###
Word problems, models and more!

**The students will engage in group activities to solve word problems with and without models as well as writing equations. **

###
Newton's Second Law

Students will work in partners to investigate Newton’s second law by testing a series of experiments with varying conditions.

###
Crime Scene Two Steppers: Two-step word problems using multiplication and division

Students will collaboratively solve two-step real-world word multiplication and division problems by using a checklist. Students will also solve a two-step word problem by completing a hands-on group activity.

###
Equations in the Real World

**Students will create and solve equations with variables on one side before comparing the equation with another to determine at what rate they will be equal. **

###
Colorful Fractions

**Students will represent fractions in multiple ways, such as pattern blocks, fraction strips, and number lines.**

###
How Newton's Laws Apply Every Day

Students collaboratively determine how the characteristics of a real-world job correlate with each of Newton’s Laws and why that is relevant to their own lives.

###
The Great Classroom Escape

Students will work collaboratively to solve six real-world multiplication problems and earn puzzle pieces they can put together to reveal a phone number they can call to escape the classroom.

###
Rise Over Run! Let’s Have Fun!

Students will collaboratively practice identifying and graphing slope and y-intercept.

###
Who Ate More - Fractions on a Number Line

In this activity, students will consider a real-world scenario requiring them to compare two fractional amounts using a number line. Through the use of the number line and peer collaboration, students will recognize equivalency in the two fractional quantities and effectively communicate their understanding of this concept.

###
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.

###
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. **

###
What Goes In, Must Come Out

**Students will learn how to use an input-output table using real-world examples.**

###
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.

###
Convergent Plate Boundaries

Students will design and test models that will identify crustal features formed by convergent plate boundaries.

###
Full Speed Ahead

Students will use hover pucks to measure speed over a distance of six meters. Once speed has been calculated, students will determine velocity using the same data. Finally, students will be able to label all points of acceleration.

###
Models of Multiplication

Students will solve one-step multiplication problems using various multiplication strategies such as objects, pictorial models, arrays, equal groups, repeated addition, and number lines.

###
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.

###
Push Back, Pull Forward

Students will conduct an experiment to demonstrate force such as pushes and pulls.

###
Four Representations of Linear Relationships

Given one representation of a linear relationship, students will create a poster displaying the other three representations of linear relationships.

###
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.
