Eric.ed.gov – Simple Fractions. Math in Action. Workbook.

eric.ed.gov har udgivet: This workbook is designed as an easy-to-read, slower-paced mathematics text for students who have learning, reading, and language problems. Helping students fulfill mathematics requirements for graduation is a goal; the book can be used as the core or supplement to the mathematics curriculum in mainstreamed or special education classrooms, in mathematics laboratories, or as part of sheltered workshop and vocational training programs. The eight units begin with a brief discussion of how fractions are used in real life. Each lesson focuses on only one major concept, and includes comprehension exercises with an answer key. Most lessons are reinforced with at least one worksheet, available in the teacher’s guide. The units are titled: Fractions All Around You, Naming Fractions, Different Names for the Same Amount, Renaming Fractions, Comparing… Continue Reading

tandfonline.com – Is counting hindering learning? An investigation into children’s proficiency with simple addition and their flexibility with mental computation strategies

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT There is a growing awareness that many children are not developing fast and accurate retrieval-based strategies for solving single-digit addition problems. In this study we individually assessed 166 third and fourth grade children to identify a group of children (called accurate-min-counters) who frequently solved simple single-digit addition problems using a min-counting strategy and were accurate using it. We investigated if these children were adaptive when it came to using retrieval for simple addition and if they were disadvantaged when it came to demonstrating mental computational flexibility with multi-digit addition. We found accurate-min-counters represented over 30% of participants. These children were often incorrect when they were required to use retrieval for simple addition and were less flexible than most… Continue Reading
