# Collections

Classroom collections are ideal for teachers to use in helping students understand concepts. Each resource set includes an outstanding selection of interactives, games, videos and learning tools.
This collection of resources helps students develop geometric thinking about shape and space in mathematical and real-world contexts. Students will gain knowledge and rich conceptual understandings of two- and three-dimensional shapes, patterns, transformations, symmetry, and visualization. Learning resources include interactive media, videos and games for both primary and upper elementary grades.
This collection has lesson plans and interactive whiteboard tools for teaching equivalent fractions. There are also games and interactive activities in which students create and use various models associated with fractions. Some resources provide students with practice in renaming and simplifying. After a few directions or demonstrations, students will be able to use many of these activities independently.
This collection of resources includes tools that teachers can use when introducing and modeling operations with fractions. These handy tools can be used for whiteboard demonstrations and some also provide students with opportunities to manipulate the models. Additional resources include solving word problems with fractions and estimation using benchmark fractions.
Use the resources in this collection to encourage your students to talk about the math they use to play the game or solve the problem. Encourage them to share their thoughts and describe their strategies to one another as they figure out the best moves or steps in a process. Provide students with opportunities to demonstrate their work and explain their reasoning using the language of mathematics. Listen carefully as your students interact with one another to exchange ideas, organize their thoughts, present their arguments and consider the suggestions of their classmates. These resources provide you with starting points that engage students in mathematical thinking and communication.
This collection has tools that teachers can use in the classroom, on individual computers or with an interactive white board. You'll find virtual Cuisenaire rods, base ten blocks, pattern blocks, and thinking blocks for whole numbers and for fractions, and an interactive hundreds chart. There are two virtual geoboards, a coordinate one and an isometric one. Two tools enable you or your students to create various types of graphs, and the dynamic paper tool allows you to custom create many types of graph paper for use in your classroom. There are also interactive coordinate graphs.
This collection of resources will help teachers to find interesting and challenging problems that engage students in learning new concepts and developing new stategies. Several teacher packets from the Math Forum @ Drexel University provide a sample problem and all of the information you need to use it with your classes. The other sources include access to a variety of problems appropriate for elementary level children and offer suggestions about how to use them with your students.
