It’s All About the Bend, No Breaking
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 to explain why those tools were or were not a good choice for continuous measurement.
Subtraction Seekers
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.

Humpty Dumpty's Mystery Fall
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.

Distributive Property
Students break an array apart to represent the sum of two multiplication facts, showing the distributive property.
Texas Essential Knowledge and Skills (TEKS) Related to the Unit
As we looked at the vertical alignment document available to teachers through the Texas Education Agency and regional TEKS resource pages, it became evident why students struggle with this standard. The skills and knowledge within this standard are not addressed in the second-grade TEKS. Students are also required to use multiple skills to correctly calculate the answer using the distributive property. The chosen standard is identified as a third-grade readiness standard, which means that the intent is to help students develop a deep understanding of how to effectively use these skills in mathematics. This deep understanding is desired to help students at the fourth-grade level since the standard is identified as a supporting standard.

Analyzing Data Using a Dot Plot
Students will construct a dot plot using data collected on the faces of a cube after it is rolled. Students will then use a key to change the data to represent a larger population.

Understanding the Equal Sign and Balancing Equations
Students will apply addition strategies as they complete four different station rotations to help understand that the equal sign represents a relationship where the expressions on each side of the equal sign represents the same value.
Exploring Number Sense
Students will use manipulatives and a number path to identify numbers one less than or more than a given number.
Students Working in Their Group
Balancing Act
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.
Students participating and listening to teacher instructions
The Shapes Around Us
Students will make connections between real-world objects and the attributes of two-dimensional shapes.
Students working in their group
Problem-Solving Pet Store
Using a pet store theme, students will work in groups to solve real-world problems to grasp the concept of multi-step multiplication and division word problems.
Unlocking Strategies to Multiply and Divide within 100
Students will work in cooperative groups to confidently solve one and two-step multiplication and division problems up to 100 using arrays, strip diagrams, and equations.
Multiplication at the Market
Students will solve one-step multiplication problems using concrete objects, pictorial models, arrays, and equal groups.
