This article explorees reading for information using the "Trash-N-Treasure" method of teaching note-taking.

This activity gives students an opportunity to use and develop their visualizing skills in conjunction with the knowledge of fractions. Students are given one large rectangle that is divided into ten smaller quadrilaterals and triangles in which they have to find what fractional part is represented by each of the ten numbered shapes. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support.

In this problem students use spatial awareness and visualization to solve problems related to reflection (bilateral) symmetry. Learners are given three shapes and must assemble as many different but symmetrical composites as possible. Ideas for implementation, extension and support are included along with printable sheets of the shapes and a poster.

This interactive Flash applet gives students the opportunity to copy, create and extend repeating patterns utilizing two different triangles. Many patterns are possible since the angles in both are multiples of 30 degrees and the shorter sides are equal in length. The Teachers' Notes page includes suggestions for implementation, ideas for extension and support, and printable sheets (pdf).

The Big6 is a six-stage model to help anyone solve problems or make decisions by using information. Students can use this model to guide them through the research process. This resource is an editable research project organizer for grades 7-12.

The Big6 is a six-stage model to help anyone solve problems or make decisions by using information. Students can use this model to guide them through the research process. This resource describes a Big6 lesson focused on research questions which call for more than information gathering.

This activity challenges students to visualize compound transformations of hexahedral dice to determine their right- or left-handedness. Ideas for implementation and support are included along with printable sheets of both types of dice.

This problem allows students an opportunity to think about fraction comparisons and equivalencies in a different way using interactive rods. Students are given two different fraction rods of unknown lengths and the goal is to find out what fraction the shorter rod is of the longer rod. A Teacher's Notes page, hints, solution, and printable pages are provided.

This activity builds student knowledge of ratios by using Cuisenaire rods to determine proportion and form equivalent ratios. Students may use the Cuisenaire rod environment embedded in this resource or they may use actual Cuisenaire rods depending on preference/ability/accessibility. This resource includes teacher notes, solution, and suggestions for questioning.

The Big6 is a six-stage model to help anyone solve problems or make decisions by using information. Students can use this model to guide them through the research process. This resource is an assessment tool to meausre student progress in each Big6 skill area.

This activity uses Cuisenaire Rods to develop conceptual understanding of factors and multiples and to encourage systematic thinking. Users are shown a train of four different rods and asked to find equivalent trains, each made from rods of just one color. An interactive Flash Cuisenaire applet is provided as an alternative to using real rods. The Teachers' Notes page offers suggestions for implementation, discussion questions, and ideas for extension and support.

This problem challenges and extends students' spatial awareness with 2D shapes. The students are given three different irregular shapes. The goal is to divide each of them into two parts that are exactly the same shape and size. The Teachers' Notes page offers rationale, suggestions for implementation with a link to Happy Halving (cataloged seperately), discussion questions, and ideas for extension and support.

The Big6 is a six-stage model to help anyone solve problems or make decisions by using information. Students can use this model to guide them through the research process. This resource guides students through writing a science lab report.

This brief article describes the historical contexts in which two types of cipher (code), the shift and the substitution cipher were used. The math concepts involved are substitution, inverse operations and letter frequency analysis.

This open-ended investigation provides an opportunity for students to develop problem solving skills and explore patterns while applying number skills. Posed in the context of friends sending each other cards, it asks students to find how many cards are sent based on the number of friends, and to look for patterns that emerge in the results. The Teachers' Resources page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support. Be sure to check out the Solutions page to appreciate the potential range of student thinking.
