Math Investigations

Our mathematics program takes an investigative approach, which helps students build conceptual understanding as they transition from the concrete to the representational to the abstract. Emphasis is placed on using mathematical process skills to solve practical problems in a variety of contexts throughout the year.

Our instructional program is built upon a framework for teaching, learning, and assessing in mathematics at all grade levels using the following mathematics process skills:

  • Problem solving: Students will apply a wide variety of mathematical concepts, processes, and skills to solve a broad range of problems in various content areas and everyday situations.
  • Reasoning and Proof: Student will apply mathematical reasoning skills to investigate, evaluate, justify, and connect approaches and solutions to situations in mathematics and in other disciplines.
  • Communication and Representations: Students will accurately and clearly present and justify mathematical ideas in diverse formats.
  • Connections: Students will develop the ability to use connections among mathematical ideas to build on one another when solving real-world problems and to interconnect ideas to produce an integrated coherent whole.

A special emphasis is placed on using math process skills to solve practical problems in a variety of contexts throughout the year.  The main content emphasis is on building:

  1. Number sensedeveloping an understanding of decimals, including the connections between fractions and decimals.
  2. Computational fluencyquick recall of multiplication facts and related division facts and fluency with whole number multiplication.
  3. Measurement sensedeveloping the skills and concepts of area and two-dimensional shapes.

Our content standards are all from the following strands of mathematics:

  • Numbers and Operations
  • Geometry and Measurement
  • Algebra
  • Data Analysis and Probability

It will at all times be stimulating to learn content material from other writers and practice a bit something from their store. I’d choose to use some with the content material on my blog whether you don’t mind. Natually I’ll offer you a link on your net blog. Thanks for sharing.
