This list of questions is now complete. The questions cover all the papers we read in our Fall 2014 mathematics education research seminar. I have discovered that having a list of specific reading questions available for when there is a "lull" in the conversation or for when the conversation gets "off track" is useful for refocusing the discussion in a useful direction.

This is a list of the papers, with discussion questions, that we are reading and discussing in our math ed research seminar this semester. I find it useful to have such questions prepared ahead of time in case there is a "lull" in the conversation, or if the conversation goes in unfruitful directions, so it can be redirected to discussing the paper at hand.

For the past 2 years, Mrs. Perez, a third-grade teacher, and Mr. Williams, a special education teacher, have co-taught a diverse class of 22 students, including 10 students with disabilities. Although they enjoy their collaborative relationship, Mrs. Perez, an 11-year veteran, would prefer to spend her day teaching reading and early writing instruction; similarly, Mr. William's love for reading and his desire to support students who struggle with reading and writing skill development motivated him to become a special education teacher. Although neither dislikes mathematics, it does not come as naturally to them. Mrs. Perez also feels a great deal of anxiety from the pressure of state assessments in a content area that had been a struggle for her as a learner. It is not surprising that for guidance they both cling to the district-adopted mathematics textbook and its supporting resources. The "toolbox" of resources Mr. Williams has collected and developed over the years for teaching reading, combined with Mrs. Perez's own reading strategies treasure trove, could serve as an accredited series independent of district resources. However, in mathematics, their concern about the content limits them to the core textbook and two resources suggested for struggling learners. Having nearly completed a second year together, they are increasingly concerned about what they are not doing, what the textbook does not provide, and their need for additional supports and solutions to help them truly meet the needs of their 22 students, especially those with disabilities.

Math Expressions ®

Build deep understanding with this essential inquiry-based mathematics curriculum.

Mastering math starts with knowing the numbers. We get students started on the right path in Pre-K, but that's just the beginning. It’s also about looking beyond numbers to understand how and why they work, and learning to ask the questions that lead to a thoughtful, informed approach to solving problems.

Based on research funded by the National Science Foundation (NSF), Math Expressions is a proven Pre-K–6 curriculum that helps children make sense of math by exploring, discussing, and demonstrating their understanding of key concepts. In busy, active lessons, students learn how to look deeper and choose their own path to the answers—skills that will take them far beyond the math classroom.

Every lesson integrates mathematical processes and practices.

Realworld Icon Mx Wf285498

Schools see an average gain of 12–15% on state tests.

Looking deeper produces exceptional results.

When children understand math, they’re not relying on memorization. They’re relying on themselves. Dr. Karen Fuson’s comprehensively researched approach to teaching math is based on the way children actually learn and is used across the country because it raises student achievement.

A yearlong study of success

Students from eight schools across four states showed “statistically significant” improvement.

See what Math Expressions has in store for your classroom.

How to think about math.

The deep conceptual understanding that’s the hallmark of the program leads to strong skills fluency and the ability to make generalizations within and among mathematical strands. As students grow and learn to think critically, teachers develop their own richer understanding of math through detailed instruction and embedded support.

Math Expressions is based on NSF-funded research.

  • Contextual Learning Students develop an understanding of mathematics through real-world situations and visual supports.
  • Multiple Strategies Students learn multiple ways to solve problems, including algorithms based on reasoning.
  • Manageable Instruction Teaching materials embody a "learn-while-teaching" style.

Making teachers' lives easier by changing the learning landscape

Hear what Dr. Fuson thinks about early learning in mathematics and how it can help close the equity gap.

Research tells us that students who start kindergarten with a high level of math understanding do better in both math and reading after kindergarten. With that in mind, we developed Math Expressions Early Learning Resources to provide early learners with the understanding they need to confidently take the first and subsequent steps of their mathematics journey.

  • Grounded in Research Students will benefit from teaching-learning paths and structured, repetitive experiences as recommended in “Mathematics Learning in Early Childhood: Paths toward Excellence and Equity.”
  • Rated as Strong by ESSA Early Learning Resources is based on the same ESSA strong foundation and research as the rest of Math Expressions , making it an ideal transitional program for pre-kindergarten early learners.
  • Focused on Numbers and Geometry Research guidelines led to a strong focus on numbers and geometry, content areas that are particularly important in early math instruction.
  • Hands-On Playful activities help children see, discuss, and use mathematical structures, building understanding and fluency gradually and systematically.
