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.

Young Architects
 Resource ID: TXLS062
 Grade Range: 4–5
 Subject: Math
Students will explore area by finding square footage of the “dream home” they designed. They will use any method with which they feel confident, using skills that have been previously taught.

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.

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

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.

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.

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.

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.

Comparing Fractional Parts
 Resource ID: TXLS043
 Grade Range: 2
 Subject: Math
Students will participate in wholegroup and smallgroup instruction as they collaborate and use manipulatives, visuals, and handson 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.

Polygons and Quadrilaterals
 Resource ID: TXLS121
 Grade Range: 2
 Subject: Math
Learners will engage in higher level thinking and studentcentered activities by building on prior knowledge of geometry, actively listening to a polygon story, and applying the new vocabulary through various handson rotations.

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.

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 elapsedtime calculations.

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 realworld situations.

Models of Multiplication
 Resource ID: TXLS151
 Grade Range: 3
 Subject: Math
Students will solve onestep multiplication problems using various multiplication strategies such as objects, pictorial models, arrays, equal groups, repeated addition, and number lines.

Subtraction Seekers
 Resource ID: TXLS091
 Grade Range: 1
 Subject: Math
Students will be introduced to subtraction in an inquirybased lesson that uses concrete examples and allows students to explore through different settings and scenarios.

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.

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.
