In this logic activity, students must determine how to represent three quantities using a fixed amount of space (Venn diagram) and objects. The goal is to represent the siblings’ ages, 5,6, and 7, using only ten plants. This resource includes teacher notes with extension suggestions and possible support options.

This interactive applet reinforces students' knowledge of the properties of rectangles and gives them a game in which to form and test hypotheses. In a 5x5 grid in which a rectangle has been hidden, students try to fix the location with the fewest number of probes (Note: press 'Start' to hide a different rectangle). Ideas for implementation, extension and support are included along with printable sheets and video clips of classroom testing.

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 page of the Big 6 website is a pdf version of a PowerPoint presentation about note-taking.

Precalculus is adaptable and designed to fit the needs of a variety of precalculus courses. It is a comprehensive text that covers more ground than a typical one- or two-semester college-level precalculus course. The content is organized by clearly-defined learning objectives, and includes worked examples that demonstrate problem-solving approaches in an accessible way.

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 for secondary students focused on teaching them to participate as U.S. citizens.

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 helps students evaluate print resources using the Big6 and the CAARS models.

In this NRICH article the authors discuss the definition of problem solving and the three ways the topic can be considered in the classroom: teaching for problem solving, teaching about problem solving and teaching through problem solving. Using examples from the NRICH site, the authors elaborates on each of the three ways that teachers can think about problem solving. The article can be printed in rich text format.

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 a presentation about digital research and information literacy.

In this problem students apply basic proportional reasoning in the context of a pie recipe. Given a recipe for 80 pies, Peter needs to determine whether the ingredients he has on hand are enough to make 2 pies. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, ideas for extension, and printable lists of ingredients (doc).

This activity gives students a chance to visualize a two-dimensional net of a three-dimensional object. Students are shown three views of a decorated cube and a net of six plain squares. They must decorate the net so that it folds to a cube consistent with the views. An interactive applet is provided. Ideas for implementation, extension and support are included along with three printable sheets (pdf).

Quin Henderson, Partnerships Manager of Future Design School, joins Homeroom today to share his thoughts on the importance of design thinking in our classrooms. Included in our conversation is the need for teachers and students to innovate, how problem solving is an essential art in learning, and the need to build creativity into our schools.
