Zoos, Aquariums, and Expanding Students’ Data Literacy
Jan Mokros, Tracey Wright
Zoo and aquarium educators are increasingly providing educationally rigorous programs that connect their animal collections with curriculum standards in mathematics as well as science. Partnering with zoos and aquariums is a powerful way for teachers to provide students with more opportunities to observe, collect, and analyze scientific data. This article outlines step-by-step data activities for the classroom and field trips and for demonstrating important connections between mathematics and science. 

Using the Mathematics We Do Every Day
Mindy Kalchman
Kalchman describes and discusses preservice teachers’ changing views of what it means to know and do mathematics both inside and outside the classroom walls. The context for change is a weekly assignment for methods students to describe and solve mathematical problems in situations that they confront in day-to-day life. 

Math Fair: Focus on Fractions
Neelima Mokashi
The journey of a rewarding experience of creating mathematical environments for kindergarten and elementary students by focusing on one of the most important and often difficult-to-grasp concepts (fractions) through play methods.

Fraction Photo Frenzy: A New Exploration
Daniel Canada
When a class of preservice elementary teachers used SMART Board™ technology to expand their opportunities for sharing their thinking in a problem-solving environment that included the use of fractions, they found some exciting possibilities for sharing mathematical reasoning in elementary classrooms. 

Learning to Share Equally
Drew Polly, Laura Ruble
A lesson where third-grade students wrote a story problem for the task 10 ÷ 5. The authors share student work samples,  details about their misconceptions, and teachers’ modifications.
