This activity allows the user to estimate quantities and sizes including the number of objects in a set, the lengths of a curve, and the area of a shape. Many options are available for exploration - the size of the curve can be changed, problem type can be changed and there are 2 levels of difficulties. The learner section explains the activity as well as discusses how estimation is used in everyday life. In addition to a description of the activity, the instruction section provides possible issues to address in the classroom, links to standards, and links to other similar resources.

tag(s): estimation (47), measurement (179)

#### In the Classroom

Introduce the activity on the interactive whiteboard or projector and model for students how to use estimation instead of actually counting the figures. Use the site as a springboard to discuss when estimation is appropriate and when measurement is needed. Use the site to begin discussions on what level of estimation is needed in different circumstances (close, really close and almost perfect).

Lego Education Activities are designed to be rich, fun-filled, creative learning experiences. They offer educators a means to use LEGO sets as essential tools that engage students while challenging their creativity and enhancing their knowledge and comprehension. As a thinking teacher, you only need to look on the Teachersfirst Editor's Blog here to realize what a hot topic teaching creativity is and how it fits into the classroom. From role-playing and meeting the needs of early childhood development to theme-based sets for older students, LEGO Activities offer a multi-disciplinary approach to teaching. There are also specific sets designed to cover specific subject areas, including technology curriculum. As you browse the activities, you will find obvious connections to curriculum in simple machines and other science topics, as well. Stay current and find a lot more stimulating ideas by checking out the LEGO Education and LEGO Smart Blogs available from theLego Education Activities page.

tag(s): creativity (120), critical thinking (116), logic (246), problem solving (292)

#### In the Classroom

Expose your students to different levels of the learning spiral by challenging them to use problem-solving skills for increasingly difficult obstacles. Students can work in small groups to foster cooperation and teamwork as they sort, graph, follow and give directions, and discuss ideas. Of course you will need some LEGOs, so you might try raiding your own children's toy boxes, include a request in your classroom newsletter for donations, look around for LEGO kits collecting dust on classroom shelves, or put it on your school's PTA wish list. Be sure to have cooperative learning groups video their activities to share with the rest of the class using a site such as SchoolTube (reviewed here).

Great for a foundations of science class or middle level environmental science class, use this activity to have students "get their hands dirty" solving real life problems with real life activities. Life After Trash is an excellent lesson for having students think beyond the obvious uses of everyday products. Concepts such as landfills, the three R's (reduce, reuse, and recycle), and basic environmental awareness are partnered with the skills of working in groups, critical thinking, and problem solving to create an interesting and fun classroom activity. There is little cost (if any) to doing the lab.

tag(s): critical thinking (116), engineering (133), problem solving (292)

#### In the Classroom

A week or so before conducting this simulation activity, ask students to bring in recyclables and clean trash from home. This will cut down on the amount of trash you need to collect, and it will add variety to the supplies. Set up the activity by talking about trash, where it comes from and where it goes. Discuss better alternatives for trash "disposal" such as recycling and reusing. Have students think of obvious reuses for materials and then explain that there are other alternatives to obvious uses. Introduce the activity and basic rules and safety to the students. Arrange them in groups of three or four and then allow them to "shop" the classroom "landfill" to create new things out of old trash. Follow up with discussion of group products, uses, and real life applications of this idea such as recycled art.
