Young children's exposure to early math concepts is important in their development, in their confidence in math skills, and in their ability to use math later in life. In 2013, the Heising-Simons Foundation embarked on an innovative path to support children's early math development. The Foundation invited several family engagement providers to…

The overarching purpose of this document is to define a new vision for mathematics instruction that explicitly attends to the needs of English Language Learners (ELLs), addressing the interdependence of language and mathematics. The sections in this report are devoted to (1) making clear that the grade-level college- and career-readiness…

This article describes a technique which uses a number line and simple games to teach primary-graders the relative value of different coins. (SJL)

This book is a collection of activities designed to complement an Algebra I program that features cooperative learning. The activity descriptions contain learning outcomes, the National Council of Teachers of Mathematics (NCTM) standards addressed in the activity, a suggested time frame for the activity, assessment opportunities, materials…

Describes a strategy to make chi-square calculations and interpretations more understandable by presenting the theory behind the test to the students in a visual manner. Involves using dihybrid corn to generate a large sample of chi-squares followed by plotting a frequency distribution to get at the meaning behind the chi-square table. (JRH)

Suggests mathematics readiness activities that teachers and parents can use with preschoolers: comparing shapes and sizes; counting; and learning quantitative concepts such as "less" and "more." (SJL)

Writing is a key component in developing mathematics thinking and understanding. Four strategies to encourage student writing to describe thinking and reasoning are offered. Teachers can use this writing to verify student understanding of mathematical concepts. (MT)

Offers historical information about square roots. Presents three different methods--Hero's method, visual method, and remainder method--which can be used to teach the finding of square roots and one method for determining cube roots. (ASK)

It is important for young children to see the connection between the math they learn in school and everyday situations. Uses games, songs, cooking experiences, movement activities and arts and crafts projects to illustrate the connection. (Author/RK)

Eleven teaching aids designed to help primary students master basic mathematics concepts. (CM)

The theorem is seen as the foundation for large-sample statistical inferences, and is usually difficult for students to understand because one expects to take only one sample from a population. A description of how a table of random numbers readily available to students could be used is provided. (MP)

Teaching suggestions for graphing the function y=sin 1/x and the greatest integer function are given. (MK)

An activity for generating approximations of pi is described. (MK)

A way that allows students to discover a strategy for determining the area of rectangles, squares, parallelograms, triangles, and trapezoids is described. Students use grid paper and scissors to determine the number of square units that cover a specified space. (KR)

Describes teaching about proofs in college-level mathematics courses. Presents typical questions that students raise while studying proofs and offers possible answers to these questions. (ASK)
