The Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010) define what children should understand and be able to do in K-grade 12. This document also includes a description of key mathematical processes and proficiencies, the Standards for Mathematical Practice (SMPs), which provide an important overview for the kind of robust thinking…

Because fractions and percentages can be difficult for children to grasp, connecting them whenever possible is beneficial. Linking them can foster representational fluency as children simultaneously see the part-whole relationship expressed numerically (as a fraction and as a percentage) and visually (as a pie chart). NCTM advocates these…

David Schwartz's classic book "How Much Is a Million?" can be the catalyst for sparking many interesting mathematical investigations. This article describes five episodes in which children in grades 2-5 all heard this familiar story read aloud to them. At each grade level, they were encouraged to think of their own way to explore the concept of…

Problem solving lies at the heart of mathematical learning. Children need opportunities to write, discuss, and solve problems on a regular basis. The problems must incorporate grade-appropriate content and be "accessible and engaging to the students, building on what they know and can do." Teachers also play a key role in establishing a classroom…

This article describes some benefits of using problem posing in the classroom, and provides suggestions to teachers for how to begin implementing this strategy.

Students can be provided opportunities to build both English and mathematical proficiency through reading, discussing and extending mathematics-related books. The experience of a teacher through which she expanded her instructional use of mathematics-related literature is described, which was equally valuable for English Language Learners and…

Describes how using the familiar "Magic Triangle" puzzle with a class of 4th grade students contributed to the development of a supportive mathematical community. (Author/NB)

Describes how a children's book on counting was used in integrated mathematics-literature lessons in first-grade classrooms and how students created their own texts. (11 references) (MKR)
