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.

From Dogs/Not Dogs to Prisms/Not Prisms
Students will work in pairs, groups, and independently to sort and classify 2D and 3D shapes using formal geometric language. Students will have opportunities to explore the work of other groups to expand their thinking and find new ways that shapes can be sorted and classified. Students will engage in multiple conversations using accurate geometrical language to ask questions, explore a variety of reasonings, and share generalizations about shapes.
What Goes In, Must Come Out
Students will learn how to use an input-output table using real-world examples.
Decoding Word Problems
This lesson focuses on multi-step word problems involving division along with addition or subtraction. The students chunk word problems into each individual step and learn how to choose a familiar strategy.
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.
Solving One- and Two-Step Addition and Subtraction Problems
Students will use strategies to break down steps in a word problem, allowing for an understanding of the vocabulary and processes necessary, to apply correct math operations, maintain correct place value, and analyze solution feasibility.
No Interest If Paid in Full: How Much Do I Owe?
Students will write a linear equation from a real-world situation, identify the components of the equation, and interpret their meanings in the problem’s context.

Which One Doesn't Belong? Proportional vs Non-Proportional Relationships
Students will make connections as they examine proportional and non-proportional relationships represented in functions including tables, equations, graphs, and verbal descriptions and think critically to determine which one does not belong in a set and why.
Outside observers watching students working
Graphs and More Graphs Oh My!
Students will gather data based on a game and create the four types of graphs (pictograph, frequency table, bar graph, and dot plot).
Students Working
Can We Get There?
Students will calculate the rate of change and y-intercept from a real-world problem represented in a graph, a table, and/or an equation. They will then display and present their findings to the class.
