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 Shapes Around Us

Students will make connections between real-world objects and the attributes of two-dimensional shapes.

###
Centers in Subtraction

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

###
The Picture Graph Party

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

###
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 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.
