**Title:** Multiplication My Way

**Description:**
In this lesson, students will explore the US Algorithm Method of multiplication using a unique way of describing it known as the Turtlehead Method. Students will collaboratively work together to complete story problems using the US Algorithm Method of multiplication to solve two-digit by two-digit multiplication problems.
**Standard(s): **

[TC2] (3-5) 2: Use various technology applications, including word processing and multimedia software.

**Subject:**Mathematics (4 - 5), or Technology Education (3 - 5)

**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.
