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.

###
Centers in Subtraction

**Students will participate in multiple centers including a guided math center that reinforces subtraction concepts. **

###
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. **

###
More Super Duper Math

**Students will gather objects to compare quantities and justify their answers pictorially and verbally. They will use their vocabulary posters and accountable talk menus to discuss with their partners. **

###
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.

###
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.

###
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.

###
Planting the Seeds of Perimeter

**Students will create planters that meet specific perimeter dimensions. The students will need to determine the number of sides and the perimeter for their planter. **

###
Utilize Strip Diagrams to Solve Multi-step Multiplication and Division Word Problems

Students will utilize manipulatives to create concrete and pictorial strip diagram representations in order to solve multi-step multiplication and division word problems.

###
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 equa l 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.**

###
The Picture Graph Party

Students will explore and create picture graphs through collaboration and group work.

###
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.

###
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.
