Does Paper Have Volume?
 Resource ID: TXLS029
 Grade Range: 7
 Subject: Math
Students will be involved in a problemsolving 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.

Just Graph It!
 Resource ID: TXLS030
 Grade Range: 3
 Subject: Math
Students will be involved in a problem solving lesson in which they are to visually represent previously collected survey data.

How Does the Cookie Crumble?
 Resource ID: TXLS031
 Grade Range: 6
 Subject: Math
Students will selfdiscover how to multiply mixed numbers by using background knowledge of estimation, computations, and real world application of a recipe.

Interpreting Division with Remainders
 Resource ID: TXLS004
 Grade Range: 4
 Subject: Math
Students will be given various one and twostep word problems and asked to interpret the remainder. Students will use foldables and anchor charts to determine under which category (“Drop the Remainder,” “Add One to the Quotient,” “Share the Remainder,” or “The Remainder is the Answer”) the question will fall. After completing that portion of the lesson, students will solve division problems and determine which type of remainder question they are working with. They will use Plicker ^{©} cards to display their answers so the teacher can have immediate formative assessment data.

Distributive Property
 Resource ID: TXLS010
 Grade Range: 3
 Subject: Math
Students break an array apart to represent the sum of two multiplication facts, showing the distributive property.

Discovering the Ratio of Pi
 Resource ID: TXLS031A
 Grade Range: 6–7
 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.

Dividing Fractions
 Resource ID: TXLS033
 Grade Range: 5
 Subject: Math
Students will model dividing unit fractions and whole numbers.

Modeling and Solving TwoStep Equations
 Resource ID: TXLS012
 Grade Range: 7
 Subject: Math
Students will use various materials to create models of twostep equations. Then, they will take an equation, create their own model, and solve for the variable from the model.

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.

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.

Volume of Triangular Prisms
 Resource ID: TXLS045
 Grade Range: 7
 Subject: Math
Students will use handson manipulatives to discover the connection between the shape of the base and the height to determine the volume of a prism.

Equations and Inequalities
 Resource ID: TXLS034
 Grade Range: 7
 Subject: Math
Using a graphic organizer, students will write and solve a onevariable, twostep equation using the distributive property. They also will draw a picture and justify their solution.

Learning the TwoStep Equation
 Resource ID: TXLS038
 Grade Range: 3
 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.
