**Title:** Explorations in Place Value

**Description:**
Explorations in Place Value is an interactive math mini-unit that incorporates the use of children’s literature, mathematical learning stations, and small group instructional strategies to reinforce basic principles of place value and to teach students about writing large numbers in expanded notation.
This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.
**Standard(s): **

[MA2015] (4) 7: Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons. [4-NBT2]

**Title:** "Hanging Out the Laundry" with Place Value

**Description:**
As an introduction to the thousands place in place value, students will first practice with place value mats and base ten blocks. Then students will play "hanging out the laundry" for more practice with place value. Additional practice can be gained by accessing the website provided.

**Title:** The Variable Machine

**Description:**
This Illuminations lesson provides an introduction to the use of variables. Students explore the idea of variable as a symbol that can stand for any member of a set of numbers, and they substitute numbers for variables (letters) to discover unknown values.
**Standard(s): **

[MA2015] (5) 6: Read, write, and compare decimals to thousandths. [5-NBT3]

**Title:** Further Investigating Greater Than, Less Than, and Equal To

**Description:**
Students build upon their understanding of greater than, less than, and equal to by observing quantity and making comparison using varied instructional materials. The fish cut-out, with its mouth open, represents the greater than or less than symbol; the clam cut-out represents the equal to symbol. Using fish lips as a transition point, children will apply their understanding of greater, less, and equal to the standard symbols as the teacher introduces symbolic notation at an developmentally appropriate level.

**Title:** Communicating about Mathematics Using Games: Playing Fraction Tracks

**Description:**
Mathematical games can foster mathematical communication as students explain and justify their moves to one another. In addition, games can motivate students and engage them in thinking about and applying concepts and skills. This e-example from Illuminations contains an interactive version of a game that can be used in the grades 3-5 classroom to support students' learning about fractions. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.
