13 Rules That Expire

This 8-page article from Teaching Children Mathematics discusses how overgeneralizing commonly accepted practices, using imprecise vocabulary, and relying on tips and tricks that do not promote conceptual mathematical understanding can lead to misunderstanding later in students’ math careers. The authors provide a table of some "expired" mathematical language and suggest more appropriate alternatives.

This resource is included in the following PD Collection(s):
CCSS Practice Standard 6Common Core’s Mathematical Practice 6, Attend to Precision, calls for students to be clear in their reasoning, calculation, and communication through the precise use of words, symbols, units of measure, mathematical expressions, and processes. Students recognize various levels of precision and apply them appropriately; they calculate accurately and efficiently. These resources are intended to help teachers and math specialists understand the intent and scope of MP 6 and plan for successful attainment in the classroom. A companion Classroom collection, Implementing CCSS Practice Standard 6, includes resources to help teachers foster this practice with their students.

      Focusing on Concepts rather than Rules
      By bethb on 09/03/2014 - 15:13
    • This article reinforces the idea of focusing on concepts rather than rules. When teachers focus too much on rules children get frustrated because they don't know why they are doing what they are doing and therefore don't "get it" when "rules change".

      It might sound trivial, but

    • It might sound trivial, but your cheap christian louboutin footwear can actually make or break your look. Wearing the wrong style or size of footwear can make you look much older than your actual age. Make sure your shoes are never mismatched with your outfit. Heels always add to your style and make you look younger and slimmer than you are. If not heels, make sure the flat footwear you choose is very stylish. Wearing running shoes or flip-flops with cheap football shirts can make you look older, and a fashion disaster too! Dark-rimmed glasses are certainly a stylish statement piece, but only with the right look and the right outfit; not with your sarees, kurtis and gowns! With certain outfits like trendy casual wear, football shirts sale, and even some dresses, they look peppy. But if you wear dark-rimmed glasses for a friend's wedding or a puja, you might look 10 years older than what you are! If you really want to wear them, choose a rimless or light-rimmed frame, or go for contact ray ban replica lenses.
