  1. 1. Mathematical Process of the Month: Connections CN Learning in all subjects is predicated on making connections between newUnderstanding Mathematical concepts and existing schema; that is, mental images and ideas, or what the learnerProcess StandardsSuccessful learning in mathematics is already knows. Powerful learning draws on the learners’ experiences and life context.achieved through “relational Students with extensive life experience have more pre-existing schema to createunderstanding”. A conceptual connections with new concepts. This is called “crystalized intelligence”, as opposedunderstanding of math builds on to “fluid intelligence”, which is the natural ability we are born with. Interestingly,humans’ natural desire to make senseof things. It helps learners acquire crystalized intelligence is a greater predictor of student success. This is good news fornew knowledge and apply it in learners, because while fluid intelligence is innate, crystalized intelligence can beunfamiliar situations. Conceptual controlled. Educators capitalize on this by arranging experiences for students throughunderstanding improves students’attitudes toward math because they field trips, interactive learning experiences, projects, and inquiry. Everything acan see math as an accessible subject student has learned in the past becomes the hook on which to hang newthat can be understood. Effective information. As math educators we are very familiar with this analogy, as we knowmathematics instruction incorporatesseven process to ensure that students that math concepts build on each other through the years.develop a conceptual understanding There are several types of connections that are important to learningof math: Communication, mathematical concepts:Connections, Mental Math and Connecting ideas within mathematics. Our curriculum helps us do this byEstimation, Problem Solving,Reasoning, Technology and organizing mathematical themes which are evident in the strands of the curriculum.Visualization. Beside the Outcomes These themes tie mathematical topics together so the student can realize generalin the curriculum document are principles at work and how they are related. Students will encounter these big ideassuggestions for which of theprocesses lend themselves well to the repeatedly and in many different contexts as they develop depth of understandingteaching of that outcome; however, through the grade levels. As educators, we need to ensure that we highlight theseall processes are interrelated and are related concepts to help students build on and expand their prior learning;part of the everyday business in theclassroom. They are the media otherwise, math is perceived as fragmented and compartmentalized. Learning isthrough which we deliver content. through memorization which is low-level and not lasting. Our first job as educators is to become very familiar with the curriculum, especially at our own level but alsoConnections: Because the through the years so that we can understand ideas that are nested within each other,learner is constantly searching and concepts that are threaded and integrated.

A teacher’s task is to illuminate the relations between thecomplex and concrete known and the new.

In the same way that mathwhich we tie new concepts classrooms draw on literacy and social skills, so should other disciplines require students to apply mathematical reasoning and value mathematical literacy. Connections between symbols and procedures in math. Part of our work in establishing mathematically literate students is helping them gain an understanding of the representations of mathematical ideas. Students must be actively engaged in the work of mathematics to be immersed in the language of math. Word walls and front-loading vocabulary are strategies to assist with connecting to the language of mathematics, as are Frayer models, carrol diagrams, and other concept attainment activities and graphical representations. Teachers promote mathematical literacy by introducing many representations, modelling different approaches, and arranging opportunities for students to compare, explore, reason with and talk about mathematical approaches and representations.

  3. 3. Formative Assessment Feature Frayer Model: Like many strategies that may be introduced as “formative assessments”, The Frayer model (one example is shown at left) is not only useful for formative assessment but also as a routine instructional practice. It has been described as a concept map, graphic organizer, and vocabulary development tool. It can be used to introduce topics or concepts, front load vocabulary, or check for understanding. It can also be used for clarifying mathematical symbols. The Frayer model helps students make sense of words or concepts, and connect them to pre-existing understandings. It requires critical thinking to establish deeper understanding, and it creates a visual reference for concepts and vocabulary. Students can work on a Frayer model individually, in pairs, or collaboratively in groups. You could have students include pictures to help make connections with the concept. After making Frayer models have students examine each other’s work, compare and discuss. Frayer models have more to them than meets the eye! Customizable, Downloadable Frayer Model Templates are available here: http://www.worksheetworks.com/miscellanea/ graphic-organizers/frayer.html Shown at left is a table of instructional practices (Marzano) that are shown to have significant impacts on student learning. The Frayer model incorporates several of these! “Contextualizing and making connections to the experiences of learners are powerful processes in developing mathematical understanding. When mathematical ideas are connected to each other or to real-world phenomenon, students can begin to view mathematics as useful, relevant, and integrated.” –WNCP 2006 K-W-L Chart: This is often used as a pre-assessment or entrance slip. A chart has three columns, where students record what they already know (K), what they want to know (W) and what they have learned (L). This can be done on a small piece of paper, for entrance slips, or on three separate poster papers for a more collaborative activity. This activity requires students to activate prior knowledge, and apply higher-order thinking strategies in order to construct meaning. Having students do this at the start of a lesson or unit can be a focussing activity, and having them repeat it at the end gives a visualization of learning and progress, which encourages motivation by creating an awareness ofA downloadable K-W-L Chart is available at achievement.http://www.educationworld.com/tools_templates/kwl_nov2002.doc
  4. 4. Relational Understanding: Instrumental Understanding:  Conceptually based  Rule based  Knowing both “how” and “why”  Knowing “how” but not “why”  Acquired by sense-making  Acquired by rote  Interconnected knowledge  Isolated knowledge  Easier to remember  Harder to remember  Involves fewer principles of more general  Involves a multiplicity of rules application  Inflexible, not readily adaptable to new tasks  Flexible, more adaptable to new tasks Cool Stuff to try: Have you heard of three-ring?
