We introduce the Into Math Graph tool, which students use to graph how “into" mathematics they are over time. Using this tool can help teachers foster conversations with students and design experiences that focus on engagement from the student’s perspective.

## Student Engagement with the “Into Math Graph" Tool

### Amanda K. Riske, Catherine E. Cullicott, Amanda Mohammad Mirzaei, Amanda Jansen, and James Middleton

## Let's Hit the Target!

### Manouchehri Azita, Ozturk Ayse, and Sanjari Azin

In this article we illustrate how one teacher used PhET cannonball simulation as an instructional tool to improve students' algebraic reasoning in a fifth grade classroom. Three instructional phases effective to implementation of simulation included: Free play, Structured inquiry and, Synthesizing ideas.

## Using Scratch Programming to Explore Coordinates

### Erell Germia and Nicole Panorkou

We present a Scratch task we designed and implemented for teaching and learning coordinates in a dynamic and engaging way. We use the 5Es framework to describe the students' interactions with the task and offer suggestions of how other teachers may adopt it to successfully implement Scratch tasks.

## Technology Continues to Evolve

Over the past 100 years, technology has evolved in unprecedented fashion. Calculators, computers, and smart phones have become ubiquitous, yet school mathematics experiences for many children still remain without many powerful technological tools for the exploration of mathematics. We consider the evolution of some tools as we imagine a future.

## Triangle Center Technology

### Anne Quinn

The paper discusses technology that can help students master four triangle centers -- circumcenter, incenter, orthocenter, and centroid. The technologies are a collection of web-based apps and dynamic geometry software. Through use of these technologies, multiple examples can be considered, which can lead students to generalizations about triangle centers.

### Leigh Haltiwanger, Robert M. Horton, and Brooke Lance

Making mathematics meaningful is a challenge that all math teachers endeavor to meet. As math teachers, we spend countless hours crafting problems that will energize students and help them connect mathematical topics to their everyday lives. Being successful in our efforts requires that we allow students to explore ideas before we provide explanations and demands that we ask questions to promote a depth of thinking and reasoning that would not occur without such probing (Marshall and Horton 2009).

## Using Aviation to Change Math Attitudes

### Jerra Wood

A flight simulator presents a new STEM slant on students' knowledge of linear equations.

## Exploring Slope with Stairs & Steps

### Toni M. Smith, Padmanabhan Seshaiyer, Nathalia Peixoto, Jennifer M. Suh, Graham Bagshaw, and Laurena K. Collins

Two activities help develop students' understandings of rate of change and slope within STEM contexts.

## Robots Bring Math-Powered Ideas to Life

### Kasi C. Allen

A compelling contest motivates students and makes mathematics and STEM relevant.

## A Geometric Path to the Concept of Function

### Scott Steketee and Daniel Scher

Transformations using dynamic software can provide a unique perspective on a common topic.
