Subject: Math
Students will add and subtract unlike denominators using pictorial models and manipulatives. During the lesson, they will use both group and independent work to build confidence as they use a variety of formative assessments to check for understanding. The final activity in the lesson has both application of the concepts being taught and a personal reflection of understanding.

Lines of Symmetry
 Resource ID: TXLS107
 Grade Range: 1
 Subject: Math
Students will work collaboratively with a partner to discover what is a line of symmetry.

Let's Talk Turkey
 Resource ID: TXLS136
 Grade Range: 2
 Subject: Math
Students will work collaboratively to apply different strategies such as pictorial representations, partpartwhole, number sentences, and open number lines to solve Thanksgivingthemed onestep and multistep word problems.

Balancing Act
 Resource ID: TXLS205
 Grade Range: K
 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.

The Picture Graph Party
 Resource ID: TXLS0930
 Grade Range: K
 Subject: Math
Students will explore and create picture graphs through collaboration and group work.

Learning the TwoStep Equation
 Resource ID: TXLS0380
