Precision School Balance

Your Precision School Balance (LER 2420) will help students explore, develop, and extend their understanding of mathematical and scientific concepts including inequalities, mass, comparisons, the four operations, and order. The Precision School Balance comes with a 10-piece gram set including two 1-gram masses, two 2-gram masses, two 5-gram masses, two 10-gram masses, one 20-gram mass, one 50-gram mass.

Balance Components

Your Precision School Balance has many features that make it simple for students to use. It is also accurate enough to use for precise measurements.

•The damping button helps make quick and accurate measurements. The button steadies the swing arm and prevents the pans from rocking during a measurement.

•The calibration slider allows you to zero the balance.

•Marked calibrations demonstrate when the balance is level and zeroed.

•The balance contains a case with a lid to hold the masses. Storing your masses in this compartment will reduce the likelihood of misplacing them.

Use the balance in directed activities such as those listed below or simply place it in a Learning Center for students to explore. Either way, your Precision School Balance will expand and enrich the learning opportunities in your classroom.

Exploring the Precision School Balance

Collect a variety of classroom objects such as: pencils, erasers, paper clips, scissors, counters, or blocks. Encourage students to place objects on either side of the balance and observe the results. Ask questions that will increase your students’ explorations.

You might ask:

•Are there any objects that balance each other?

•Does size always tell which object has the greatest mass?

•Can a small object have greater mass than a large object?

After students have explored with objects on either side of the balance, encourage them to explore measurement with the unit masses provided with the balance. Students can place one object

•É melhor começar com massas unitárias pequenas para determinar a massa de um objecto?

•É melhor começar com massas unitárias grandes para determinar a massa de um objecto?

Ordenação de Massas

Peças aos alunos para organizarem os objectos que recolheram em função da massa. Os alunos devem seleccionar um objecto, determinar a sua massa e registar este valor numa tabela de dados. Depois de fazerem isto para todos os objectos, os alunos devem organizá-los por ordem de grandeza, começando com o objecto de menor massa até ao objecto de maior massa.

À Procura da Massa

Imagine um jogo "À Procura da Massa"! Segure num objecto e peça aos alunos para o identificar e em seguida determinar a sua massa. Desafie-os a procurarem na sala de aulas outro objecto com massa semelhante. Dê a cada aluno a oportunidade de seleccionar e rejeitar objectos até estarem de acordo relativamente ao objecto que pensam ter a massa mais semelhante à do objecto que seleccionou. Discuta a selecção feita pelos alunos e em seguida determine as massas dos objectos mais seleccionados para encontrar a melhor resposta.

LER 2420 specifications

Learning Resources LER 2420 is a versatile educational tool designed to foster early learning and engagement for young children. Specifically crafted for preschool and kindergarten-aged learners, this product encompasses a variety of features and technologies aimed at enhancing cognitive development through interactive play.

At the heart of the LER 2420 are its vibrant, tactile components that include colorful counting blocks, activity cards, and game pieces. These elements are made from durable, child-safe materials that ensure longevity and safety during use. The varied shapes and sizes of the blocks help facilitate hands-on learning experiences that promote creativity and problem-solving skills.

One of the standout characteristics of the LER 2420 is its emphasis on STEAM (Science, Technology, Engineering, Arts, and Mathematics) education. By integrating these key concepts into play, children are encouraged to explore and understand fundamental principles in an engaging manner. The accompanying activity cards guide educators and parents through a series of structured activities that can be tailored to different learning objectives.

The product also incorporates a range of interactive features that enhance learning through play. For example, the counting blocks facilitate lessons in basic math while promoting fine motor skills. Children can stack, sort, and manipulate the blocks, all of which serve to strengthen hand-eye coordination and spatial awareness.

In addition to its educational benefits, the LER 2420 is designed to encourage social interaction among children. Many activities can be completed in pairs or small groups, promoting teamwork, communication, and social skills. As children collaborate, they learn to share ideas, negotiate roles, and celebrate each other's achievements, making playtime a valuable opportunity for social development.

Moreover, the LER 2420 is suitable for various learning environments, including homes, classrooms, and daycare centers. Its compact design makes it easy to store and transport, allowing for flexible use in different settings.

In summary, Learning Resources LER 2420 is a remarkable educational resource that combines essential learning concepts with engaging, hands-on play. Through its innovative design, vibrant materials, and focus on STEAM education, it not only supports cognitive growth but also fosters essential social skills, making it a valuable addition to any early childhood learning toolkit.
