Describes first grade students' mathematical investigation of the number of spots on a cheetah. The exploration of counting and estimation strategies that grew from the investigation gives evidence that mathematicians come in all ages. (ASK)

Presents five mathematics activities to celebrate the 100th Day of School. Lists the full set of activities that relate to mathematics, art, music, physical education, science, social studies and history, English, and creative writing. (ASK)

Having children create and solve their own story problems is a valuable activity to use for them to think carefully about and apply a concept to create and solve a problem. Describes using two books to help children learn about the concept of multiplication. (ASK)

Describes and shares one incident of a teacher's mathematics exploration in a professional development setting to exemplify the ideas of the Professional Standards for Teaching Mathematics. Focuses on the handshake problem which tries to find out how many handshakes will occur if 20 people shake hands with every other person. (ASK)

Describes a mathematics lesson using digital sums that allows teachers to assess third grade students' understanding of reasoning, arithmetic, and geometry. (ASK)

Describes how classification came alive in a third grade classroom as children searched for rules or properties defining the five Platonic solids, then constructed a precise definition to classify these solids. (ASK)

Explores the phenomenon of math anxiety in a group of elementary school students by observing and conducting a survey to identify where students fit into the continuum of mathematics confidence. Discusses strategies to reduce math anxiety. (ASK)

Offers ideas for helping parents do mathematics with their children as part of everyday family life in ways that are consistent with the National Council Teachers of Mathematics (NCTM) Standards. (Contains 11 references.) (ASK)
